Abstract
The study presents tribological evaluations of TiAlN, AlTiN, AlCrN, and TiSiN coatings under boundary lubrication conditions using a tribometer. Results show significant reductions in average friction coefficients compared to uncoated tungsten carbide (0.2436). TiSiN exhibited the lowest friction coefficient (0.2111), highlighting its superior performance. Optical microscopy and profilometry revealed that coatings like TiSiN also minimized surface roughness and wear tracks, indicating enhanced wear resistance. Coatings reduced friction but increased wear on counterparts. This study underscores the coatings pivotal role in industrial applications, balancing friction reduction with wear enhancement.
