Description

Technical Field

[0001] The invention belongs to the technical field of quality data analysis of finished products of cobalt-chromium-molybdenum alloy joint castings, and relates to a method for analyzing and processing quality data of finished products of cobalt-chromium-molybdenum alloy joint castings. Background Art

[0002] Cobalt-chromium-molybdenum alloy is a metal material with excellent properties. Its main features include high hardness, good corrosion resistance, wear resistance and good biocompatibility. These characteristics make cobalt-chromium-molybdenum alloy widely used in many fields such as medical, aerospace, and automobile manufacturing. Among them, it is most widely used in the medical field. As one of the main materials for artificial joints, cobalt-chromium-molybdenum alloy joint castings need to meet extremely high quality requirements. This is not only related to the patient's surgical effect and rehabilitation process, but also directly affects the patient's quality of life and long-term health. Therefore, the analysis system for the quality data of cobalt-chromium-molybdenum alloy joint castings is of great significance and role.

[0003] In the prior art, there are also some related solutions involving quality data analysis of castings. For example, the invention patent application for a casting defect prediction method and system based on big data, with Chinese patent publication number CN118095113A, collects key parameters of the casting process, records environmental conditions and raw material characteristics, and organizes the data to obtain real-time casting parameter records. Further, by combining big data technology with computational fluid dynamics dynamic simulation, it can accurately predict the development trend of defects under complex casting conditions, conduct detailed analysis of conditions such as cooling rate and material shrinkage, and accurately identify potential defects in the changing environment of casting production, so as to take effective measures to prevent the formation of defects in the early stage of production. The forward-looking prediction and prevention and control strategy avoids the common post-remediation treatment method in traditional methods, significantly improves the quality of castings, and effectively saves costs and improves production efficiency.

[0004] Although the above scheme proposes some solutions for the quality data analysis of castings, it still has certain limitations: on the one hand, the existing scheme mainly detects and analyzes the development of defects in the casting process, and prevents and controls the defects of castings, but the existing scheme lacks the detection of raw materials for the quality of finished castings, and thus cannot rule out the impact of raw materials on the quality of finished castings.

[0005] On the other hand, the existing scheme ignores the comparative analysis of the quality of the finished cobalt-chromium-molybdenum alloy joint castings with the quality of the finished cobalt-chromium-molybdenum alloy joint castings made by traditional processes, and thus cannot understand the optimization and improvement of the finished cobalt-chromium-molybdenum alloy joint castings compared with the finished cobalt-chromium-molybdenum alloy joint castings prepared by traditional processes, which is not conducive to promoting the application and development of cobalt-chromium-molybdenum alloys in the field of joint castings, nor is it conducive to improving the overall level of the industry. Summary of the invention

[0006] In view of this, in order to solve the problems raised in the above background technology, a method for analyzing and processing the quality data of finished products of cobalt-chromium-molybdenum alloy joint castings is now proposed.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 As shown, the present invention provides a method for analyzing and processing quality data of finished cobalt-chromium-molybdenum alloy joint castings, and the specific steps are as follows: S1. Acquisition of quality data of finished castings: recording the finished cobalt-chromium-molybdenum alloy joint casting to be inspected as the target finished cobalt-chromium-molybdenum alloy joint casting, inspecting it, and acquiring raw material data, appearance data, defect data and mechanical property data of the target finished cobalt-chromium-molybdenum alloy joint casting.

[0021] As a preferred feasible embodiment, the raw material data of the target cobalt-chromium-molybdenum alloy joint casting product includes cobalt content, chromium content and molybdenum content.

[0022] It should be further explained that the reasons for using cobalt content, chromium content and molybdenum content as the raw material data of the target cobalt-chromium-molybdenum alloy joint casting finished product are: (1) Cobalt has good corrosion resistance and high temperature stability and is an indispensable matrix element in the alloy. The addition of chromium can significantly improve the corrosion resistance and hardness of the alloy. It can form a dense oxide film on the surface of the alloy to effectively prevent erosion by external corrosive media. The addition of molybdenum helps to refine the grain structure of the alloy, thereby improving the strength and toughness of the alloy. Molybdenum can also enhance the wear resistance of the alloy, making it exhibit better durability when subjected to friction and wear.

[0023] (2) The casting properties of cobalt-chromium-molybdenum alloy are greatly affected by the alloy composition. A reasonable ratio of cobalt, chromium and molybdenum content helps to obtain good fluidity, filling and solidification properties, thereby ensuring the quality of the casting.

[0024] It needs to be further explained that the specific method of obtaining the cobalt content, chromium content and molybdenum content of the target cobalt-chromium-molybdenum alloy joint casting finished product is: directly detecting the target cobalt-chromium-molybdenum alloy joint casting finished product by X-ray fluorescence spectrometry to obtain the cobalt content, chromium content and molybdenum content of the target cobalt-chromium-molybdenum alloy joint casting finished product.

[0025] The appearance data of the target cobalt-chromium-molybdenum alloy joint casting finished product includes surface roughness, coating thickness and dimensional conformity.

[0026] It is necessary to further explain that the reasons for taking surface roughness, coating thickness and dimensional conformity as the target appearance data of the finished cobalt-chromium-molybdenum alloy joint castings are: (1) Surface roughness directly affects the wear resistance and corrosion resistance of the castings and the matching accuracy with other parts. Rough surfaces are more susceptible to wear and corrosion, reducing the service life of the product.

[0027] (2) For cobalt-chromium-molybdenum alloy joint castings, coatings are usually used to enhance their corrosion resistance and prevent the precipitation of metal ions from causing adverse effects on surrounding tissues. Coatings can also improve the wear resistance of castings and reduce wear caused by friction. Appropriate coating thickness can ensure that the castings maintain stable performance during long-term use.

[0028] (3) Dimensional conformity is one of the important indicators for evaluating the machining accuracy of castings. For cobalt-chromium-molybdenum alloy joint castings that need to be assembled with other parts, their dimensions must be accurate to ensure smooth assembly and the overall performance of the product. The degree of dimensional conformity directly reflects the production process level and quality control capabilities of the castings.

[0029] It needs to be further explained that the specific method of obtaining the surface roughness, coating thickness and dimensional conformity of the target cobalt-chromium-molybdenum alloy joint casting finished product is: using a surface roughness meter to directly measure the target cobalt-chromium-molybdenum alloy joint casting finished product to obtain the surface roughness of the target cobalt-chromium-molybdenum alloy joint casting finished product.

[0030] The eddy current thickness gauge is used to directly measure each measuring point on the surface of the target cobalt-chromium-molybdenum alloy joint casting product to obtain the coating thickness of each measuring point on the surface of the target cobalt-chromium-molybdenum alloy joint casting product. The average coating thickness of the surface measuring points of the target cobalt-chromium-molybdenum alloy joint casting product is further measured, and the average coating thickness is recorded as the coating thickness of the target cobalt-chromium-molybdenum alloy joint casting product.

[0031] It needs to be explained that the method for obtaining the surface measurement points of the target cobalt-chromium-molybdenum alloy joint casting finished product is: dividing the target cobalt-chromium-molybdenum alloy joint casting finished product in the form of a plane grid, and further recording the grid intersections obtained by dividing the plane grid in the target cobalt-chromium-molybdenum alloy joint casting finished product as the surface measurement points of the target cobalt-chromium-molybdenum alloy joint casting finished product.

[0032] The target cobalt-chromium-molybdenum alloy joint casting product is scanned with a 3D scanner to obtain the 3D data of the target cobalt-chromium-molybdenum alloy joint casting product, and further constructed with professional software to obtain a 3D visualization model of the target cobalt-chromium-molybdenum alloy joint casting product, which is then overlapped and compared with the standard 3D visualization model of the target cobalt-chromium-molybdenum alloy joint casting product stored in the information library to obtain the degree of overlap between the 3D visualization model of the target cobalt-chromium-molybdenum alloy joint casting product and the standard 3D visualization model, which is then recorded as the dimensional conformity of the target cobalt-chromium-molybdenum alloy joint casting product.

[0033] The defect data of the target cobalt-chromium-molybdenum alloy joint casting product include the number of cracks, the number of pores and the diameter of each pore, the number of looseness, the area ratio occupied by each looseness, the coordinates of each looseness position and each looseness shape.

[0034] It should be further explained that the reasons for taking the number of cracks, the number of pores and the diameter of each pore, the number of looseness, the area ratio of each looseness, the coordinates of each looseness position and the shape of each looseness as the defect data of the target cobalt-chromium-molybdenum alloy joint casting finished product are: (1) Cracks are one of the common serious defects in castings, and their occurrence is closely related to the stress state inside the casting. The number of cracks is an important indicator to measure the degree of crack defects in castings, which can directly reflect the size and distribution of stress on the casting during solidification and cooling. The more cracks there are, the greater the internal stress of the casting and the lower the structural strength, which has a serious impact on the performance and life of the casting.

[0035] (2) Pores are cavities in the metal that remain in the casting due to the failure of gas to be discharged in time. The number of pores and the diameter of each pore are important parameters for measuring the degree of pore defects in castings. A large number of pores and a large diameter will significantly reduce the density and mechanical properties of the casting, such as tensile strength and yield strength. In addition, pores may also become stress concentration points, accelerating the fatigue failure of castings. Therefore, using the number of pores and the diameter of each pore as defect data is helpful in evaluating the quality and performance of castings.

[0036] (3) Porosity is a tiny hole or void formed in a casting due to shrinkage or gas precipitation during solidification of the molten metal. The number of porosities, the proportion of each porosity area, the coordinates of each porosity position and the shape of each porosity can comprehensively reflect the severity and distribution of the porosity defects in the casting. A large number of porosities and a large proportion of the area occupied indicate that the internal structure of the casting is not dense and the mechanical properties are reduced. At the same time, the location and shape of the porosity may also affect the performance of the casting. For example, porosity located in the key stress-bearing parts of the casting is more likely to cause stress concentration and fatigue failure. Therefore, using these parameters as defect data helps to more accurately evaluate the quality and performance of the casting.

[0037] It needs to be further explained that the specific method for obtaining the number of cracks, the number of pores and the diameter of each pore, the number of looseness, the area ratio of each looseness, the position coordinates of each looseness and the shape of each looseness of the target cobalt-chromium-molybdenum alloy joint casting finished product is: using computer tomography technology to scan and detect the target cobalt-chromium-molybdenum alloy joint casting finished product, to obtain a three-dimensional CT image of the target cobalt-chromium-molybdenum alloy joint casting finished product, directly extracting each crack, each pore and each looseness of the target cobalt-chromium-molybdenum alloy joint casting finished product, and further statistically analyzing the number of cracks, the number of pores and the number of looseness of the target cobalt-chromium-molybdenum alloy joint casting finished product.

[0038] The three-dimensional CT image of the target cobalt-chromium-molybdenum alloy joint casting product is directly analyzed by image analysis software to obtain the diameters of the pores of the target cobalt-chromium-molybdenum alloy joint casting product.

[0039] The three-dimensional CT image of the target cobalt-chromium-molybdenum alloy joint casting product is directly analyzed by image analysis software to obtain the area occupied by each loose area of ​​the target cobalt-chromium-molybdenum alloy joint casting product, and then the area occupied by each loose area of ​​the target cobalt-chromium-molybdenum alloy joint casting product is divided by the total area of ​​the target cobalt-chromium-molybdenum alloy joint casting product stored in the information database, and the quotients obtained are recorded as the proportions of the loose areas of the target cobalt-chromium-molybdenum alloy joint casting product.

[0040] The center point of the three-dimensional CT image of the target cobalt-chromium-molybdenum alloy joint casting product is selected as the coordinate origin, a straight line is drawn horizontally through the coordinate origin as the horizontal axis, a straight line perpendicular to the horizontal axis is drawn through the coordinate origin as the vertical axis, and a straight line vertically perpendicular to the horizontal axis is drawn through the coordinate origin as the Z axis, so as to obtain the three-dimensional coordinate system corresponding to the three-dimensional CT image of the target cobalt-chromium-molybdenum alloy joint casting product, and further use image analysis software to directly analyze the three-dimensional CT image of the target cobalt-chromium-molybdenum alloy joint casting product to obtain the various loose positions of the target cobalt-chromium-molybdenum alloy joint casting product, and then directly obtain the coordinates of the various loose positions of the target cobalt-chromium-molybdenum alloy joint casting product in the three-dimensional coordinate system corresponding to the three-dimensional CT image of the target cobalt-chromium-molybdenum alloy joint casting product.

[0041] Various loose images of the target cobalt-chromium-molybdenum alloy joint casting product are extracted from the three-dimensional CT image of the target cobalt-chromium-molybdenum alloy joint casting product, and further matched with the images of various loose forms stored in the information library to obtain various loose forms of the target cobalt-chromium-molybdenum alloy joint casting product.

[0042] The mechanical property data of the target cobalt-chromium-molybdenum alloy joint casting finished product include strength, toughness, fatigue strength and fatigue life.

[0043] It should be further explained that the reasons for using strength, toughness, fatigue strength and fatigue life as the target mechanical properties of finished cobalt-chromium-molybdenum alloy joint castings are: (1) Strength refers to the ability of a material to resist damage by external forces, usually referring to the maximum ability of a material to resist damage when subjected to external forces such as tension, compression, and bending. For cobalt-chromium-molybdenum alloy joint castings, high strength is the basis for ensuring that they can withstand the weight of the human body and various sports loads during use. Sufficient strength can prevent the joints from breaking or deforming when subjected to stress, thereby ensuring the safety of the patient and the normal function of the joints.

[0044] (2) Toughness refers to the ability of a material to absorb energy without brittle fracture when subjected to impact or sudden loading. In the field of medical implants, toughness is particularly important for joint castings. Because during the human body's movement, joints are subject to a variety of complex and sudden loads. Good toughness can ensure that joints are not easily fractured when impacted, thereby improving their service life and safety.

[0045] (3) Fatigue strength refers to the maximum stress that a material can withstand without damage under an infinite number of alternating loads. For cobalt-chromium-molybdenum alloy joints implanted in the human body for a long time, fatigue strength is an important indicator to measure their durability and reliability. During long-term use, joints will be subjected to continuous and cyclical loads, such as stress generated by walking, running and other exercises. Good fatigue strength can ensure that joints are not prone to fatigue damage during long-term use, thereby extending their service life.

[0046] (4) Fatigue life refers to the number of strain cycles required for a material to produce fatigue failure under cyclic loading. For actual castings, fatigue life is often measured in terms of cycles. Fatigue life is directly related to the service life of cobalt-chromium-molybdenum alloy joint castings and the patient's experience. A longer fatigue life means that the joint can maintain stable performance for a longer period of time, reducing the inconvenience and pain caused to patients by frequent joint replacement. At the same time, a longer fatigue life also helps reduce medical costs and social burdens.

[0047] It should be further explained that the specific method for obtaining the strength, toughness, fatigue strength and fatigue life of the target cobalt-chromium-molybdenum alloy joint casting finished product is: when preparing the target cobalt-chromium-molybdenum alloy joint casting finished product, the strength furnace casting test bar, toughness furnace casting test bar and fatigue furnace casting test bar corresponding to the target cobalt-chromium-molybdenum alloy joint casting finished product are prepared according to the same preparation process. The preparation process of cobalt-chromium-molybdenum alloy joint casting is as follows: Figure 2 shown.

[0048] It should be explained that the furnace casting test bar is a sample manufactured together with the production parts during the metal casting process for the purpose of subsequent quality control and material performance testing. This test bar is usually cast under the same conditions as the actual production castings, so as to reflect the true performance of the batch of materials.

[0049] The strength test bar corresponding to the target cobalt-chromium-molybdenum alloy joint casting finished product is placed on a universal material testing machine, and stretched according to the specified loading speed until it breaks. The tensile force when the strength test bar corresponding to the target cobalt-chromium-molybdenum alloy joint casting finished product breaks is recorded, and it is recorded as the strength of the target cobalt-chromium-molybdenum alloy joint casting finished product.

[0050] The toughness test bar corresponding to the target cobalt-chromium-molybdenum alloy joint casting product is placed on an impact testing machine and impacted until it breaks. The impact force when the toughness test bar corresponding to the target cobalt-chromium-molybdenum alloy joint casting product breaks is recorded, and it is recorded as the toughness of the target cobalt-chromium-molybdenum alloy joint casting product.

[0051] The fatigue furnace-cast test bar corresponding to the target cobalt-chromium-molybdenum alloy joint casting finished product is installed on the fatigue testing machine, and the parameters such as loading frequency, stress ratio, and stress amplitude are set. It is subjected to cyclic loading until it breaks, and the maximum stress and the number of cycles when the fatigue furnace-cast test bar corresponding to the target cobalt-chromium-molybdenum alloy joint casting finished product breaks are recorded. Further, the maximum stress when the fatigue furnace-cast test bar corresponding to the target cobalt-chromium-molybdenum alloy joint casting finished product breaks is recorded as the fatigue strength of the target cobalt-chromium-molybdenum alloy joint casting finished product, and the number of cycles when the fatigue furnace-cast test bar corresponding to the target cobalt-chromium-molybdenum alloy joint casting finished product breaks is recorded as the fatigue life of the target cobalt-chromium-molybdenum alloy joint casting finished product.

[0052] The present invention obtains raw material data, appearance data, defect data and mechanical property data of the target cobalt-chromium-molybdenum alloy joint casting product, thereby providing data support for subsequent analysis of raw material compliance, appearance compliance, defect data and mechanical property data, which is helpful to ensure product quality, improve production efficiency, reduce production costs and optimize product design, etc., and has important significance and benefits.

[0053] S2. Analysis of casting finished product quality data: Analyze the raw material conformity, appearance conformity, defects and mechanical properties of the target cobalt-chromium-molybdenum alloy joint casting finished products, and provide feedback and process them.

[0054] It needs to be further explained that the specific operations of processing the target cobalt-chromium-molybdenum alloy joint casting finished product include: if the raw materials of the target cobalt-chromium-molybdenum alloy joint casting finished product are not compliant, then further re-verification is carried out on it. If the result is still that the raw materials are not compliant, then use is stopped immediately, and feedback is given, and the supplier is contacted for return or exchange or other remedial measures.

[0055] If the appearance of the target cobalt-chromium-molybdenum alloy joint casting product is not in compliance with the appearance, it will be further verified again. If the result is still not in compliance with the appearance, the unqualified position will be marked, and rework, repair or scrapping will be selected according to the actual situation.

[0056] If the target cobalt-chromium-molybdenum alloy joint casting product has defects, it will be scrapped directly, and further combined with the casting process of the target cobalt-chromium-molybdenum alloy joint casting product, the reasons for the defects will be analyzed, and corresponding improvement measures will be taken.

[0057] If the mechanical properties of the target cobalt-chromium-molybdenum alloy joint casting product are not in compliance with the requirements, it will be directly scrapped, and the reasons for the non-compliance of the mechanical properties will be analyzed in combination with the casting process of the target cobalt-chromium-molybdenum alloy joint casting product, and corresponding improvement measures will be taken.

[0058] As a preferred feasible embodiment, the raw materials of the target cobalt-chromium-molybdenum alloy joint casting finished product meet the requirements, and the specific analysis method includes: extracting the cobalt content, chromium content and molybdenum content of the target cobalt-chromium-molybdenum alloy joint casting finished product, and recording them as , analyze the raw material conformity of the target cobalt-chromium-molybdenum alloy joint casting finished product ,in They are the standard cobalt content, standard chromium content and standard molybdenum content of the target cobalt-chromium-molybdenum alloy joint casting finished product extracted from the information library respectively.

[0059] The raw material compliance of the target cobalt-chromium-molybdenum alloy joint casting finished product is compared with the set raw material compliance threshold. If the raw material compliance of the target cobalt-chromium-molybdenum alloy joint casting finished product is less than the raw material compliance threshold, the raw material compliance of the target cobalt-chromium-molybdenum alloy joint casting finished product is recorded as raw material non-compliance; otherwise, the raw material compliance of the target cobalt-chromium-molybdenum alloy joint casting finished product is recorded as raw material compliance.

[0060] Specifically, the set raw material compliance threshold is 3. If the raw material compliance of the target cobalt-chromium-molybdenum alloy joint casting finished product is 3, it means that the cobalt content, chromium content and molybdenum content of the target cobalt-chromium-molybdenum alloy joint casting finished product are exactly the same as the corresponding standard cobalt content, standard chromium content and standard molybdenum content, respectively, which further indicates that the raw material compliance of the target cobalt-chromium-molybdenum alloy joint casting finished product is raw material compliance.

[0061] As a preferred feasible embodiment, the appearance conformity of the target cobalt-chromium-molybdenum alloy joint casting finished product is analyzed in a specific manner including: extracting the surface roughness, coating thickness and dimensional conformity of the target cobalt-chromium-molybdenum alloy joint casting finished product, which are recorded as , analyze the appearance conformity of the target cobalt-chromium-molybdenum alloy joint casting finished product ,in To set the target surface roughness threshold of the finished Co-Cr-Mo alloy joint casting, For the standard coating thickness of the target Co-Cr-Mo alloy joint casting finished product extracted from the information library, is the allowable difference between the set coating thickness and the standard coating thickness, To set the target dimensional conformity threshold for finished cobalt-chromium-molybdenum alloy joint castings.

[0062] As a specific feasible example, the target surface roughness threshold of the cobalt-chromium-molybdenum alloy joint casting product is set to 0.01 μm, and the surface roughness of the target cobalt-chromium-molybdenum alloy joint casting product should be as low as possible to reduce friction, improve wear resistance and biocompatibility. The surface roughness threshold is then set to 0.01 μm to achieve a super-mirror effect and reduce the risk of wear and foreign body reaction.

[0063] The set target cobalt-chromium-molybdenum alloy joint casting finished product size compliance threshold is 0.9999, indicating that 99.99% of the target cobalt-chromium-molybdenum alloy joint casting finished product size meets the requirements, to ensure that it can fit well with adjacent bones and tissues after implantation in the human body, avoiding problems such as loosening and dislocation.

[0064] The appearance quality of the target cobalt-chromium-molybdenum alloy joint casting finished product can be obtained by obtaining the raw material quality of the target cobalt-chromium-molybdenum alloy joint casting finished product.

[0065] It needs to be further explained that the specific method of obtaining the appearance compliance of the target cobalt-chromium-molybdenum alloy joint casting finished product is: comparing the appearance compliance of the target cobalt-chromium-molybdenum alloy joint casting finished product with the set appearance compliance threshold; if the appearance compliance of the target cobalt-chromium-molybdenum alloy joint casting finished product is less than the appearance compliance threshold, the appearance compliance of the target cobalt-chromium-molybdenum alloy joint casting finished product is recorded as appearance compliance; otherwise, the raw material compliance of the target cobalt-chromium-molybdenum alloy joint casting finished product is recorded as appearance non-compliance.

[0066] As a preferred feasible embodiment, the defect situation of the target cobalt-chromium-molybdenum alloy joint casting finished product, and its specific analysis method includes: extracting the number of cracks of the target cobalt-chromium-molybdenum alloy joint casting finished product, if it is not 0, then recording the defect situation of the target cobalt-chromium-molybdenum alloy joint casting finished product as a defect.

[0067] If it is 0, the porosity defect level and the looseness defect level of the target cobalt-chromium-molybdenum alloy joint casting product are further analyzed.

[0068] If both the pore defect level and the porosity defect level of the target cobalt-chromium-molybdenum alloy joint casting finished product meet the requirements, the defect situation of the target cobalt-chromium-molybdenum alloy joint casting finished product shall be recorded as no defect; if one of the pore defect level and the porosity defect level of the target cobalt-chromium-molybdenum alloy joint casting finished product does not meet the requirements, the defect situation of the target cobalt-chromium-molybdenum alloy joint casting finished product shall be recorded as defective.

[0069] As a preferred feasible embodiment, the pore defect level of the target cobalt-chromium-molybdenum alloy joint casting product is specifically analyzed by: extracting the number of pores and the diameter of each pore of the target cobalt-chromium-molybdenum alloy joint casting product, respectively recorded as ,in , The number of each pore is used to analyze the pore defect indicators of the target cobalt-chromium-molybdenum alloy joint casting product. ,in They are respectively the allowable number of pores and the allowable pore diameter extracted from the information database under the conditions that do not affect the use of the target cobalt-chromium-molybdenum alloy joint casting products.

[0070] The porosity defect existence index of the target cobalt-chromium-molybdenum alloy joint casting product is matched with the porosity defect existence index range corresponding to each porosity defect grade stored in the information library to obtain the porosity defect grade of the target cobalt-chromium-molybdenum alloy joint casting product.

[0071] As a preferred feasible embodiment, the porosity defect level of the target cobalt-chromium-molybdenum alloy joint casting product is specifically analyzed by: extracting the porosity number and the area ratio of each porosity of the target cobalt-chromium-molybdenum alloy joint casting product, respectively recorded as ,in , The loose position coordinates of the target cobalt-chromium-molybdenum alloy joint casting product are extracted and matched with the corresponding scores of the reference loose position coordinates stored in the information database to obtain the corresponding scores of the loose position coordinates of the target cobalt-chromium-molybdenum alloy joint casting product. , extract the various loose forms of the target cobalt-chromium-molybdenum alloy joint casting products, match them with the corresponding scores of the reference loose forms stored in the information database, and obtain the corresponding scores of the various loose forms of the target cobalt-chromium-molybdenum alloy joint casting products .

[0072] Analysis of the indicators of loose defects in the finished products of cobalt-chromium-molybdenum alloy joint castings IndexI = { tanh [ ∑ j = 1 m ( K 0 K j + 1 + PosG j + FormG j ) ] , m ≤ m 0 1 , m > m 0 ,in They are respectively the allowable porosity number and the allowable porosity area ratio extracted from the information database without affecting the use of the target cobalt-chromium-molybdenum alloy joint casting products.

[0073] The porosity defect level of the target cobalt-chromium-molybdenum alloy joint casting product can be obtained by the specific method of obtaining the porosity defect level of the target cobalt-chromium-molybdenum alloy joint casting product.

[0074] It needs to be further explained that the specific method of obtaining the loose defect level of the target cobalt-chromium-molybdenum alloy joint casting product is: matching the loose defect existence index of the target cobalt-chromium-molybdenum alloy joint casting product with the loose defect existence index range corresponding to each loose defect level stored in the information database to obtain the loose defect level of the target cobalt-chromium-molybdenum alloy joint casting product.
