Plasma nitriding

We also offer plasma nitriding through our technology network.

Plasma nitriding is one of the most environmentally friendly surface hardening processes, as no toxic gases are used. 

A mixture of hydrogen and nitrogen-containing gas flows at low pressure into the furnace room and is ionized by applying a voltage (glow discharge). An ionized gas is referred to as plasma. The ions generated by the glow discharge are accelerated onto the surface of the workpiece, deposit the dissolved nitrogen in the surface, and form metal nitrides, which increase the hardness in the surface layer. 

Relatively low treatment temperatures ensure low distortions. 

The ability to minimize the formation of the bond layer makes plasma-nitrided surfaces with a slight finish an ideal PVD coated surface.
