... Ion nitriding is a vacuum process that takes place in the plasma of high current glow in a vessel. The workpiece, in this case, a gear, forms the cathode, whereas the vessel wall is the anode. The vessel is evacuated prior to nitriding. Gas containing nitrogen is then introduced, and the treatment...
