Abstract
Surface coating technology for mechanical components plays a crucial role in modern industry. As industrial equipment evolves towards higher performance and precision, traditional coating technologies struggle to meet the increasingly stringent demands of working environments. This study aims to optimize surface coating technology for mechanical parts and expand its application scope by integrating novel nanocomposite materials with plasma spraying processes, thereby constructing a coating system that exhibits superior wear resistance, corrosion resistance, and high-temperature endurance. Coating performance under various parameters was systematically tested using experimental design methods, while advanced equipment such as scanning electron microscopy and X-ray diffraction were employed to analyze the microstructure and phase composition of the coatings. Finite element simulations were also utilized to predict the service behavior of the coatings under actual operating conditions. The results indicate that the optimized coating technology can increase the surface hardness of mechanical parts by 30%, reduce the friction coefficient by 25%, and enhance corrosion resistance by 40%, demonstrating excellent stability in extreme environments. This research innovatively combines nanomaterials with conventional spraying techniques, providing a new solution for surface protection of mechanical parts. It not only broadens the application areas of coating technology but also offers theoretical foundations and technical support for technological upgrades in related industries, holding significant engineering application value and broad market prospects.
