    Abstract

    The microstructure of PVD TiN coated tools steels composites has been investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). It was found that the microstructure of the coatings consists of a dense fibrous structure typical of a zone T structure. When the composite material is subjected to a rolling contact test the failure is mainly initiated at the interface with crack grow in the coating parallel to the surface. The interfacial failure stress is closely associated with the coating-substrate bonding conditions.
