ABSTRACT:
There is provided a coating material having heat and abrasion resistance and low friction characteristics, as well as a method of utilizing the same. The coating material comprises 20 to 40 wt % Cr2O3, 40 to 60 wt % binder, 10 to 20 wt % WS2, and 10 to 20 wt % Ag. The binder comprises 60 to 80 wt % Ni and 20 to 40 wt % Cr. The binder may further comprise above 0 to 10 wt % Al. The coating method comprises the steps of pulverizing the coating material, pulverizing a binder, applying the pulverized binder to a surface of a workpiece to form a first layer, applying the pulverized coating material to the first layer to form a second layer, and grinding and polishing the surface of the second layer.
