Elastic and plastic work of indentation as a characteristic of wear behavior for cutting tools with nitride PVD coatings

The chemical and phase composition as well as the structural characteristics of TiN-based PVD versus the nitrogen pressure used during deposition coatings were analyzed using AES and XRD methods. Also the friction and wear properties of the coatings were established under different wear conditions. Using these results a relation between the TiN PVD coating's wear resistance and its ability to dissipate the energy of plastic deformation as well …
