Abstract

Plasma nitrocarburizing of 17-4PH martensitic stainless steel was conducted at 430°C with or without rare earth (RE) addition. The growth kinetics, microstructure, hardness and wear resistance of the modified layer were studied by using the OM, XRD, microhardness and pin-on-disc tribometer. The results show that the RE nitrocarburized layer is more compact than that formed by nitrocarburizing without RE addition. The RE does not change the surface phase composition and the nitrocarburized layer consists mainly of nitrogen and carbon expanded martensite (α'_N), γ'-Fe₄N and CrN phases. By adding RE, the layer depth and surface microhardness of the layer can be increased by 46% and 100 HV0.1, respectively. At the same time, the wear resistance of the surface layer of the RE nitrocaburized steel can also be improved obviously.
