Abstract

It was studied that the process of direct electroless plating on the surface of AZ31 magnesium alloy.The optimum formula of the bath is NiSO4·6H2O 25 g/L,NaH2PO2·H2O 25 g/L,citric acid 15 g/L,NH4F 10 g/L and thiourea 1 mg/L.The good electroless plated coating consisted of Ni-P was obtained in the bath with pH=9.0 at 85℃ for 1 hour.The thickness of the electroless plating is more than 10 μm.The morphology of the nickel-phosphorus coating was studied using SEM.Its phase constituent and composition were examined by XRD and EDS.The corrosion behavior of the nickel-phosphorus coating was studied by Tafel polarization in a 3.5% NaCl solution.The results showed that nickel-phosphorus coatings had a significantly better corrosion resistance than AZ31.
