Abstract

An economical method for applying nitride layers to titanium and titanium alloys. In a short time, layer thicknesses of 20 mu m are achieved by nitriding under pressure in an ammonia atmosphere. Temperatures of 500 to 1000 DEG C and pressures of 0.2 to 10 Mpa are required for this purpose.
