Microstructure and wear behaviors of laser clad NiCr/Cr3C2-WS2 high temperature self-lubricating wear-resistant composite coating
چکیده انگلیسی
► WS2 is utilized to produce high temperature self-lubricant wear-resistant composite coating by laser cladding. ► Noticeably, the coating added withWS2 has a higher microhardness because of the formation of the hard phase (Cr,W)C. ► The average friction coefficients both decrease with the rising of temperature, but the wear rates both increase. ► The coating added with WS2 has a lower friction coefficient whatever at ambient, 300 °C, 600 °C, and a lower wear rate only at 300 °C.
