摘要The effect of graphene/graphene oxide (G/GO) on the wear resistance and thermal conductivity of Co-Ni alloy coating has been studied. The results of x-ray diffraction analysis showed that the coatings exhibited face-centered cubic and hexagonal close-packed structures, and the coating grains were all oriented in (111) direction. Addition of G/GO caused the lattice of the coatings to become distorted and promoted coating crystallization. Raman spectrometry analysis revealed that the graphene was most complete and orderly in the Co-Ni-G composite coating. The thermal conductivity of the Co-Ni alloy, Co-Ni-GO composite coating, and Co-Ni-G composite coating was determined by laser heat conduction analysis to be 421.112 W/(m K), 305.942 W/(m K), and 341.829 W/(m K), respectively. The friction coefficient of the Co-Ni-G composite coating was the lowest at 0.37. The composite coating mainly exhibited sliding friction and showed the best wear resistance, whereas the alloy coating mainly exhibited adhesive friction.
