In vacuum heat treatment of titanium alloys the processes of gas impregnation, oxidation, and sublimation are responsible for the formation of the physicomechanical properties of the surface layers of the alloy. In this work a study was made of the process of gas impregnation of VT1-0, VT5, VT5-1, and PT-7M titanium alloys at pressures of 13.3, 1.33, and 0.133 mPa with a temperature of 1123 K and a hold of 8 hours. The principles of evaluation of the depth of the impregnated layer were formulated.
