The gas nitro-carburizing technique of Fe-based powder metallurgy with chromium was studied. The microstructure and phase-structure of nitride layer were analyzed. The results show that: Fe-based powder metallurgy with chromium has high reaction rate and diffusion velocity in gas nitro-carburizing. Its nitride layer is made of compound layer and diffusion layer. The compound layer mainly consists of α phase and γ' phase.
