Short answer: Plasma (ion) nitriding hardens a steel surface in a low-pressure glow discharge: ionized nitrogen bombards the part, diffuses in and forms a hard, low-friction nitride case without the white-layer and distortion of salt or gas nitriding. Running below the tempering temperature of the core, it needs no quenching, so precision parts keep their size while gaining wear and fatigue resistance — widely used on dies, screws, valves and transmission components.
