Abstract
Thermochemical treatment in a glow discharge in hydrogen-containing ga seous media is used to harden high-speed tool steels. Such treatment i s accompanied by saturation of the metal by hydrogen, which leads to t he appearance of hydrogen embrittlement. Transfer of hydrogen from the surface layers into the volume of the steel is accomplished by diffus ion fluxes. Accordingly, the investigation of diffusion processes occu rring under thermochemical treatment conditions in a glow discharge is of both theoretical and practical interest.
