Study on the use of furan epoxide modified graphene to enhance the corrosion resistance and wear resistance of electroless Ni-W-P coatings

In this paper, graphene oxide (GO) and furan epoxide graphene (FGO) were synthesized using graphene (G) as raw materials, and added to Ni-W-P coating as nano-reinforced materials, and various composite materials were successfully prepared by electroless plating, and the effects of G, GO and FGO as nano-reinforced materials on the surface morphology, wear resistance, corrosion resistance and microhardness of Ni-W-P coatings were studied and discussed. The experimental results show that the surface morphology of Ni-W-P-FGO coating is the most complete and dense, without obvious surface defects. In the friction test, Ni-W-P-FGO composite coating has the narrowest wear section, the wear amount is 311.617 μm2/N (minimum) and the average friction coefficient is the smallest (0.203) and it shows the best corrosion resistance in the corrosion resistance test, with the lowest corrosion current density (icorr = 0.7095 μA/cm2) and the largest corrosion resistance (Rt = 66,554 Ω·cm2).
