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 partly volume deformations.
Plasma nitriding is a method with vast technological possibilities. 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.
By regulating the gaseous phase composition and the pulse glowing discharge parameters diffusion layer with monophase-γ'-zone (Fe4N), with monophase-ε-nitride zone (Fe2-3N) or nitrided layers without any nitride zone can be obtained.The achieved nitride zones are dense and solidly connected with the base metal.
