BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the steps of a processing method for a titanium-based anode provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0015] The implementation of the present invention will be described in detail below with specific embodiments.

[0016] Referring to Figure 1 as shown, a preferred embodiment is provided by the present invention.

[0017] In a first aspect, the present invention provides a processing method for a titanium-based anode, including:

[0018] S1: Using titanium metal material to prepare the substrate of the titanium-based anode to obtain the substrate part of the titanium-based anode; wherein, the substrate part of the titanium-based anode has a plate-shaped appearance and a pore structure;

[0019] S2: Perform structural analysis on the coating part of the titanium-based anode according to the substrate part to obtain a coating structure solution corresponding to the coating part; wherein, the coating structure solution includes a plurality of titanium-based coatings sequentially stacked on the substrate part of the titanium-based anode, and the titanium-based coating includes a guiding structure and a filling part. The guiding structure is used to be preset to perform filling guiding processing on the subsequent filling part, and the filling part is used to perform filling processing under the guidance of the guiding structure to obtain the titanium-based coating;

[0020] S3: Perform pre-treatment on the substrate part for coating processing;

[0021] S4: Prepare the guiding structure and filling part of each titanium-based coating on the substrate part in sequence according to the coating structure solution, so as to sequentially prepare each titanium-based coating on the substrate part, thereby completing the preparation of the coating part on the substrate part to obtain the titanium-based anode.

[0022] Specifically, in step S1 of the embodiment provided by the present invention, a titanium-based anode substrate is prepared using a titanium metal material to obtain the substrate part of the titanium-based anode; wherein, the substrate part of the titanium-based anode has a plate-like shape and a pore structure.

[0023] More specifically, the plate-like shape and pore structure of the substrate part are to increase the surface area of the substrate part, thereby enhancing the performance of the titanium-based anode obtained based on the substrate part. The pore structure has a large surface area, which is beneficial to the mechanical embedding of the coating material and the enhancement of adhesion. Through a reasonable coating process, this characteristic can be fully utilized to improve the stability of the coating. The pore structure provides a larger specific surface area, which is beneficial to improving the electrocatalytic activity of the anode. The coating material can act on more active sites, improving the electrolysis reaction efficiency.

[0024] More specifically, the titanium-based anode is composed of two parts, the substrate part as the basis, and the coating part provided on the substrate part. Among them, the function of the coating part is to protect the substrate part and enhance the performance of the titanium-based anode.

[0025] Specifically, in step S2 of the embodiment provided by the present invention, perform structural analysis on the coating part of the titanium-based anode according to the substrate part to obtain a coating structure solution corresponding to the coating part.

[0026] More specifically, the coating structure solution includes a plurality of titanium-based coatings sequentially stacked on the substrate part of the titanium-based anode. The titanium-based coating includes a guiding structure and a filling part. The guiding structure is used to be preset to perform filling guiding processing on the subsequent filling part, and the filling part is used to perform filling processing under the guidance of the guiding structure to obtain the titanium-based coating.

[0027] More specifically, in the embodiments provided by the present invention, the surface coating portion of the titanium-based anode is prepared into a multi-layer coating form using different types of materials. This method can effectively improve the performance of the anode and extend its service life.

[0028] More specifically, these titanium-based coatings can be divided into a bottom layer coating, an intermediate layer coating, and a surface layer coating according to their relative positional relationship with the substrate portion.

[0029] More specifically, materials such as titanium oxide, tantalum oxide, or tin oxide are usually used for the bottom layer coating. These materials have good adhesion and corrosion resistance. The bottom layer coating mainly serves to increase the adhesion between the coating and the substrate, provide preliminary corrosion protection, and can also serve as a smooth substrate for subsequent coatings to ensure the uniformity and stability of the upper layer coating.

[0030] More specifically, ruthenium oxide, iridium oxide, or their mixed oxides are often used for the intermediate layer coating. The main function of the intermediate layer coating is to provide high electrocatalytic activity, reduce the overpotential during the electrolysis process, improve the electrolysis efficiency, and can further enhance the corrosion resistance of the anode.

[0031] More specifically, iridium oxide, platinum, or mixed metal oxides can be used for the surface layer coating. The selected materials usually have the highest electrocatalytic activity and the best corrosion resistance. The surface layer coating is directly exposed to the electrolysis medium and needs to have the highest electrocatalytic activity and corrosion resistance. Its main role is to improve the electrolysis efficiency and extend the service life of the anode.

[0032] It can be understood that the sequential setting of the multi-layer titanium-based coatings can significantly improve the electrocatalytic activity of the anode, reduce the overpotential of the electrolysis reaction, improve the reaction efficiency, and enhance the stability and service life of the anode in a harsh environment by selecting materials with excellent corrosion resistance, especially in the bottom layer and the intermediate layer. The multi-layer coating design can alleviate the problems of coating peeling and substrate corrosion, ensuring the stability and reliability of the anode during long-term use.

[0033] More specifically, in the design of each titanium-based coating, a guiding portion and a filling portion are included. The guiding portion is set in advance to guide the subsequent filling portion, and the filling portion performs a filling operation under the guiding action of the guiding portion to complete the preparation of the coating.

[0034] It can be understood that the purpose of setting the guiding portion first to guide the filling portion is to make the coating setting more uniform and perfect, so as to avoid the difficult problem of coating preparation caused by the pore structure.

[0035] Specifically, in step S3 of the embodiments provided by the present invention, pre-treatment of coating processing is performed on the substrate portion.

[0036] More specifically, the base part is prepared from a titanium metal material. High-purity titanium or a titanium alloy is selected as the base material. Titanium usually uses commercially pure titanium because they have good corrosion resistance and electrical conductivity. The surface pretreatment of the titanium base material is a key step to ensure the adhesion and uniformity of the coating.

[0037] Specifically, in step S4 of the embodiment provided by the present invention, according to the coating structure scheme, the guiding structure and the filling part of each titanium-based coating are sequentially prepared on the base part to sequentially prepare each titanium-based coating on the base part, so as to complete the preparation of the coating part on the base part to obtain a titanium-based anode.

[0038] It can be understood that the coating structure scheme is the design plan for the coating part. For different forms of the base part, the specific design plans for the most suitable coating parts are different. Therefore, it is necessary to perform corresponding analysis and processing on the base part to obtain the coating structure scheme for designing its coating part.

[0039] More specifically, the content of the design plan for the coating part mainly includes: the thickness of each titanium-based coating, the form of the guiding structure of the titanium-based coating corresponding to this thickness, and the preparation method of the filling part of the titanium-based coating corresponding to this thickness. It can be seen that the main content of the analysis is the thickness of each titanium-based coating, and the subsequent design content is extended from this thickness.

[0040] More specifically, for different forms of the base part, the overall thickness of the coating part provided thereon is inconsistent because it is necessary to make an adaptive adjustment according to the plate shape and pore structure of the base part to avoid the phenomenon of coating clogging the pore structure or uneven coating. Therefore, corresponding coating parts need to be analyzed for different base parts.

[0041] More specifically, according to the coating structure scheme, the guiding structure and the filling part of each titanium-based coating are sequentially prepared on the base part, that is, the guiding structure is prepared first and then the filling part is prepared, and so on in a cycle to sequentially prepare each titanium-based coating on the base part, so as to complete the preparation of the coating part on the base part to obtain a titanium-based anode.

[0042] The present invention provides a processing method for a titanium-based anode, which has the following beneficial effects:

[0043] The present invention uses titanium metal to prepare a plate-shaped substrate, forms a titanium-based anode substrate part with a pore structure, designs a coating structure scheme according to the substrate part, determines the order and composition of the stacked coatings, performs surface pretreatment on the substrate part to enhance the coating adhesion, and according to the coating structure scheme, sequentially prepares the guiding structure and filling part of each layer of coating on the substrate, and completes the preparation of the titanium-based coating layer by layer to obtain a complete titanium-based anode. The multi-layer coating structure enhances the corrosion resistance of the anode, is applicable to various corrosive environments, optimizes the coating materials and structure, improves the current efficiency and conductivity. The multi-layer structure and pore design enhance the mechanical strength and stability of the anode. The guiding structure ensures uniform filling and improves the electro-chemical reaction efficiency, solving the problem that the coating is prone to unevenness in the prior art when preparing a titanium-based anode with a pore structure and a multi-layer coating.

[0044] Preferably, the steps of using a titanium metal material to prepare the substrate of the titanium-based anode to obtain the substrate part of the titanium-based anode include:

[0045] S11: Obtain the design scheme of the substrate part of the titanium-based anode, and perform scheme analysis processing on the design scheme of the substrate part of the titanium-based anode to obtain the plate-shaped outer shape information and pore structure information of the substrate part of the titanium-based anode;

[0046] S12: Process the titanium metal material according to the plate-shaped outer shape information to obtain a titanium metal material with a plate-shaped outer shape;

[0047] S13: Process the pore structure on the titanium metal material with a plate-shaped outer shape according to the pore structure information to obtain the substrate part of the titanium-based anode with a plate-shaped outer shape and a pore structure.

[0048] Specifically, obtain the detailed design scheme of the substrate part of the titanium-based anode, including the plate-shaped outer shape and pore structure information, use computer-aided design (CAD) software to analyze the design scheme, extract the plate-shaped outer shape information and pore structure information, and generate corresponding processing drawings and data files.

[0049] More specifically, select a high-purity titanium metal material to ensure that the material quality and purity meet the requirements of anode applications. According to the plate-shaped outer shape information, use techniques such as mechanical cutting, laser cutting or water cutting to cut the titanium metal material into the required plate-shaped outer shape, and perform surface treatment on the cut titanium plate, such as grinding and polishing, to obtain a flat and smooth surface for the subsequent processing of the pore structure.

[0050] More specifically, according to the pore structure information, mark the pore positions and sizes on the titanium plate to ensure the accuracy of pore processing. Use equipment such as numerically controlled drilling machines, laser drilling machines, or electrical discharge machining machines to perform pore processing on the titanium plate. During the processing, it is necessary to strictly control the pore diameter and pore spacing to ensure the uniformity and accuracy of the pore structure.

[0051] More specifically, after processing, perform ultrasonic cleaning and chemical deburring on the titanium plate to remove the residues and burrs inside the pores, ensuring the cleanliness and smoothness of the pore structure. Use measuring tools and equipment to detect the external dimensions of the processed titanium plate to ensure it meets the design requirements. Use equipment such as three-dimensional scanners to detect the pore structure, verify the accuracy of the pore diameter, pore spacing, and pore distribution, and conduct mechanical property and electrochemical property tests to verify performance indicators such as the strength, corrosion resistance, and conductivity of the titanium-based anode substrate part.

[0052] It can be understood that through precise cutting and forming processes, ensure that the titanium-based anode substrate part has an accurate plate-like shape and a uniform pore structure. The pore structure increases the specific surface area of the titanium-based anode, provides more active sites, enhances the adhesion of the coating, and the efficiency of the electrochemical reaction.

[0053] Preferably, the steps of performing structural analysis processing on the coating part of the titanium-based anode according to the substrate part to obtain a coating structure scheme corresponding to the coating part include:

[0054] S21: Construct a corresponding digital twin model according to the substrate part of the titanium-based anode to obtain a substrate digital model for digital simulation feedback of the substrate part; wherein, the substrate digital model includes a flat plate model and a pore model. The flat plate model is used for digital simulation feedback of the plate-like shape of the substrate part, and the pore model is set on the flat plate model. The pore model is used for digital simulation feedback of the pore structure of the substrate part;

[0055] S22: Construct a coating digital model based on the substrate digital model to obtain a coating digital model set on the substrate digital model; wherein, the coating digital model is used for digital simulation feedback of the coating part;

[0056] S23: Use the coating digital model as the mapping main body, the coating effect of the coating digital model as the mapping object, and the simulation rule of the coating effect of the coating digital model as the mapping relationship. Perform association processing on the mapping main body and the mapping object according to the mapping relationship;

[0057] S24: Perform a traversal adjustment substitution process on the coating setting parameters based on the coating digital model as the mapping main body to obtain the coating effect characteristics of each coating setting parameter corresponding to the traversal adjustment substitution process of the mapping object, and use the coating effect characteristics together as an effect evaluation map; wherein, the coating effect characteristics are used to describe the coating effect of the coating digital model.

[0058] S25: Analyze and process the effect evaluation map to determine the optimal coating effect characteristics in the effect evaluation map, and generate a coating structure plan for the coating part according to the coating setting parameters corresponding to the optimal coating effect characteristics.

[0059] Specifically, collect the design data of the plate shape and pore structure of the titanium-based anode substrate part, and use computer-aided design (CAD) and finite element analysis (FEA) software, such as SolidWorks, ANSYS, etc., to construct a substrate digital model. According to the plate shape data, establish a flat plate model of the substrate part in the CAD software, perform digital simulation feedback on the size and geometric shape, and add a pore model to the flat plate model according to the pore structure data to ensure that the size, distribution, and shape of the pores are consistent with the actual situation.

[0060] More specifically, determine the material used for the coating and collect its physical and chemical property data, stack the coating material on the substrate digital model to construct a coating digital model, ensure that the coating thickness, number of layers, and coverage are consistent with the actual design, and optimize the uniformity and performance of the coating through numerical simulation feedback on the adhesion and coverage of the coating on the substrate.

[0061] It should be noted that in the subsequent steps, the coating digital model will be continuously adjusted to change its specific form, and the performance of each form of the coating digital model will be predicted to obtain the best specific form of the coating digital model. Therefore, the coating digital model established in this step is a basic model established according to preset data, and this basic model can be transformed by changing the setting parameters to transform the specific form of the coating digital model.

[0062] More specifically, define the simulation rules of the coating effect, such as the influence of the coating thickness on the adhesion and electrochemical performance, and the influence of the coating on pore blockage. Use the coating digital model as the mapping main body, establish a mapping relationship according to the simulation rules, and generate a coating effect characteristic description model.

[0063] More specifically, define the coating setting parameters, such as coating thickness, coating material ratio, coating process conditions, etc., use optimization algorithms, such as genetic algorithms, particle swarm optimization, etc., to traverse various coating setting parameters, calculate and record the corresponding coating effect characteristics, and jointly plot the coating effect characteristics of each coating setting parameter into an effect evaluation map.

[0064] More specifically, analyze the effect evaluation map, determine the optimal coating effect characteristics, evaluate the influence of different setting parameters on the coating performance, select the best coating setting parameters according to the optimal coating effect characteristics, and generate the final coating structure plan for the coating part.

[0065] It can be understood that through the construction of the digital twin model, accurate digital simulations of the titanium-based anode substrate part and the coating part are realized, providing a reliable virtual test platform. The digital model reflects the real substrate shape and pore structure, ensuring the accuracy and effectiveness of the coating simulation. Using the coating digital model and the mapping relationship, the adhesion and coverage effects of the coating on the substrate are simulated and optimized, improving the uniformity and performance of the coating. The traversal adjustment and effect evaluation of the coating setting parameters ensure that the selected coating scheme performs optimally in practical applications. The determination of the optimal coating setting parameters ensures that the coating has good adhesion, electrochemical performance, and corrosion resistance, extending the service life of the titanium-based anode. Through digital simulation and optimization, the functionality and stability of the coating are improved, enhancing the overall performance of the titanium-based anode. The digital twin model and virtual tests reduce the number and cost of actual experiments, accelerating the R & D process. Through simulation feedback and optimization, the trial-and-error links are reduced, improving the efficiency of coating design and manufacturing.

[0066] Preferably, taking the coating digital model as the mapping subject, the coating effect of the coating digital model as the mapping object, and the simulation rules of the coating effect of the coating digital model as the mapping relationship, the steps of performing association processing on the mapping subject and the mapping object according to the mapping relationship include:

[0067] S231: Construct a number of coating effect analysis items based on the coating digital model; wherein, the coating effect analysis items are used to reflect the coating effect of the coating digital model in a specified aspect;

[0068] S232: Analyze and process the association relationships between the coating digital model and each of the coating effect analysis items to obtain the association relationships between the coating digital model and each of the coating effect analysis items, and jointly use the association relationships between the coating digital model and each of the coating effect analysis items as the simulation rules of the coating effect of the coating digital model;

[0069] S233: Take the coating digital model as the mapping subject, jointly take each of the coating effect analysis items as the mapping object, and take the simulation rules of the coating effect of the coating digital model as the mapping relationship between the mapping subject and the mapping object; wherein, each of the coating effect analysis items is used to jointly describe the coating effect of the coating digital model.

[0070] Specifically, according to the expected performance of the coating, several coating effect analysis items are determined, such as the influence of the coating part on the pore structure of the substrate part, the adhesion effect, electrochemical performance, and corrosion resistance corresponding to the structural form of the coating part. The effect data of each item is associated with the thickness form of the coating.

[0071] More specifically, the coating digital model is simulated and analyzed under different coating setting parameters, including the simulation test results of each analysis item. Statistical analysis tools or machine learning algorithms, such as multiple regression analysis, principal component analysis (PCA), etc., are used to analyze the correlation between the coating digital model and each coating effect analysis item. According to the analysis results of the correlation, a mathematical model or prediction model between the coating digital model and each coating effect analysis item is established, and these correlations are used as the simulation rules of the coating effect.

[0072] More specifically, the coating digital model is used as the mapping main body and the basic model for analysis and optimization, and each coating effect analysis item is used as the mapping object together. These objects are used to evaluate the performance of the coating digital model under different setting parameters. Applying the established coating effect simulation rules, the coating digital model and each analysis item are mapped to predict and evaluate the coating effect characteristics under different coating setting parameters.

[0073] More specifically, based on the mapping relationship, the coating digital model is simulated and calculated to obtain the coating effect characteristics under different setting parameters. Optimization algorithms (such as genetic algorithms, particle swarm optimization) are used to traverse and adjust the coating setting parameters to optimize the coating effect characteristics and select the optimal coating setting parameters.

[0074] It can be understood that through the construction of coating effect analysis items and the analysis of correlation relationships, the performance of the coating under different setting parameters can be accurately predicted, the number of actual tests can be reduced, and the simulation rules of the coating effect provide a reliable theoretical basis to ensure the accuracy and repeatability of the simulation results. Through simulation and optimization, the optimal coating setting parameters can be selected to improve the adhesion, electrochemical performance, corrosion resistance, and wear resistance of the coating. The optimized coating design can show better performance and longer service life in practical applications.

[0075] Preferably, the step of traversing and adjusting the coating setting parameters based on the coating digital model as the mapping main body and substituting them to obtain the coating effect characteristics of each coating setting parameter corresponding to the traversing and adjusting substitution as the mapping object, and using these coating effect characteristics together as the effect evaluation map includes:

[0076] S241: Perform analysis and processing based on the base digital model to obtain several basic setting parameters of the coating digital model; wherein, one of the basic setting parameters is used to describe a specific setting method of the coating digital model;

[0077] S242: Substitute several of the basic setting parameters into the coating digital model as the mapping subject respectively, and perform mapping processing on the coating digital model with the basic setting parameters substituted according to the mapping relationship to obtain the analysis results of each coating effect analysis item as the mapping object, and use the analysis results of each coating effect analysis item as the mapping object as coating effect characteristics;

[0078] S243: Perform effect evaluation processing on each of the coating effect characteristics to obtain the characteristic evaluation index of each of the coating effect characteristics;

[0079] S244: Sort each of the basic setting parameters according to the exponential magnitude relationship of the characteristic evaluation indices of each of the coating effect characteristics to obtain a setting parameter characteristic sequence; wherein, the setting parameter characteristic sequence includes several of the basic setting parameters arranged in sequence;

[0080] S245: Perform analysis processing on the parameter trends among the basic setting parameters of the setting parameter characteristic sequence to obtain the parameter trends among the basic setting parameters of the setting parameter characteristic sequence;

[0081] S246: Perform optimization processing on the basis of each of the basic setting parameters according to the parameter trends among the basic setting parameters of the setting parameter characteristic sequence to obtain several optimized setting parameters;

[0082] S247: Substitute several of the optimized setting parameters into the coating digital model as the mapping subject respectively, and perform mapping processing on the coating digital model with the optimized setting parameters substituted according to the mapping relationship to obtain the analysis results of each coating effect analysis item as the mapping object, and use the analysis results of each coating effect analysis item as the mapping object as coating effect characteristics;

[0083] S248: Perform effect evaluation processing on the coating effect characteristics corresponding to each of the optimized setting parameters to obtain the characteristic evaluation index of each of the coating effect characteristics;

[0084] S249: Arrange the coating effect characteristics corresponding to each of the basic setting parameters and each of the optimized setting parameters according to the characteristic evaluation index to obtain an effect evaluation map.

[0085] Specifically, based on the base digital model of the titanium-based anode, its physical properties and design parameters are analyzed to determine several basic coating setting parameters, such as coating thickness, coating material composition, coating process conditions, etc. Each basic setting parameter describes a specific coating setting method, for example, the deposition method of a coating with a specific thickness at a specific temperature.

[0086] More specifically, several basic setting parameters are respectively substituted into the coating digital model. According to the simulation rules of the coating effect, mapping processing is performed on the coating digital model substituted with the basic setting parameters to obtain the analysis results of each coating effect analysis item, and the analysis results of the coating effect analysis item are used as the coating effect characteristics.

[0087] More specifically, effect evaluation processing is performed on each coating effect characteristic, the characteristic evaluation index is calculated, and according to the magnitude of the characteristic evaluation index, each basic setting parameter is sorted to generate a setting parameter characteristic sequence. Based on the setting parameter characteristic sequence, the trend relationship between each basic setting parameter is analyzed to find out the influence law of parameter change on the coating effect. According to the parameter trend, the basic setting parameters are optimized to generate several optimized setting parameters. The optimized setting parameters are respectively substituted into the coating digital model. According to the simulation rules of the coating effect, mapping processing is performed on the coating digital model substituted with the optimized setting parameters to obtain the analysis results of each coating effect analysis item, and the analysis results of the coating effect analysis item corresponding to the optimized setting parameters are used as the coating effect characteristics. Effect evaluation processing is performed on the coating effect characteristics of the optimized setting parameters, the characteristic evaluation index is calculated, and according to the characteristic evaluation index, the coating effect characteristics of the basic setting parameters and the optimized setting parameters are arranged to generate an effect evaluation map.

[0088] It can be understood that through the precise analysis and adjustment of the basic setting parameters and the optimized setting parameters, the coating performance can be effectively optimized, and the adhesion, electrochemical performance, corrosion resistance, and wear resistance of the coating can be improved. The parameter trend analysis provides a theoretical basis for optimizing the setting parameters, ensuring the scientificity and rationality of the optimization process. By calculating the characteristic evaluation index, the coating effects under different parameter settings are quantitatively evaluated, providing a reliable basis for selecting the optimal coating setting parameters. The effect evaluation map intuitively shows the advantages and disadvantages of the coating effects under different parameter settings, facilitating comparison and decision-making. By substituting and evaluating the optimized setting parameters, the overall performance of the coating can be significantly improved, the service life of the titanium-based anode can be extended, and its reliability and stability in practical applications can be enhanced. The optimized coating design shows better performance in various application scenarios and meets different requirements.

[0089] Preferably, the steps for performing coating processing pretreatment on the base part include:

[0090] S31: Mechanically polish the substrate part to remove the oxides and oil stains on the surface of the substrate part;

[0091] S32: Pickle the substrate part to remove the impurities on the surface of the substrate part and produce a uniform oxide film;

[0092] S33: Place the substrate part in deionized water for cleaning to passivate the substrate part and make the oxide film on the surface of the substrate part in a stable state for subsequent coating setting.

[0093] Specifically, use an appropriate solvent to clean the oil stains and visible impurities on the surface of the substrate part, and use sandpaper, grinding wheel or polishing machine to mechanically polish the substrate surface to remove the oxides and fine oil stains on the surface. During the polishing process, uniform force and speed should be maintained to ensure the surface is flat and smooth. After polishing, use compressed air to blow off the residual dust on the surface, and wipe and clean the substrate surface with anhydrous ethanol or other appropriate solvents.

[0094] More specifically, prepare an appropriate concentration of pickling solution (such as dilute sulfuric acid or dilute hydrochloric acid). The concentration and temperature of the pickling solution should be determined according to the properties of the substrate material. Immerse the mechanically polished substrate part in the pickling solution and keep it for a certain time to remove the impurities and residual oxides on the surface. Stirring or slight vibration should be carried out during the pickling process to ensure uniform pickling effect. After pickling, take out the substrate part from the pickling solution and thoroughly clean it with a large amount of deionized water to remove the residual acid solution.

[0095] More specifically, place the pickled substrate part in deionized water for preliminary cleaning to remove the residual acid solution and impurities on the surface. Continue to place the substrate part in fresh deionized water and soak it for a certain time to form a uniform and stable oxide film on the surface. The soaking time and water temperature should be adjusted according to the properties and requirements of the substrate material. After the passivation treatment is completed, take out the substrate part from the deionized water and dry it with a lint-free cloth or blow it dry with compressed air to ensure that there is no water stain and impurity on the surface.

[0096] It can be understood that mechanical polishing and pickling treatment effectively remove oxides, oil stains and impurities on the substrate surface, ensuring a closer bond between the coating and the substrate, improving the adhesion and durability of the coating. Deionized water cleaning and passivation treatment further improve the cleanliness of the substrate surface, preventing residual impurities from affecting the coating quality. Pickling treatment forms a uniform oxide film on the substrate surface, providing a good interfacial state and promoting the uniform coverage and adhesion of the subsequent coating. Passivation treatment keeps the oxide film in a stable state, preventing the destruction or non-uniformity of the oxide film during the coating processing, ensuring the consistency of the coating quality. Through pretreatment, the substrate surface has good physical and chemical states, ensuring the adhesion and durability of the coating after coating and improving the overall performance of the coating. The uniform oxide film provides better protection for the coating, enhancing the corrosion resistance and service life of the coating.

[0097] Preferably, according to the coating structure scheme, the preparation of the guiding structure and the filling part of each titanium-based coating is sequentially carried out on the substrate part. The steps of sequentially preparing each titanium-based coating on the substrate part include:

[0098] S41: Analyze the coating structure scheme to obtain each titanium-based coating on the substrate part and the setting order of each titanium-based coating;

[0099] S42: According to the titanium-based coating with the earliest setting order, prepare the corresponding guiding structure on the substrate part to generate the corresponding guiding structure on the substrate part;

[0100] S43: Coat the substrate part provided with the guiding structure with the precursor solution of the coating material, so that the precursor solution of the coating material is coated on the surface of the substrate part under the guidance of the guiding structure, and perform heat treatment on the substrate part that has completed the coating treatment to prepare the corresponding titanium-based coating;

[0101] S44: Repeat the above steps in a loop until the preparation of all titanium-based coatings is completed.

[0102] Specifically, analyze the coating structure scheme, determine the specific composition, thickness, material type and coating order of each titanium-based coating on the substrate part. According to the coating structure scheme, determine the setting order of each titanium-based coating and proceed layer by layer starting from the earliest set coating.

[0103] More specifically, according to the requirements of the titanium-based coating in the first-setting sequence, a suitable guiding structure material is selected to prepare the guiding structure on the substrate part, so that the guiding structure uniformly covers the substrate surface, provides a good adhesion interface, and the substrate with the guiding structure is subjected to appropriate heat treatment (such as drying, annealing) to improve the stability and adhesion of the guiding structure.

[0104] More specifically, according to the requirements of the coating material, a suitable precursor solution of the coating material is formulated, such as titanate solution, titanium oxide solution, etc. The precursor solution of the coating material is uniformly coated on the surface of the substrate with the guiding structure by spraying, spin-coating or dip-coating methods, ensuring that the precursor solution is uniformly distributed under the guidance of the guiding structure. The substrate after the coating treatment is subjected to heat treatment, such as drying, annealing or sintering, so that the precursor solution is converted into a stable titanium-based coating.

[0105] More specifically, repeat the guiding structure and coating treatment: according to the sequence in the coating structure scheme, sequentially carry out the preparation of the guiding structure and the coating treatment of the precursor solution for each titanium-based coating, and carry out the corresponding heat treatment until the preparation of all titanium-based coatings is completed. After all the coatings are prepared, overall heat treatment is carried out to improve the bonding strength and overall stability of the multi-layer titanium-based coating.

[0106] It can be understood that the guiding structure of each layer of the coating ensures the uniform distribution and good adhesion of the coating material on the substrate surface, improves the uniformity and performance of the coating. The design and optimization of the layered structure make the coating perform excellently in various properties, such as corrosion resistance, mechanical strength and conductivity. Through multiple heat treatment processes, each layer of coating material is fully converted and stabilized, forming a dense and strongly adhesive coating structure, improving the durability and performance stability of the coating. The optimized precursor solution of the coating material and the coating process ensure the high quality and consistency of the coating, meeting different application requirements.

[0107] Preferably, the method for preparing the corresponding guiding structure on the substrate part is anodic oxidation technology, micro-machining technology or chemical vapor deposition technology.

[0108] Specifically, anodic oxidation pretreatment: formulate a suitable electrolyte solution (such as sulfuric acid, phosphoric acid or oxalic acid solution), and adjust the concentration and temperature of the solution. Immerse the substrate as the anode into the electrolyte solution and apply a constant current or voltage. According to the characteristics of the required oxide film, control the oxidation time and conditions. After oxidation, thoroughly wash the substrate with deionized water to remove the residual electrolyte solution, and then dry it.

[0109] Specifically, for micromachining technology: Similar to the anodic oxidation pretreatment, ensure the cleanliness of the substrate surface. As needed, apply a protective coating to the non-machining areas to prevent unnecessary material removal. Select a suitable micromachining device, such as a micro drill, a laser etching machine, or an ion beam machining device. According to the design requirements, perform precise microstructural machining to fabricate the required guiding structure. Control the machining parameters (such as feed rate, laser power) to achieve the best effect. Remove the protective coating and clean the substrate surface with deionized water.

[0110] Specifically, for chemical vapor deposition technology: Clean the substrate surface to ensure no contaminants and oxides. Preheat the substrate before deposition to improve the coating adhesion. Select suitable reaction gases and carrier gases (such as titanium tetrachloride and hydrogen), and adjust the gas flow rate and ratio. Under high-temperature conditions (usually 500°C to 1000°C), place the substrate in the reaction chamber, and the reaction gases chemically react on the substrate surface to form the guiding structure. Control the deposition time to achieve the required thickness. After deposition, slowly cool the substrate and clean it with deionized water to remove possible chemical residues.

[0111] It can be understood that anodic oxidation can form a uniform and dense oxide film on the substrate surface, increasing the surface hardness and corrosion resistance. By adjusting the oxidation parameters, the pore size and thickness of the oxide film can be controlled, which helps to improve the coating adhesion. The micromachining technology can fabricate high-precision microstructures to guide the uniform deposition of the coating material, and the processing process can be flexibly adjusted according to different design requirements to obtain the required structure. Chemical vapor deposition can form a high-purity guiding structure on the substrate surface, providing excellent corrosion resistance and mechanical properties. Through chemical reaction deposition, the formed coating has good chemical bonding with the substrate, improving the overall coating performance.
