Abstract
A cutting tool is provided, at least in certain areas, with a carbonitride coating, which acts to reduce friction and as a wear-protective layer. The coating is applied by means of a modified PVD process in that, for creating the carbonitride layer, carbon and nitrogen in the form of gas are introduced into the reaction chamber, and one or several ion sources are continued to be operated to form plasma.
