FIELD: metal working, namely processes for applying wear resistant multi-layer coatings onto cutting tools. ^ SUBSTANCE: method comprises steps of vacuum-plasma deposition of coating layers. According to invention are applied: lower layer of titanium compound and metal alloyed with aluminum; upper layer of titanium nitride or carbonitride and metal; intermediate layer of upper layer material alloyed with aluminum. Silicon, chrome, molybdenum or zirconium is used as metal. Layers of coatings are applied by means of three built-up cathodes arranged horizontally in the same plane. Two cathodes are arranged mutually opposite and they are made of titanium and used metal, third cathode is made of titanium and aluminum. ^ EFFECT: increased adhesion and cohesion strength of layers with base material, enhanced effectiveness of cutting tool with such coating. ^ 1 tbl |
