摘要：

Fe-TiC surface composite was prepared in situ on a surface of cast steel by means of cast-sintering technique. The microstructure of this material was investigated by means of SEM, electron probe and XRD. Results show that the TiC and (Fe,Cr)(7)C-3 carbides in an iron matrix were achieved on the surface of cast steel during cast-sintering. From the top surface of sample to that of the master-steel, the concentration of Ti, Cr and Ni as well as the quantity of both TiC and (Fe,Cr)(7)C-3 carbides decreased gradually, and the morphology of (Fe,Cr)(7)C-3 transforms from strip-chunky into make-and-break reticulation. There was an excellent metallurgy-bond between the surface composite layer and the mastersteel. (c) 2006 Elsevier B.V. All lights reserved.
