FIELD: metallurgy.
SUBSTANCE: method of nitridation of products from titanic alloys in a glow discharge involves carrying out of the noted nitriding in a nitrogen-argon gas mixture, using the noted nitrogen-argon gas mixture with a percentage ratio of 60% N2 to 40% Ar, and the noted nitriding in a glow discharge is carried out in magnetic field at a temperature of 650-750°C for 4 hours, voltage in the discharge gap of 450-550 V and pressure in a vacuum chamber of 10-1-1 Pa.
EFFECT: process of surface saturation with nitrogen ions during ion nitriding of titanic alloys is intensified, and a developed diffusion zone on a titanium base of the order of 50-70 mcm is obtained.
