Definition - What does Nitrocarburizing mean?
Nitrocarburizing is a thermally induced chemical process involving the diffusion of carbon, oxygen and nitrogen into a metal's surface to improve surface hardness and wear resistance.
Corrosionpedia explains Nitrocarburizing
Nitrocarburizing is industrially performed in a gas nitriding furnace at temperatures up to 1202°F (650°C). In this furnace, nitrogen impregnation and gaseous infusion is performed on the metallic surface being treated. The key benefits of nitrocarburizing include improved resistance to wear and corrosion, and better fatigue strength.
Nitrocarburizing is performed at sub-critical temperatures on the surface of carbon steel to generate a harder case and soft core with a very thin compound layer on the surface. The compound layer is wear and corrosion resistant while the thin case layer enhances the fatigue resistance of the component.
