BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic diagram of the steps of a method for processing a titanium-based anode provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0009] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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 intended to limit the present invention.

[0010] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0011] Reference Figure 1 As shown, a preferred embodiment of the present invention is provided.

[0012] In a first aspect, the present invention provides a method for processing a titanium-based anode, comprising: S1: using titanium metal material to prepare a base of a titanium-based anode to obtain a base portion of the titanium-based anode; wherein the base portion of the titanium-based anode is plate-shaped and has a porous structure; S2: Performing structural analysis 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; wherein the coating structure scheme 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 guide structure and a filling part, wherein the guide structure is used to pre-set to perform a filling guide treatment on the subsequent filling part, and the filling part is used to perform a filling treatment under the guidance of the guide structure to obtain the titanium-based coating; S3: performing coating pretreatment on the substrate portion; S4: According to the coating structure scheme, the guide structure and the filling part of each titanium-based coating are prepared on the base part in sequence, so as to prepare each titanium-based coating on the base part in sequence, thereby completing the preparation of the coating part on the base part to obtain the titanium-based anode.

[0013] Specifically, in step S1 of the embodiment provided by the present invention, a titanium metal material is used to prepare the substrate of the titanium-based anode to obtain the substrate portion of the titanium-based anode; wherein the substrate portion of the titanium-based anode is plate-shaped and has a porous structure.

[0014] More specifically, the plate-like shape and pore structure of the base part are intended to increase the surface area of ​​the base part, thereby enhancing the performance of the titanium-based anode obtained based on the base part. The large surface area of ​​the pore structure is beneficial to the mechanical intercalation and adhesion enhancement of the coating material. 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 play a role at more active sites and improve the efficiency of the electrolysis reaction.

[0015] More specifically, the titanium-based anode is composed of two parts: a base part as a foundation, and a coating part arranged on the base part, wherein the coating part functions to protect the base part and enhance the performance of the titanium-based anode.

[0016] Specifically, in step S2 of the embodiment provided by the present invention, a structural analysis process is performed on the coating portion of the titanium-based anode according to the substrate portion to obtain a coating structure scheme corresponding to the coating portion.

[0017] More specifically, the coating structure scheme includes a plurality of titanium-based coatings sequentially stacked on a titanium-based anode on a substrate portion, the titanium-based coating including a guide structure and a filling portion, the guide structure being used for pre-setting to guide the subsequent filling portion, and the filling portion being used for performing a filling process under the guidance of the guide structure to obtain the titanium-based coating.

[0018] 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 using different types of materials. This method can effectively improve the performance of the anode and extend its service life.

[0019] More specifically, these titanium-based coatings can be divided into a base coating, an intermediate coating, and a surface coating according to their relative positional relationship with the substrate portion.

[0020] More specifically, the base coating usually uses materials such as titanium oxide, tantalum oxide or tin oxide, which have good adhesion and corrosion resistance. The base coating mainly increases the adhesion between the coating and the substrate and provides preliminary corrosion protection. It can also serve as a smooth base for subsequent coatings to ensure the uniformity and stability of the upper coating.

[0021] More specifically, the intermediate coating often uses ruthenium oxide, iridium oxide or a mixed oxide thereof. The main function of the intermediate coating is to provide high electrocatalytic activity, reduce the overpotential during the electrolysis process, improve the electrolysis efficiency, and further enhance the corrosion resistance of the anode.

[0022] More specifically, the surface coating can use iridium oxide, platinum or mixed metal oxides. The selected materials are usually those with the highest electrocatalytic activity and the best corrosion resistance. The surface coating is directly exposed to the electrolytic medium and needs to have the highest electrocatalytic activity and corrosion resistance. Its main function is to improve the electrolysis efficiency and extend the service life of the anode.

[0023] It can be understood that the sequential setting of multiple layers of titanium-based coatings can significantly improve the electrocatalytic activity of the anode, reduce the overpotential of the electrolysis reaction, and improve the reaction efficiency. By selecting materials with excellent corrosion resistance, especially in the bottom and middle layers, the stability and service life of the anode in harsh environments can be enhanced. The multi-layer coating design can alleviate the problems of coating peeling and substrate corrosion, ensuring the stability and reliability of the anode in long-term use.

[0024] More specifically, the design of each titanium-based coating includes a guiding part and a filling part. The guiding part is pre-set to guide the subsequent filling part, and the filling part performs a filling operation under the guidance of the guiding part to complete the preparation of the coating.

[0025] It can be understood that the purpose of first setting the guide part to guide the filling part is to make the coating setting more uniform and perfect, so as to avoid the difficulty of coating preparation caused by the pore structure.

[0026] Specifically, in step S3 of the embodiment provided by the present invention, the substrate portion is subjected to coating pretreatment.

[0027] More specifically, the substrate is made of titanium metal material. High-purity titanium or titanium alloy is selected as the substrate. Commercially pure titanium is usually used because of its good corrosion resistance and conductivity. Surface pretreatment of the titanium substrate is a key step to ensure coating adhesion and uniformity.

[0028] Specifically, in step S4 of the embodiment provided by the present invention, the guiding structure and the filling part of each titanium-based coating are prepared in sequence on the substrate part according to the coating structure scheme, so as to prepare each titanium-based coating on the substrate part in sequence, thereby completing the preparation of the coating part on the substrate part to obtain a titanium-based anode.

[0029] It can be understood that the coating structure scheme is a design plan for the coating part. For different forms of substrate parts, the specific design plan of the most suitable coating part is different. Therefore, it is necessary to perform corresponding analysis and processing on the substrate part to obtain the coating structure scheme for designing its coating part.

[0030] More specifically, the design planning content of 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 analysis content is the thickness of each titanium-based coating, and the subsequent design content is extended from this thickness.

[0031] More specifically, corresponding to different forms of substrate parts, the overall thickness of the coating part arranged thereon is inconsistent. This is because it is necessary to make adaptive adjustments according to the plate-like shape and pore structure of the substrate part to avoid clogging of the pore structure or uneven coating caused by the coating. Therefore, it is necessary to analyze the corresponding coating part corresponding to different substrate parts.

[0032] More specifically, according to the coating structure scheme, the guide structure and the filling part of each titanium-based coating are prepared on the substrate part in sequence, that is, the guide structure is prepared first and then the filling part is prepared, and this cycle is repeated to prepare each titanium-based coating on the substrate part in sequence, thereby completing the preparation of the coating part on the substrate part to obtain a titanium-based anode.

[0033] The present invention provides a method for processing a titanium-based anode, which has the following beneficial effects: The present invention uses titanium metal to prepare a plate-like substrate to form 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 superimposed coatings, performs surface pretreatment on the substrate part to enhance the adhesion of the coating, and sequentially prepares a guide structure and a filling part of each layer of coating on the substrate according to the coating structure scheme, completes the preparation of the titanium-based coating layer by layer, and obtains a complete titanium-based anode. The multi-layer coating structure enhances the corrosion resistance of the anode, is suitable for a variety of corrosive environments, optimizes the coating material 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 guide structure ensures uniform filling, and improves the electrochemical reaction efficiency, thereby solving the problem of uneven coating in the prior art when preparing a titanium-based anode with a pore structure and a multi-layer coating.

[0034] Preferably, the step of preparing the substrate of the titanium-based anode by using titanium metal material to obtain the substrate portion of the titanium-based anode comprises: S11: obtaining a design scheme of the base portion of the titanium-based anode, and performing scheme analysis processing on the design scheme of the base portion of the titanium-based anode to obtain plate shape information and pore structure information of the base portion of the titanium-based anode; S12: performing plate-shaped shape processing on the titanium metal material according to the plate-shaped shape information to obtain a titanium metal material with a plate-shaped shape; S13: performing pore structure processing on the titanium metal material having a plate-like shape according to the pore structure information to obtain a base portion of the titanium-based anode having a plate-like shape and a pore structure.

[0035] Specifically, a detailed design plan of the titanium-based anode substrate, including plate shape and pore structure information, is obtained, and the design plan is analyzed using computer-aided design (CAD) software to extract the plate shape information and pore structure information, and generate corresponding processing drawings and data files.

[0036] More specifically, high-purity titanium metal materials are selected to ensure that the material quality and purity meet the requirements of anode applications. According to the plate shape information, mechanical cutting, laser cutting or water cutting techniques are used to cut the titanium metal materials into the required plate shape. The cut titanium plates are subjected to surface treatment such as grinding and polishing to obtain a flat and smooth surface, in preparation for the subsequent processing of the pore structure.

[0037] More specifically, according to the pore structure information, the pore position and size are marked on the titanium plate to ensure the accuracy of the pore processing. The pore processing is performed on the titanium plate using equipment such as CNC drilling machines, laser punching machines or electric spark processing machines. During the processing, the pore diameter and hole spacing need to be strictly controlled to ensure the uniformity and accuracy of the pore structure.

[0038] More specifically, after processing, the titanium plate is ultrasonically cleaned and chemically deburred to remove residues and burrs in the pores to ensure the cleanliness and smoothness of the pore structure. Measuring tools and equipment are used to detect the external dimensions of the processed titanium plate to ensure that it meets the design requirements. A 3D scanner and other equipment is used to detect the pore structure to verify the accuracy of the pore size, pore spacing and pore distribution. Mechanical and electrochemical performance tests are carried out to verify the performance indicators of the titanium-based anode base, such as strength, corrosion resistance and electrical conductivity.

[0039] It can be understood that through precise cutting and forming processes, it is ensured that the titanium-based anode base 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, and enhances the adhesion of the coating and the efficiency of the electrochemical reaction.

[0040] Preferably, the step of performing structural analysis on the coating portion of the titanium-based anode according to the substrate portion to obtain a coating structure scheme corresponding to the coating portion comprises: S21: constructing a corresponding digital twin model according to the substrate part of the titanium-based anode to obtain a substrate digital model for performing digital simulation feedback on the substrate part; wherein the substrate digital model includes a flat plate model and a pore model, the flat plate model is used to perform digital simulation feedback on the plate shape of the substrate part, the pore model is arranged on the flat plate model, and the pore model is used to perform digital simulation feedback on the pore structure of the substrate part; S22: constructing a coating digital model based on the substrate digital model to obtain a coating digital model disposed on the substrate digital model; wherein the coating digital model is used to perform digital simulation feedback on the coating portion; S23: taking the coating digital model as a mapping subject, taking the coating effect of the coating digital model as a mapping object, taking the simulation rule of the coating effect of the coating digital model as a mapping relationship, and performing association processing on the mapping subject and the mapping object according to the mapping relationship; S24: performing traversal adjustment and substitution processing of coating setting parameters based on the coating digital model as the mapping subject, so as to obtain the coating effect characteristics of each coating setting parameter corresponding to the traversal adjustment and substitution processing as the mapping object, and using each coating effect characteristic together as an effect evaluation map; wherein the coating effect characteristics are used to describe the coating effect of the coating digital model; S25: Analyze and process the effect evaluation map to determine the optimal coating effect feature in the effect evaluation map, and generate a coating structure scheme for the coating part according to the coating setting parameters corresponding to the optimal coating effect feature.

[0041] Specifically, the design data of the plate shape and pore structure of the titanium-based anode substrate are collected, and a digital model of the substrate is constructed using computer-aided design (CAD) and finite element analysis (FEA) software, such as SolidWorks and ANSYS. According to the plate shape data, a flat plate model of the substrate is established in the CAD software, and digital simulation feedback of the size and geometry is performed. A pore model is added 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.

[0042] More specifically, determine the materials used for the coating and collect data on their physical and chemical properties, superimpose the coating materials on the digital model of the substrate, build a digital model of the coating, ensure that the coating thickness, number of layers and coverage are consistent with the actual design, and use numerical simulation to provide feedback on the adhesion and coverage of the coating on the substrate to optimize the uniformity and performance of the coating.

[0043] 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 estimated 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 based on preset data. This basic model can be used to transform the set parameters to transform the specific form of the coating digital model.

[0044] More specifically, the simulation rules of coating effects are defined, such as the influence of coating thickness on adhesion and electrochemical properties, and the influence of coating on pore blockage. The coating digital model is used as the mapping subject, and a mapping relationship is established according to the simulation rules to generate a coating effect feature description model.

[0045] More specifically, the coating setting parameters are defined, such as coating thickness, coating material ratio, coating process conditions, etc., and optimization algorithms, such as genetic algorithm, particle swarm optimization, etc., are used to traverse various coating setting parameters, calculate and record the corresponding coating effect characteristics, and draw the coating effect characteristics of each coating setting parameter into an effect evaluation map.

[0046] More specifically, the effect evaluation map is analyzed to determine the optimal coating effect characteristics, and the influence of different setting parameters on the coating performance is evaluated. According to the optimal coating effect characteristics, the best coating setting parameters are selected to generate the final coating structure plan of the coating part.

[0047] It can be understood that through the construction of the digital twin model, accurate digital simulation of the substrate and coating parts of the titanium-based anode can be achieved, and a reliable virtual test platform can be provided. The digital model feeds back the real substrate shape and pore structure to ensure the accuracy and effectiveness of the coating simulation. The coating digital model and mapping relationship are used to simulate and optimize the adhesion and coverage effect of the coating on the substrate, improve the uniformity and performance of the coating, and traverse and adjust the coating setting parameters and evaluate the effects to ensure that the selected coating scheme performs best in actual applications. The optimal coating setting parameters are determined to ensure that the coating has good adhesion, electrochemical properties and corrosion resistance, and extend the service life of the titanium-based anode. Through digital simulation and optimization, the functionality and stability of the coating are improved, and the overall performance of the titanium-based anode is improved. The digital twin model and virtual experiments reduce the number and cost of actual experiments, speed up the research and development process, and reduce the trial and error links through simulation feedback and optimization, thereby improving the efficiency of coating design and manufacturing.

[0048] Preferably, the coating digital model is used as a mapping subject, the coating effect of the coating digital model is used as a mapping object, and the simulation rule of the coating effect of the coating digital model is used as a mapping relationship. The step of associating the mapping subject with the mapping object according to the mapping relationship includes: S231: constructing a plurality of coating effect analysis projects based on the coating digital model; wherein the coating effect analysis projects are used to provide feedback on the coating effect of the coating digital model in a specified aspect; S232: Analyzing and processing the correlation between the coating digital model and each of the coating effect analysis items to obtain the correlation between the coating digital model and each of the coating effect analysis items, and using the correlation between the coating digital model and each of the coating effect analysis items as a simulation rule for the coating effect of the coating digital model; S233: taking the coating digital model as the mapping subject, taking the various coating effect analysis items collectively as the mapping object, and taking the simulation rule of the coating effect of the coating digital model as the mapping relationship between the mapping subject and the mapping object; wherein the various coating effect analysis items are used to collectively describe the coating effect of the coating digital model.

[0049] Specifically, according to the expected performance of the coating, several coating effect analysis items are determined, such as the blocking effect 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. More specifically, simulation analysis is performed on the coating digital model under different coating setting parameters, including the simulation test results of each analysis item. Statistical analysis tools or machine learning algorithms, such as multivariate regression analysis and principal component analysis (PCA), are used to analyze the correlation between the coating digital model and each coating effect analysis item. Based on the correlation analysis results, 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 simulation rules for coating effects.

[0050] More specifically, the coating digital model is taken as the mapping subject and the basic model for analysis and optimization. The various coating effect analysis items are taken as mapping objects. These objects are used to evaluate the performance of the coating digital model under different setting parameters. The established coating effect simulation rules are applied to map the coating digital model with the various analysis items to predict and evaluate the coating effect characteristics under different coating setting parameters.

[0051] More specifically, based on the mapping relationship, the digital model of the coating is simulated and calculated to obtain the coating effect characteristics under different setting parameters. The coating setting parameters are traversed and adjusted using an optimization algorithm (such as genetic algorithm, particle swarm optimization), the coating effect characteristics are optimized, and the optimal coating setting parameters are selected.

[0052] It is understandable that through the construction of coating effect analysis projects and correlation analysis, the performance of the coating under different setting parameters can be accurately predicted, reducing the number of actual tests. The simulation rules of coating effects provide a reliable theoretical basis to ensure the accuracy and repeatability of simulation results. Through simulation and optimization, the optimal coating setting parameters can be selected to improve the adhesion, electrochemical properties, corrosion resistance and wear resistance of the coating. The optimized coating design can show better performance and longer service life in actual applications.

[0053] Preferably, the step of performing traversal adjustment and substitution processing of coating setting parameters based on the coating digital model as the mapping subject to obtain the coating effect characteristics of each coating setting parameter traversed, adjusted and substituted as the mapping object, and using each coating effect characteristic as an effect evaluation map comprises: S241: Analyze and process the substrate 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; S242: Substituting several basic setting parameters into the coating digital model as the mapping subject respectively, and performing mapping processing on the coating digital model into which the basic setting parameters are substituted according to the mapping relationship, so as to obtain analysis results of each of the coating effect analysis items as the mapping object, and using the analysis results of each of the coating effect analysis items as the mapping object as the coating effect feature; S243: performing effect evaluation processing on each of the coating effect characteristics to obtain a feature evaluation index of each of the coating effect characteristics; S244: sorting the basic setting parameters according to the index size relationship of the characteristic evaluation index of each coating effect characteristic to obtain a setting parameter characteristic sequence; wherein the setting parameter characteristic sequence includes a plurality of the basic setting parameters arranged in sequence; S245: performing parameter trend analysis on each of the basic setting parameters in the setting parameter feature sequence to obtain parameter trends on each of the basic setting parameters in the setting parameter feature sequence; S246: performing optimization processing on the basis of each of the basic setting parameters according to the parameter trends between each of the basic setting parameters of the setting parameter feature sequence to obtain a plurality of optimized setting parameters; S247: Substituting several kinds of the optimization setting parameters into the coating digital model as the mapping subject respectively, and performing mapping processing on the coating digital model into which the optimization setting parameters are substituted according to the mapping relationship, so as to obtain analysis results of each of the coating effect analysis items as the mapping object, and using the analysis results of each of the coating effect analysis items as the mapping object as the coating effect feature; S248: performing effect evaluation processing on the coating effect characteristics corresponding to each of the optimization setting parameters to obtain a characteristic evaluation index of each of the coating effect characteristics; S249: Arranging 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.

[0054] Specifically, based on the digital model of the titanium-based anode substrate, its physical properties and design parameters are analyzed, and several basic coating setting parameters are determined, such as coating thickness, coating material composition, coating process conditions, etc. Each basic setting parameter describes a specific coating setting method, such as the deposition method of a coating of a specific thickness at a specific temperature.

[0055] More specifically, several basic setting parameters are respectively substituted into the coating digital model, and according to the simulation rules of the coating effect, the coating digital model with the basic setting parameters substituted is mapped 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.

[0056] More specifically, an effect evaluation process is performed on each coating effect feature, and a feature evaluation index is calculated. According to the size of the feature evaluation index, each basic setting parameter is sorted to generate a setting parameter feature sequence. Based on the setting parameter feature sequence, the trend relationship between each basic setting parameter is analyzed to find out the influence of parameter changes on coating effects. According to the parameter trend, the basic setting parameters are optimized to generate a number of optimized setting parameters. The optimized setting parameters are respectively substituted into the coating digital model. According to the simulation rule of the coating effect, the coating digital model substituted with the optimized setting parameters is mapped to obtain the analysis results of each coating effect analysis item. The analysis results of the coating effect analysis item corresponding to the optimized setting parameters are used as the coating effect feature. The coating effect feature of the optimized setting parameters is effect evaluated, and a feature evaluation index is calculated. According to the feature evaluation index, the coating effect features of the basic setting parameters and the optimized setting parameters are arranged to generate an effect evaluation map.

[0057] It is understandable that through precise analysis and adjustment of basic setting parameters and optimized setting parameters, the coating performance can be effectively optimized, and the adhesion, electrochemical properties, corrosion resistance and wear resistance of the coating can be improved. Parameter trend analysis provides a theoretical basis for optimizing setting parameters to ensure the scientificity and rationality of the optimization process. By calculating the characteristic evaluation index, the coating effect under different parameter settings is 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 effect under different parameter settings, which is convenient for 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 improved. The optimized coating design shows better performance in a variety of application scenarios to meet different needs.

[0058] Preferably, the step of pre-treating the substrate portion for coating comprises: S31: performing mechanical polishing on the substrate portion to remove oxides and oil stains on the surface of the substrate portion; S32: performing pickling treatment on the substrate portion to remove impurities on the surface of the substrate portion and produce a uniform oxide film; S33: placing the substrate portion in deionized water for cleaning to passivate the substrate portion, so that the oxide film on the surface of the substrate portion is in a stable state, so as to facilitate subsequent coating setting.

[0059] Specifically, use an appropriate solvent to clean the oil and visible impurities on the surface of the substrate, and use sandpaper, grinding wheel or polishing machine to mechanically polish the surface of the substrate to remove surface oxides and fine oil. During the polishing process, the force and speed should be kept uniform to ensure that the surface is flat and smooth. After polishing, use compressed air to blow away the dust remaining on the surface, and wipe the substrate surface with anhydrous ethanol or other appropriate solvents.

[0060] More specifically, prepare a pickling solution of appropriate concentration (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 for a certain period of time to remove surface impurities and residual oxides. Stirring or slight vibration should be performed during the pickling process to ensure uniform pickling effect. After the pickling is completed, remove the substrate part from the pickling solution and thoroughly rinse it with a large amount of deionized water to remove the residual acid.

[0061] More specifically, the pickled substrate is placed in deionized water for preliminary cleaning to remove the acid and impurities remaining on the surface, and then the substrate is placed in fresh deionized water for a certain period of 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, the substrate is taken out of the deionized water and wiped dry with a dust-free cloth or blown dry with compressed air to ensure that there are no water stains and impurities on the surface.

[0062] It can be understood that mechanical polishing and pickling treatment effectively remove oxides, oil stains and impurities on the surface of the substrate, ensure a tighter bond between the coating and the substrate, and improve the adhesion and durability of the coating. Deionized water cleaning and passivation treatment further improve the cleanliness of the substrate surface and prevent residual impurities from affecting the quality of the coating. The pickling treatment forms a uniform oxide film on the surface of the substrate, providing a good interface state and promoting uniform coverage and adhesion of subsequent coatings. The passivation treatment keeps the oxide film in a stable state, preventing oxide film damage or unevenness during the coating process and ensuring the consistency of coating quality. Through pretreatment, the substrate surface has a good physical and chemical state, ensuring the adhesion and durability of the coating after coating, improving the overall performance of the coating, and the uniform oxide film provides better protection for the coating, enhancing the corrosion resistance and service life of the coating.

[0063] Preferably, the steps of sequentially preparing the guide structures and filling parts of the respective titanium-based coatings on the substrate according to the coating structure scheme to sequentially prepare the respective titanium-based coatings on the substrate include: S41: performing analytical processing on the coating structure scheme to obtain each of the titanium-based coatings on the substrate portion and the arrangement order of each of the titanium-based coatings; S42: preparing a corresponding guide structure on the substrate portion according to the titanium-based coating having the first arrangement order, so as to generate a corresponding guide structure on the substrate portion; S43: performing a coating treatment of a coating material precursor solution on the substrate portion provided with the guide structure, so that the coating material precursor solution is coated on the surface of the substrate portion under the guidance of the guide structure, and performing a heat treatment on the substrate portion after the coating treatment, so as to prepare the corresponding titanium-based coating; S44: Repeat the above steps until the preparation of all the titanium-based coatings is completed.

[0064] Specifically, the coating structure scheme is analyzed to determine the specific composition, thickness, material type and coating sequence of each titanium-based coating on the substrate part. According to the coating structure scheme, the setting sequence of each titanium-based coating is determined, starting from the first coating to be set layer by layer.

[0065] More specifically, according to the requirements of the titanium-based coating that is first set in order, a suitable guide structure material is selected to prepare the guide structure on the substrate part, so that the guide structure is evenly covered on the surface of the substrate to provide a good adhesion interface, and the substrate with the guide structure is appropriately heat treated (such as drying and annealing) to improve the stability and adhesion of the guide structure.

[0066] More specifically, according to the requirements of the coating material, a suitable coating material precursor solution, such as a titanate solution, a titanium oxide solution, etc., is prepared, and the coating material precursor solution is evenly coated on the surface of the substrate provided with a guide structure by spraying, spin coating or dipping, ensuring that the precursor solution is evenly distributed under the guidance of the guide structure, and the coated substrate is heat treated, such as drying, annealing or sintering, to convert the precursor solution into a stable titanium-based coating.

[0067] More specifically, repeat the guiding structure and coating treatment: according to the order in the coating structure scheme, the guiding structure preparation and precursor solution coating treatment of each titanium-based coating are carried out in turn, and the corresponding heat treatment is carried out until the preparation of all titanium-based coatings is completed. After all coatings are prepared, an overall heat treatment is carried out to improve the bonding strength and overall stability of the multi-layer titanium-based coating.

[0068] It can be understood that the guiding structure of each layer of coating ensures the uniform distribution and good adhesion of the coating material on the substrate surface, improves the uniformity and performance of the coating, and the design and optimization of the layered structure make the coating superior in many properties, such as corrosion resistance, mechanical strength and conductivity. Through multiple heat treatment processes, each layer of coating material is fully transformed and stabilized to form a dense and highly adhesive coating structure, which improves the durability and performance stability of the coating. The optimized coating material precursor solution and coating process ensure the high quality and consistency of the coating to meet the needs of different applications.

[0069] Preferably, the method for preparing the corresponding guide structure on the substrate portion is an anodic oxidation technology, a micromachining technology or a chemical vapor deposition technology.

[0070] Specifically, anodizing pretreatment: prepare a suitable electrolyte (such as sulfuric acid, phosphoric acid or oxalic acid solution), adjust the concentration and temperature of the solution, immerse the substrate as the anode in the electrolyte, and pass a constant current or voltage. According to the characteristics of the desired oxide film, control the oxidation time and conditions. After the oxidation is completed, thoroughly wash the substrate with deionized water to remove the residual electrolyte and dry it.

[0071] Specifically, micromachining technology: Similar to anodizing pre-treatment, ensure the cleanliness of the substrate surface. Apply a protective coating to the non-processed area as needed to prevent unnecessary material removal. Select suitable micromachining equipment, such as a micro drill, laser etcher or ion beam processing equipment. Perform precise microstructure processing according to design requirements to prepare the required guide structure. Control processing parameters (such as feed speed, laser power) to achieve the best effect. Remove the protective coating and clean the substrate surface with deionized water.

[0072] Specifically, chemical vapor deposition technology: clean the substrate surface to ensure that there are no pollutants and oxides, preheat the substrate before deposition to improve coating adhesion, select appropriate reaction gas and carrier gas (such as titanium tetrachloride and hydrogen), and adjust the gas flow and ratio. Under high temperature conditions (usually 500°C to 1000°C), place the substrate in the reaction chamber, and the reaction gas reacts chemically on the substrate surface to form a guide structure. Control the deposition time to achieve the desired thickness. After deposition, slowly cool the substrate and wash it with deionized water to remove possible chemical residues.

[0073] It is understandable that anodizing can form a uniform and dense oxide film on the surface of the substrate, increase the surface hardness and corrosion resistance, and by adjusting the oxidation parameters, the pore size and thickness of the oxide film can be controlled, which helps to improve the adhesion of the coating; micromachining technology can prepare high-precision microstructures and guide the uniform deposition of coating materials. The processing technology can be flexibly adjusted to obtain the desired structure according to different design requirements; chemical vapor deposition can form a high-purity guiding structure on the surface of the substrate, providing excellent corrosion resistance and mechanical properties. The coating formed through chemical reaction deposition has good chemical bonding with the substrate, thereby improving the overall coating performance.

[0074] In a second aspect, the present invention provides an electrode processing device for a titanium-based anode, which is used to implement a processing method for a titanium-based anode as described in any one of the first aspects.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
