NitroPlas Plasma Nitriding
The NitroPlas white layer is hard and tough reducing the need for post-treatment grinding. The nitride precipitates produced in the diffusion zone are smaller and more evenly dispersed than those produced by gas nitriding which considerably improves the toughness and fatigue properties when using NitroPlas.
Problems associated with conventional plasma nitriding, where the plasma is generated on the parts, such as overheating by the hollow cathode effect and damage caused by arcing are thus greatly reduced.
