FIELD: metal working, namely processes for applying wear resistant coatings onto cutting tools.
SUBSTANCE: method is realized at plasma-vacuum deposition of multi-layer coating. Method comprises steps of depositing lower layer of titanium and aluminum-alloyed metal; intermediate layer of titanium nitride or carbonitride and metal; upper layer of intermediate layer material alloyed with aluminum; using silicon, iron chrome, molybdenum or zirconium as metal. Layers of coating are deposited 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: enhanced efficiency of cutting tool, improved adhesion and cohesion strength of layers and base material.
