Research on Protective Coating Optimization Technology Based on Comprehensive Evaluation Results of Multiple Parameters
To a certain extent,the quality of protective coating determines whether avionics equipment can safely serve in a specific environment for a long time.Therefore,optimizing the best protective coating according to the characteristics of the service environment has practical significance for improving the adaptability of equipment environment.Based on the results of damp heat test and salt spray test,the optimization method of environmental adaptability of protective coatings for avionics equipment is elaborated.Firstly,the initial performance parameters of protective coatings is selected.Then,the environmental test of protective coatings is carried out,and according to the test results and the qualification criteria of coatings,the optimization of single performance parameters is carried out.Finally,a comprehensive evaluation of several qualified single performance parameters is carried out by principal component analysis to obtain the final optimized coating.This innovative"best in best"optimization working method is suitable for the optimization of the results of natural environment test and various laboratory environmental tests of protective coating system.
