| Abstract: | This paper deals with the composite treatment of hollow cathode plasma sintering and Cr-Mo plasma surface alloying on FN0205.Alloying layer can be formed on the surface when the sintering was implemented.The layer thickness reaches 68 μm and Cr,Mo contents reach to 10%,5% at surface layer.The phases of alloying layer consist of Fe,Fe-Cr,Cr7C3,Cr23C6,Mo2C.The micro-hardness of alloying layer reaches 710HV and a gradient distribution of micro-hardness is observed in the layer. |
