Abstract
This paper considers an approach to improve durability of broaching tools made of high alloyed powder metallurgical high-speed steels by complex treatment which includes ion nitriding and following deposition of wear-resistant coating (Nb, Ti,Al)N using two-stage vacuum-arc discharge. Broaching tools complex hardening conditions which provide minimal wear rate when machining heat-resistant nickel alloy Inconel 718 used for turbine discs are defined.
