Nitriding & Carbonitriding
This thermochemical treatment is an enrichment of a metal surface with Carbon and Nitrogen. Like Carburizing, the phases are:
- Superficial enrichment of Carbon and Nitrogen
- Oil quench
The result is a very resistant superficial layer, even more than the result obtained with Carburizing.
Usually it is used for the treatment of steel containing aluminum and/or molybdenum to increase superficial resistance.
