ABSTRACT:
Embodiments of the present invention may provide a coating material having heat resistance, abrasion resistance and low friction characteristics, which is coated on an operating component such as a rotating shaft working at a high speed without oil supply in a medium temperature environment (400° C.˜500° C.). This is so that the operating body can sufficiently withstand friction, heat generation and abrasion caused by contact with a bearing. The coating material of the present invention comprises 15 to 25 wt % antimony trioxide (Sb2O3), 50 to 70 wt % binder, 10 to 20 wt % tungsten disulphide (WS2) and 5 to 15 wt % silver (Ag). The binder comprises 60 to 80 wt % nickel (Ni) and 20 to 40 wt % chromium (Cr).
