Microstructure and wear properties of Fe-VC-Cr{sub 7}C{sub 3} composite coating on surface of cast steel
- School of Manufacturing Science and Engineering, Sichuan University, Sichuan Chengdu 610065 (China)
An Fe-VC-Cr{sub 7}C{sub 3} composite coating on the surface of cast steel was produced by a novel metal-coated casting technique. The microstructure and wear properties of the product were studied by means of X-ray diffraction, electron beam probe, scanning electron microscopy, and wear testing. The results show that the composite coating consisted of VC and Cr{sub 7}C{sub 3} as the reinforcing phases and {alpha}-Fe as the matrix. The composite coating was metallurgically bonded to the cast steel substrate. The quantity of VC and Cr{sub 7}C{sub 3} carbides decreased gradually from the top surface of the composite coating to the cast steel substrate. The Fe-VC-Cr{sub 7}C{sub 3} composite coating displayed excellent wear-resistance under dry sliding wear test conditions.
