Nanostructured multilayer coatings on cemented carbide and high speed steel cutting tools

The state of the art of deposition of wear resistant coatings on cemented carbide and high speed steel cutting tools is presented with special regard to new possibilities in this field. On the ground of some results of research carried out at the Institute of Advanced Manufacturing Technology on the PVD arc multilayer nanostructured and superlattice coatings development was shown that the obtained coatings can contribute to the tool lives increase.
