Abstract

Add CeO2 in medium phosphorus content Ni-P composite coating has been attracted attention in recent years. So, we add different amounts and different size of CeO2 in the nickel plating solution, then the morphology and crystal structure of the coating are characterize by scanning electron microscope (SEM) and X-ray diffraction analysis (XRD) respectively. As a result, the content of CeO2 in the coating increases with the rise of the CeO2 concentration, moreover the grain of the Ni coating turns to amorphous state and the grain got refined. Finally, the corrosion resistance of the coating was tested with the method of Electrochemical impedance (EIS) and linear polarization. Both methods get same result. The corrosion resistance of the coating enhances greatly after added CeO2 in the plating solution. Different diameter of CeO2 got different corrosion resistance, however mirco-CeO2 got better performance which may due to micro-CeO2 could refine the grain of the coating more efficient.
