Description

Technical Field

[0001] This application relates to the field of product performance evaluation technology, and in particular to a method, apparatus, computer equipment, storage medium and computer program product for quantitative comprehensive evaluation of the environmental adaptability of protective coatings. Background Technology

[0002] Equipment inevitably suffers from corrosion from various environmental factors throughout its entire service life. This is especially true for military equipment with long service times and harsh operating environments, where corrosion is more severe. Corrosion reduces the equipment's environmental adaptability and, in severe cases, affects its lifespan and reliability. Applying protective coatings to the equipment surface is an effective way to improve its corrosion resistance. However, the protective ability of these coatings varies depending on their manufacturing process, the substrate, and the expected service environment of the equipment. Therefore, conducting environmental adaptability tests on protective coatings has become a primary means of optimizing coating processes and evaluating the corrosion resistance of equipment.

[0003] Environmental adaptability tests of protective coatings are affected by uncertainties such as test errors, sample dispersion, and test environment. The test results of performance indicators of different protective coatings often change over time in an intertwined manner. The advantageous performance indicators of each protective coating are also different. However, a single performance indicator cannot fully reflect the adaptability level of the protective coating in complex environments. The comprehensive evaluation results based on multiple performance indicators are affected by the subjective consciousness and personal experience of the testers, and there is a lack of objective quantitative comprehensive evaluation methods. Therefore, the evaluation of the environmental adaptability of protective coatings is inaccurate. Summary of the Invention

[0030] If the sum of the target correlation coefficients is less than or equal to a first preset value, then the value of the weight coefficient is determined to be a second preset value;

[0031] If the sum of the target correlation coefficients is greater than the first preset value, then the ratio is determined as the weighting coefficient, wherein the ratio is the ratio of the sum of the target correlation coefficients to the sum of the plurality of correlation coefficients.

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0055] In one embodiment, such as Figure 1 As shown, a quantitative comprehensive evaluation method for the environmental adaptability of protective coatings is provided. This embodiment illustrates the application of this method to a terminal. It is understood that this method can also be applied to a server, and further to a system including both a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0056] S101. Obtain the protective coating to be processed.

[0057] The protective coating to be treated can be the same type of protective coating under different environmental and maintenance conditions, or it can be different protective coatings under specific environmental conditions. For example, different maintenance conditions include maintenance A (cleaning the protective coating with cleaning agent A for 1 month), maintenance B (cleaning the protective coating with cleaning agent B for 1 month), and maintenance C (not cleaning the protective coating); different environmental conditions include marine atmospheric environment, plateau environment, extreme cold environment, desert environment, etc.

[0058] S102. Determine the initial performance indicators of the protective coating to be treated.

[0059] Performance indicators are parameters used to evaluate the performance of protective coatings. Initial performance indicators are multiple performance indicators corresponding to the protective coating to be treated. For example, initial performance indicators may include appearance rating, appearance morphology of scratched parts, adhesion, total color difference, gloss loss rate, hardness, and low-frequency impedance.

[0060] Specifically, the initial performance metrics can be represented by the set X = {x} ijkl} represents the formula, where i = 1, 2, ..., P, j = 1, 2, ..., M, k = 1, 2, ..., Q, l = 1, 2, ..., N, P is the number of types of protective coatings to be treated, M is the number of time points used to characterize the initial performance indicators, Q is the number of initial performance indicators, N is the number of samples measured for each type of protective coating to be treated, and x is the number of samples measured for each time. ijkl This represents the measured value of the k-th initial performance index of the l-th sample of the i-th type of protective coating at time j.

[0061] S103. Normalize the initial performance indicators to obtain normalized indicators.

[0062] Normalized indices are dimensionless data obtained by converting the initial performance indices of the protective coating to be treated across multiple distribution ranges into the same range. Normalization is the process of obtaining normalized indices.

[0063] Before data normalization, it is necessary to consider the quality of the sample as represented by the size of the performance index, so that the size of the normalized data after conversion is positively correlated with the sample quality.

[0064] Specifically, the server first determines the average performance index of each type of protective coating at different preset time points based on the protective coating to be processed and the initial performance index. Then, the server determines the maximum and minimum index of each average performance index and determines the target difference based on the difference between the maximum and minimum indexes. Finally, the server determines the normalized index based on the relationship between the average performance index and the quality of the protective coating, the average performance index, the maximum index, the minimum index, and the target difference.

[0065] S104. The comprehensive performance index is obtained by weighted averaging the normalized indices based on the protective coating to be treated.

[0066] The comprehensive performance index is a performance index obtained by normalizing and weighted averaging multiple initial performance indices of the same protective coating under different environmental and maintenance conditions or multiple protective coatings under specific environments.

[0067] Specifically, the server determines multiple target correlation coefficients corresponding to the target performance index at the target preset time point based on multiple preset time points, the protective coating to be processed, and normalized indicators. Then, the server calculates the sum of multiple correlation coefficients corresponding to the remaining performance indicators in the initial performance index. Next, the server determines the weight coefficients corresponding to the target performance index based on the sum of multiple target correlation coefficients and the sum of multiple correlation coefficients. Finally, the server calculates the comprehensive performance index by weighted averaging the normalized indicators based on the weight coefficients.

[0068] S105. Evaluate the environmental adaptability of the protective coating to be treated based on comprehensive performance indicators.

[0069] The comprehensive performance index is used to comprehensively evaluate the environmental adaptability of the protective coating. The higher the comprehensive performance index, the better the environmental adaptability of the protective coating. For example, if the comprehensive performance index B (protective coating in environment B) > comprehensive performance index A (protective coating in environment A) > comprehensive performance index C (protective coating in environment C), it means that the protective coating has the best adaptability to environment B and the worst adaptability to environment C.

[0070] In the aforementioned quantitative comprehensive evaluation method for the environmental adaptability of protective coatings, the server first acquires the protective coating to be treated, then determines the initial performance indicators of the protective coating, followed by normalization of the initial performance indicators to obtain normalized indicators, and then calculates a comprehensive performance indicator by weighted averaging of the normalized indicators based on the protective coating to be treated. Finally, the environmental adaptability of the protective coating to be treated is evaluated based on the comprehensive performance indicator. The method provided in this application processes multiple performance indicators of protective coatings in different environments into a comprehensive performance indicator, which can improve the accuracy of the evaluation of the environmental adaptability of protective coatings.

[0071] In some embodiments, normalizing the initial performance index to obtain a normalized index includes: determining the average performance index of each type of protective coating at different preset time points based on the protective coating to be treated and the initial performance index; determining the maximum and minimum average performance index; and normalizing the average performance index based on the maximum, minimum, and average performance index to obtain a normalized index.

[0072] In this step, the average performance index is the average of the target performance index of each protective coating to be treated at each time point. The target preset time point is a time point selected from multiple time points for testing the initial performance index of the protective coating to be treated.

[0073] Specifically, if the same performance index of N samples of each type of protective coating follows a normal distribution at the same time point, then the average performance index is as follows:

[0074]

[0075] In the formula, This represents the average value of the k-th performance index of the i-th protective coating at time j.

[0076] The average performance indicators are treated as a set, and the maximum and minimum values ​​in the set are taken. That is, the maximum value of the k-th performance indicator is obtained from the average performance indicators of the P types of protective coatings at M time points. and minimum value in:

[0077]

[0078]

[0079] The method provided in this step converts the initial performance indicators of the protective coating to be treated, which are in different distribution ranges, into dimensionless data in the same range, i.e., into normalized indicators, which is beneficial for comprehensive evaluation of the performance indicators of different distribution ranges.

[0080] In some embodiments, a normalized index is obtained by normalizing the maximum index, the minimum index, and the average performance index, including: determining a target difference based on the difference between the maximum index and the minimum index; obtaining the relationship between the average performance index and the quality of the protective coating; and determining the normalized index based on the relationship, the average performance index, the maximum index, the minimum index, and the target difference.

[0081] In this step, the quality of the protective coating is a direct reflection of the initial performance index value. The relationship between the average performance index and the quality of the protective coating includes positive and negative correlations. When the relationship is positive, the larger the average performance index, the better the quality of the protective coating. When the relationship is negative, the larger the average performance index, the worse the quality of the protective coating.

[0082] Specifically, the expression for the target difference is as follows:

[0083]

[0084] The method provided in this step determines a normalized index based on the different relationships between average performance indicators and the quality of the protective coating, so that the relationship between all indicators and quality remains consistent.

[0085] In some embodiments, determining a normalized index based on the relationship, average performance index, maximum index, minimum index, and target difference includes: if the relationship is positively correlated, determining a normalized index based on the average performance index, minimum index, and target difference; if the relationship is negatively correlated, determining a normalized index based on the average performance index, maximum index, and target difference.

[0086] In this step, if the relationship between the average performance index and the quality of the protective coating is positively correlated, the normalized data corresponding to the initial performance index of the protective coating to be treated can be calculated by the following formula:

[0087]

[0088] If the relationship between the average performance index and the quality of the protective coating is negatively correlated, the normalized data corresponding to the initial performance index of the protective coating to be treated can be calculated by the following formula:

[0089]

[0090] The normalized index Y is the normalized data set, i.e.

[0091] Y = {y ijk}, (i=1,2,...,P, j=1,2,...,M, k=1,2,...,Q)

[0092] The method provided in this step determines a normalized index based on the different relationships between average performance indicators and the quality of the protective coating, making the determined normalized index more accurate.

[0093] In some embodiments, a comprehensive performance index is obtained by weighted averaging of normalized indices based on the protective coating to be treated, including: determining a target performance index from the initial performance indices; obtaining multiple preset time points; determining multiple target correlation coefficients corresponding to the target performance index at the target preset time points based on the multiple preset time points, the protective coating to be treated, and the normalized indices; determining the weight coefficients corresponding to the target performance index based on the sum of the multiple target correlation coefficients; and calculating the comprehensive performance index by weighted averaging of the normalized indices based on the weight coefficients.

[0094] In this step, the target performance index is a performance index determined from the initial performance index. The preset time point refers to the preset time point of multiple test protective coating target performance indices. The target correlation coefficient is used to characterize the correlation between the target performance index and other performance indices in the initial performance index. The weight coefficient is used to characterize the weight of the target performance index in all initial performance indices.

[0095] Specifically, the target correlation coefficient is shown in the following formula:

[0096]

[0097] In the formula,

[0098]

[0099] z k ={z k1 ,...z ks}={y 11k ,...,y P1k ,y 12k ,...,y P2k ,y 1Mk ...,y PMk},(k=1,2,...,Q,s=P·M)

[0100] The sum of the target correlation coefficients is shown in the following formula:

[0101]

[0102] The comprehensive performance index corresponding to the target performance index of the protective coating to be treated is shown in the following formula:

[0103]

[0104] In the formula, a k These are the weighting coefficients.

[0105] The comprehensive performance index can also be represented in the form of a set: D = {d ij}

[0106] The method provided in this step calculates a comprehensive performance index based on the target correlation coefficient, which can comprehensively evaluate the environmental adaptability of the protective coating.

[0107] In some embodiments, determining the weight coefficient corresponding to the target performance index based on the sum of multiple target correlation coefficients includes: calculating the sum of multiple correlation coefficients corresponding to the remaining performance indexes in the initial performance indexes, wherein the remaining performance indexes are the performance indexes in the initial performance indexes excluding the target performance index; if the sum of target correlation coefficients is less than or equal to a first preset value, then determining the value of the weight coefficient to be a second preset value; if the sum of target correlation coefficients is greater than the first preset value, then obtaining a ratio and determining it as the weight coefficient, wherein the ratio is the ratio of the sum of target correlation coefficients to the sum of multiple correlation coefficients.

[0108] In this step, the weighting coefficients can be expressed by the following formula:

[0109]

[0110] In the formula, R i Let be the correlation coefficient corresponding to any performance index.

[0111] Specifically, when the sum of the target correlation coefficients R k When the weighting coefficient a is less than or equal to the first preset value of 0, k The sum of the target correlation coefficients R is equal to the second preset value of 0. k When the sum of the target correlation coefficients is greater than the first preset value of 0, the ratio of the sum of the target correlation coefficients to the sum of multiple correlation coefficients is used as the weighting coefficient 'a'. k .

[0112] In this step, the weighting coefficients are determined based on the sum of the target correlation coefficients, making the determined weighting coefficients more objective.

[0113] In one embodiment, (1) a natural environment test was conducted on a certain coating system, and tests were conducted under three maintenance conditions: no cleaning, cleaning agent A, and cleaning agent B (corresponding to i = 1, 2, 3). Performance index data of the coating sample under different maintenance conditions for 1 month, 3 months, and 6 months (corresponding to j = 1, 2, 3) were obtained. The performance indexes include the appearance rating, appearance morphology of scratched parts, adhesion, total color difference, gloss loss rate, hardness, low-frequency impedance, and other performance indexes. Figures 2-8 As shown.

[0114] (2) Perform data preprocessing on all performance index observations to obtain the normalized index Y.

[0115] According to the normalized index calculation method provided by the technical solution of this invention, the appearance rating, scratched part appearance morphology, and adhesion index are the same under the three conditions, making it impossible to distinguish the quality of the coating. The normalized calculation results are all 0 / 0, which are recorded as NOT numbers and automatically ignored in subsequent calculations. The remaining normalized index Y is as follows:

[0116] Total color difference:

[0117]

[0118] Loss of light rate:

[0119]

[0120] hardness:

[0121]

[0122] Low-frequency impedance:

[0123]

[0124] Among them, Y s ,Y g ,Y y ,Y z The element in the i-th row and j-th column represents the normalized value of the performance index detected at time j for the i-th maintenance condition.

[0125] (3) Calculate the comprehensive performance index D based on the normalized index:

[0126] 1) Calculate the weighting coefficients, see Table 1. Table 1 shows the results of the correlation coefficient and weighting coefficient calculations;

[0127] Table 1

[0128]

[0129] 2) Calculate the comprehensive index D

[0130]

[0131] The element in the i-th row and j-th column represents the comprehensive index of the i-th maintenance condition at the j-th time point.

[0132] (4) Optimize maintenance conditions based on comprehensive index D: The larger the normalized index, the better the quality of the test piece. Therefore, the larger the index D, the better the maintenance conditions.

[0133] As can be seen from index D, cleaning agent A has the best overall evaluation of maintenance conditions.

[0134] from Figures 2-8 As can be seen, the three performance indicators—total color difference, hardness, and low-frequency impedance—all exhibited cross-coupling changes over time, affecting the evaluation results of individual indicators and causing difficulties in the comprehensive evaluation.

[0135] Table 2 shows the comparison results of individual performance indicators and the comprehensive evaluation results of the technical solution of this invention. It can be seen that: if evaluated based on individual performance indicators of the test pieces, the appearance rating, the appearance morphology of the scratched parts, and the adhesion are all the same and cannot be distinguished; if evaluated based on total color difference and low-frequency impedance, the maintenance conditions of cleaning agent B are better; if evaluated based on hardness and gloss loss rate, the maintenance conditions of cleaning agent A are better. The evaluation results also differ at different times. Therefore, it is not possible to objectively select which maintenance condition is better based on a single indicator.

[0136] According to the technical solution of this invention, a comprehensive index value is obtained by integrating multiple performance indicators, and consistent conclusions can be drawn at different times. A comparison of the evaluation results of single indicators and comprehensive indicators is shown in Table 2:

[0137] Table 2

[0138]

[0139] To further illustrate the advantages of the weighting coefficient calculation method of this invention, equal weighting coefficients were selected, meaning all performance indicators have the same importance, and a comprehensive index calculation was performed. The results are shown below. Figure 10 The results of the technical solution of this invention are shown in [the figure]. Figure 9 The significant advantages of this invention patent can be seen in the comparison.

[0140] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows.
