Abstract:
Modern automotive designs are needed to increase mechanical and thermal loads that have longer lifespans and are lighter. The power transmissions and motors often use low-friction hard coatings to prevent wear and reduce friction. The Cr-doped graphite-like carbon method is employed for evaluating coating friction and responses to chromium-doped graphite-like carbon (Cr-GLC) under lubrication. Cr-GLC coatings and chromium-doped diamond-like carbon (Cr-DLC) coatings are arranged using physical vapor deposition (PVD) and plasma-enhanced chemical vapor deposition (PECVD), respectively. ; The results have demonstrated in comparison to the dry friction coefficient, the friction coefficient under lubrication conditions has been reduced by 40%. Due to its excellent frictional physicochemical properties and compact microstructure, Cr-DLC has an optimum tribological resistance that is significantly higher than that of Cr-GLC. Viscosity, corrosivity, and coating microstructure are used to measure the impact of composite elements. The most ideal characteristics of the Cr-GLC coating are attributed to the non-reaction of additives in oil with friction surfaces.
