摘要：
The paper describes the influence of hydrogen content in a working gas on diffusion processes at ion nitriding of martensitic and austenitic steels. It is found that the presence of hydrogen in a working space of a vacuum chamber contributes to the increase in nitrogen diffusion depthward the material. Dependence of the hardened layer thickness and depth distribution of microhardness on gaseous composition was obtained. The structure of steel nitrated layer with various content of hydrogen in a vacuum chamber was studied.
