Nitriding of steel --(strengthen nitriding; Corrosion resistant nitriding)

A chemical heat treatment process in which nitrogen atoms infiltrate the surface of steel to form a nitrogen-rich hardening layer. Compared with carburizing, nitriding parts have: high hardness and wear resistance, high fatigue strength, higher anti-bite, higher corrosion resistance, nitriding process in the steel phase change temperature below (450-600℃), thus small deformation, volume slightly swell. Disadvantages are long cycle (general gas nitriding soil nitriding time as long as tens to 100h), high cost, thin permeability layer (generally about 0.5mm) and brittle, can not bear too much contact stress and impact load.
