Plasma Nitriding – Technical Information
Plasma (Ion) Nitriding
Plasma nitriding is a surface hardening process which is apllied ferrous materials.
Plasma Nitriding process which is performed in special designed vacuum furnaces, is achieved by directing the ionized process gases by electric current to the workpieces.
When the workpieces are reached to diffusion temperature by slow heating up, by means of the plasma phase surrounding the workpieces uniformly, nitrogen atoms start to diffuse into from the surface
The plasma nitriding process temperature can be between 350-580 ° C, depending on the type of material, the heat treatments previously applied, and the desired surface properties. The process time can range from 15 minutes to 120 hours depending on the desired characteristics.
