Basic Theory of Ion Nitriding

Plasma or 'ion nitriding' is a method of surface hardening using glow discharge technology to introduce elemental nitrogen to the surface of parts for subsequent diffusion. In a vacuum, high voltage is used to form plasma, and molecular nitrogen atoms are disassociated into an atomic form and are accelerated to impinge on the part. This ion bombardment heats the workpiece, cleans the surface and hardens the metal.
