Liquid cementation

The conventional thermal treatment for hardening does not alter the chemical composition of steel, ie, the material starts treatment with 0.4% carbon and it ends with 0.4% carbon. However, sometimes it is necessary to bring the steel to complete modifications on their chemical composition to improve the properties of its surface. These changes are obtained through thermo-chemical treatment. This treatment aims primarily to increase the hardness and strength of the material wear of the surface and at the same time maintaining the core ductile (soft) and tenacious.
