    Abstract:

    Ni-Fe-Co-P-CeO2 composite coating was prepared by spray electrodeposition technique. The surface morphology, Cross section morphology, microstructure and composition of the composite coating were tested by SEM, XRD, EDS, etc. At the same time, the hardness, wear resistance and corrosion resistance of the composite coating were characterized. The performance of the nano-rare particles CeO2 on the coating performance was investigated and analyzed. Impact. The results show that the multi-component composite coating is amorphous. With the increase of CeO2 particle concentration in the plating solution, the microhardness, wear resistance and corrosion resistance of the composite coating are firstly enhanced and then weakened. When the CeO2 particle concentration is 1g/L, the surface of the composite coating is uniform and dense, and its microhardness reaches the maximum value (598.21HV), and has the best wear resistance and corrosion resistance.
