Nitrocarburizing ferrous PM materials at low temperatures

Wear resistant hard surfaces and shock resistant cores enhance the life of mechanical components such as gears, shafts and cams. Low carbon steels can provide the core properties that such parts need while the surface characteristics can be created by the process of nitriding and nitrocarburizing. M. Rosso, G. Scavino and G. Ubertalli of the Department of Materials Science and Chemical Engineering, Polytechnic of Turin, Italy, use experimental results from research into nitrocarburizing to show the effect it has on sintered materials.
