Nitriding is a thermochemical treatment used on steels, whose function is to modify the properties on the surface of the components, by virtue of the diffusion of nitrogen and the generation of a layer of nitrides. 

 

It is used to increase wear, corrosion and fatigue resistance. In many cases the Nitriding  process is an alternative to other surface treatments such as hard chrome and cementing, obtaining a similar or superior quality.

 

As a result of the nitriding process

the steel acquires:

 

High hardness of the surface layer

High wear resistance

High fatigue resistance

High resistance to cavitation 

High corrosion resistance 

No deformation and modification in geometry

Low tendency to scratch
