Nitriding & Carbonitriding

Superficial enrichment of metal with Carbon and Nitrogen to increase resistance

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
  • Tempering

The result is a very resistant superficial layer, even more than the result obtained with Carburizing.

Common usages

Usually it is used for the treatment of steel containing aluminum and/or molybdenum to increase superficial resistance.
