Conclusions
-
1.
Mathematical models of the dependence of the thickness of the diffusion layer on carbon concentration and saturation temperature during the diffusion chromium plating of carbon steels are obtained.
-
2.
The growth rate of the diffusion layer during the chromium plating of steels in a moving mixture is appreciably higher (by a factor of 2.5–4) than that during standard saturation in a stationary charge.
-
3.
The activation energy of the chromium-plating process in a moving mixture is approximately 40% lower than that in the stationary mixture. Its value depends to a lesser degree on the saturation parameters (temperature and time) in the first case than in the second; this suggests a higher stability of the results of diffusion metallizing in a moving mixture.
