FIELD: metallurgy.
SUBSTANCE: method of ion nitration of titanium alloys in nitrogen-argon gas mix at 60 % N2-40 % Ar ratio involves ion nitration in magnetic field at 650-750 °C in vacuum chamber and 500-600 V voltage in the air gap, first at low gas mix pressure of 10-1-1 Pa for 4 hours, then at the gas mix pressure of 100-300 Pa for 1 hour. It allows for obtaining of developed diffusion zone with increased micro-hardness and nitrated layer depth in a titanium base.
EFFECT: improved operation characteristics of products.
