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:

     •  Cost effectiveness

             - 3 to 10 times reduced duration of treatment;
             - 50% - 100 % less energy consumption;
             - 50 to100 times less working gas consumption;

     •  Distortion - none or negligiable distortions, because ion nitriding is performed at lower temperature and under vacuum;
     •  Higher surface, case and core hardness;
     •  Excellent wear resistance - the ion nitriding process produces a compound zone which is dense, nonporous, very hard, not brittle, and has a low coefficient of friction;
     •  Reproducible results and better control - the technological process of ion nitriding is fully automated and computer controlled. The parts are heated by the ion bombardment on their surface and therefore the parts are heated uniformly;
     •  Surface finish - due to minimum deformations no additional mechanical treatments are necessary;
     •  Necessity of predepassivation of stainless steel is eliminated;
     •  Masking - surfaces which require masking are easily masked with reusable mechanical masking devices or special paint for masking - 100 % effective;
     •  Excellent hygiene and working conditions - the process is not toxic and corresponds to all modern requirements for environmental control.
