The surface of irons and steels can be hardened by introducing nitrogen (nitriding), nitrogen and carbon (nitrocarburizing), or nitrogen and sulfur (sulfonitriding) into the surface. Nitriding typically aims for a high-hardness case created by the diffusion of nitrogen into the alloy lattice and by forming a diffusion zone with nitride precipitates. This area of high hardness results from lattice distortion caused by alloy nitrides. Nitrocarburizing, on the other hand, is aimed at forming an iron-carbonitride compound layer on the very surface of a treated part to obtain higher corrosion and wear resistance.
