Plasma nitriding - the most advanced case-hardening technology today
Nitriding in pulse glowing discharge (PLASMA nitriding) is an efficient method to increase hardness and wear-resistance of metals and alloys. Basic technological advantage of the method is the low temperature at which the process takes place resulting in negligible volume deformations.
Plasma nitriding is a method with vast technological possibilities, suitable for treating parts with very complex shapes and geometries.
Diffusion layers of desired structure can be obtained, i.e. the diffusion saturation process is controllable and can be optimized to comply with the particular requirements to the layer qualities. The achieved nitride zones are dense and solidly connected with the base metal.
Plasma Nitriding is also capable of treating parts of Stainless Steel without the necessity of a predepasivation process. The treatment could also be carried out so that it could preserve the corrosion resistance of the steel.

The process of Ion Nitriding
Typical feature of plasma nitriding is the active participation of the treated parts in the glow discharge - the parts act as a cathode, while the chamber acts as an anode. There are many advantages of this method over conventional gas nitriding.
Many parts and tools of all industries are subject to plasma nitriding and nitrocarburising. Different examples demonstrate how plasma nitriding and nitrocarburising solve tough tasks.
