In this project, the tribological properties of a few selected PVD coatings have been compared. The microstructure and wear mechanisms of the coatings were extensively investigated using cross-sectional transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Some of the results have been published elsewhere. In this paper, we present the tribological properties and wear mechanisms of a multilayer coating TiAlN/CrN and a multicomponent coating TiAlCrN, and compare these with commercial coatings TiN and CrN.
