| Abstract: | The Co base self fluxing alloy coating was obtained on the 40Cr steel by using vacuum fusing sintering process. The microstructure of the coating is analysed with metallographic microscope and X ray diffractometer. The wear tests with ring on block wear test machine and corrosion tests were carried out. The wear resistance and the corrosion resistance of vacuum fusing Co base alloy coating, rapid cooled cast iron and GCr15 steel were compared. The results show that the wear resistance and the corrosion resistance of the vacuum fusing Co base alloy coating are higher than those of rapid cooled cast iron and GCr15 steel. |
