초록
WC-10Co-4Cr have been well known material with attractive corrosion resistance and excellent hardness in the WC-basedcoatings. To widen the application of the WC-10Co-4Cr coatings deposited on high-hardness metal cutting tools, theinvestigation of its preparation parameters and properties are required. In this study, dense micro-structured WC-10Co-4Crcoatings deposited on high-hardness M42 steel were performed with high velocity oxy-fuel (HVOF) spray process. Theprepared coatings exhibit excellent properties by improving the size of spray gun and injecting high flow nitrogen into theflame stream. A maximum micro-hardness of 1353.3 HV0.3 was achieved. In addition, the frictional properties of uncoated M42steel and the WC-10Co-4Cr coating were comparably studied under dry sliding wear tests. A low friction coefficient of 0.34-0.37 was achieved for WC-10Co-4Cr coating, showing a 57% decrease than that of uncoated M42 steel. X-ray diffractometrywas used to identify the phase composition, and scanning electron microscopy was adopted to characterize the microstructureof deposited coatings and worn-out surfaces.
