摘要

This study examines the stress distribution of wear-resistant conductive coatings on the surface of aircraft wing attachment elastic plates under large deformation conditions through finite element simulation. The influence of different types of metal microparticles, their volume fractions, and coating thickness on coating performance was analyzed. The results demonstrate that the addition of iron microparticles significantly enhances the tensile strength of the coating, but higher proportions lead to stress concentration. In contrast, coatings with titanium microparticles exhibit superior stress dispersion capabilities. The coating thickness has a significant impact on tensile strength, with thicker coatings potentially causing stress concentration and increasing the risk of delamination under large deformation conditions. These findings provide a theoretical foundation for the optimization design of wear-resistant conductive coatings under complex loading conditions.
