1.1 Cementation
The carburizing treatment applied to steels is a thermochemical surface treatment for carbon enrichment carried out in the austenitic phase, generally 900 to 980°C. Higher temperatures can be envisaged for low-pressure carburizing (subject to metallurgical compatibility).

After cooling by quenching, it is designed to achieve surface hardening, creating a hardness gradient from the surface to the core.
We know that the surface hardening of an iron-carbon alloy by martensitic transformation is directly related to its carbon content (figure 1...
