Abstract

Graphene sheets and nickel powder were dispersed into Polyvinyl Alcohol (PVA) solution by magnetic stirring, and then pre-coating the mixed solution on the polished AISI4140 substrate. And after laser sintering, graphene nickel composite coating was successfully fabricated. Microstructures and composition of the composite coating before and after wear and friction experiments was studied by using Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM), Energy Dispersive Spectrometer (EDS) and Raman spectroscopy. Raman spectrum, SEM and TEM results proved that graphene sheets were dispersed in the composite coating. Nano indentation test results showed that graphene nickel composite coating had been greatly strengthened, and for pure nickel coating, the average friction coefficient was 0.35, while for the 10% graphene nickel coating, it was reduced to 0.13.
