СПОСОБ ПОЛУЧЕНИЯ МНОГОСЛОЙНОГО ПОКРЫТИЯ ДЛЯ РЕЖУЩЕГО ИНСТРУМЕНТА

摘要

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