Abstract
Coating for a cutting tool comprises Ti nitride and 10-30 wt.% Cr nitride; or Ti nitride and (in wt.%): Al nitride 3-18, Mo nitride 2-8, Cr nitride 2-10 and Si nitride 0.5-10, uniformly distributed throughout the coating. The coating is applied on tools used esp. for machining and cutting stainless steels and heat-resistant alloys; the coating exhibits high wear resistance. The coating may be deposited on the tool substrate surface using any suitable method e.g. cathodic sputtering in an N2 atmos. from a suitable Ti alloy cathode- or by metallic plasma techniques, etc.
