外文摘要：Graphene oxide (Go) has excellent mechanical properties, corrosion resistance, solid lubricant properties, and no biotoxicity. In this study, CoCrFeNiMn coating adding 2 wt% single layer of Go was prepared by laser cladding (LC) on the surface of Q235B. To explore the possibilities of Go as a reinforced powder. It was found that the alcohol stirring method could uniformly mix Go with HEA powder and would not destroy its microstructure. The main phase composition of the coatings does not change, but peaks of oxides and carbides were generated in the coatings. The carbide and oxide generation in the coating was demonstrated by EDS spot scanning. The addition of Go increased the microhardness of the coating by 51.33 %. The average coefficient of friction (COF) of the HEA/Go coating decreased by 16 %, the wear rate decreased by 82.05 %, and the wear weight loss decreased by 77.26%. Improvement of the wear properties is mainly attributed to the generation of oxide film during friction.
