Abstract: (262 Views)
Well-known corrosion and wear resistance of electroless nickel phosphorus (NiP) coatings led studies on upgrading of mechanical and chemical properties and feasibility of its application in different industries. In this study, the effect of coating applying time on corrosion and wear resistance of the electroless nickel phosphorus-nano graphene oxide composite coating (NiP/GO) on st37 steel substrate was studied, comparing the simple electroless nickel phosphorus coatings. According to the polarization and electrochemical impedance spectroscopy results, NiP/GO deposit possessed more corrosion resistance than NiP coatings and the appropriate coating time was 60 minutes. The results also revealed that the presence of graphene oxide in nickel phosphorus coatings and increasing of coating applying time causes increasing of the coating microhardness by 279.8 HV and the friction coefficient by 19.33%.
