英文摘要	The NiCrWRe sprayed coating was prepared on the surface of 45 carbon steel by using flame spraying. The sprayed coating was characterized by abrasive wear resistance test, and compared with the NiCrW alloy coating. Scanning electron microscope, energy dispersion spectroscope and X-ray diffraction were employed to analyze the morphologies of the coatings, as well as their phase structures. The bonding strength of coating/substrate interface was tested by means of tensile strength. The results showed that the coating is firmly adhered to substrate, and contains the hard phase with higher proportion. Adding rare earth element can obviously increase the wear resistance of the coatings. In the given conditions, the wear resistance of NiCrWRe coating is much higher than that of NiCrW alloy coating.
