Abstract:This paper studies the mechanism of electrolytic Ni-P-Nano SiO_2 composite coating. The microstructure of the composite plating was analyzed by the scanning electron microscopy (SEM) and X-ray diffraction (XRD) technology. The traditional electrolytic Ni-P plating and the new composite coating have been compared in the deposition rate and corrosion resistance. The results indicated that the appended nano SiO_2 could increase the deposition rate, improve the microstructure and reduce the reaction temperature of electrolytic layers. The coating also has a good corrosion resistance in HCl, NaOH and NaCl solutions.
Keywords:electroless plating  Ni-P coating  nano SiO_2  composite coating  corrosion resistance
