СПОСОБ ПОЛУЧЕНИЯ МНОГОСЛОЙНОГО ПОКРЫТИЯ ДЛЯ РЕЖУЩЕГО ИНСТРУМЕНТА

摘要

FIELD: application of wear-resistant coats on cutting tools; metalworking. ^ SUBSTANCE: proposed method includes vacuum plasma application of multi-layer coat: lower coat contains titanium and metal compound; intermediate layer contains titanium nitride or carbonitride and metal and upper layer contains material of intermediate layer alloyed by molybdenum; used as metal is aluminum, iron, chromium, zirconium or silicon; application of layers is performed by means of three cathodes located horizontally in one plane; two cathodes are located opposite each other and are made from titanium and metal; third cathode which is sectional in form is made from titanium and molybdenum. ^ EFFECT: increased serviceability of cutting tools; enhanced strength of adhesion of layers with base. ^ 1 tbl
