Abstract-Graphene sheets and copper powder were dispersed into Polyvinyl Alcohol (PVA) solution by magnetic stirring, and then pre-coating the mixed solution on the polished AISI4140 substrate. Then laser cladding and laser remelting process were used to fabricated graphene copper and iron composite coating. Microstructures and composition of the composite coating was studied by using Scanning Electron Microscopy (SEM), Energy Dispersive Spectrometer (EDS) and Raman spectroscopy. Raman spectrum, SEM results proved that graphene sheets were dispersed in the composite coating. Vickers hardness test results showed that the composite coating had higher hardness values. With the graphene addition, the tribological performance of the composite coatings became better, and for pure copper iron coating, the average friction coefficient was 0.16, while for the 10% graphene copper iron coating, it was reduced to 0.13.
