Conclusions
-
1.
The difference in the properties of chromized carbon steels between the outer carbide layer, sublayer, and base metal can be reduced by means of a diffusion treatment.
-
2.
The quenching temperature and holding time at this temperature must be selected to ensure formation of a sublayer enriched in chromium with a high hardness. This is achieved by the diffusion of chromium from the carbide layer.
-
3.
Hardening under the optimal conditions substantially increases the resistance to impact loading.
