The surface of 316 stainless steel was modified by solid carburizing method. The phase composition,microstructure,microhardness and relative wear resistance of the composite were analyzed by XRD, SEM, microhardness tester and ML-100 wear test machine. The results show that the carbide particles appear on 316 stainless steel surface at 1120 ℃ for 10 h and 850℃ for 1 h by solid carburizing method. The in-situ reaction layer surface can be divided into three layers, such as the no-grain boundary layer, the gra...
