ABSTRACT: The state of the art of deposition of wear resistant coatings on cutting tools and cold forming tools is briefly reported. Some the PVD arc coatings developed and deposited at the Institute of Advanced Manufacturing Technology (IAMT) are discussed. The coatings structures are presented and the multilayer architecture in micro and nano-scale is revealed. Some results of the PVD arc coatings developed and deposited at the Institute are presented. These include nanostructured and multilayer coatings, which indicate the possibility of considerable increase in tool lives. The current trends in development of the coatings are briefly discussed.

KEYWORDS: coatings, arc plasma PVD method, tools
