| Abstract: | Using vacuum fusing sintering method, a series of Co base alloy-tungsten carbide composite coatings with different tungsten carbide contents have been obtained on the surface of steel. Observed and analysed by metallographic microscope and scanning electron microscope, the microstructure of composite coatings consists of Co base solid solution and hard particles distributed in the matrix. The phase structure of composite coatings was further determined with X-ray diffractometer. The eutectic microstructure of coatings was identified by using EDXA spectra analysis. On the basis.of comprehensive analysis, the model of vacuum fusing process is suggested. |
