The paper considers the study of vacuum cementation of steels 20, 20X and 20X2H4A. The influence of parameters such as temperature and time of vacuum cementation on the nature of carbon distribution in the diffusion layer and on the effective thickness of the steel layer is analyzed. Experimentally established dependences show an increase in the thickness of the diffusion layer according to the parabolic kinetics of layer growth and the achievement of a constant value of the carbon concentration, which can be used as the basis for solving problems of modeling mass transfer in the future.
