Hardening of a quick-speed steel tool through nitration process with nitrogen controlled potential

The study of the gas nitriding method, which allows obtaining high-quality diffuse layers in high-speed steel P6M5 on basis an internal nitrogen hardening zone with no brittle nitride zone, has been viewed. Research results phase composition nitrided a change potential atmosphere during dilution ammonia are presented. Nitrided tool increased resistance drilling constructional and titanium alloy, is due to precipitation treatment nitrogenization using tungsten nitrides, given.
