Abstract

This research synthesizes recent advancements in surface coating technologies for enhancing material performance. It covers arange of deposition methods including PVD, CVD, plasma spraying, sputtering, laser cladding, HVOF, and PECVD for DLC coatings. The studies investigate improvements in wear resistance, corrosion protection, tribological performance, and friction reduction. Functional gradient and composite coatings developed via powder metallurgy are also explored. The collective findings emphasize the importance of tailored coating design and optimized deposition processes for extending component lifespan and functionality in demanding applications, including mitigation strategies for tribocorrosion
