Abstract The Ni/n-SiO2 coating was deposited by pulse-reverse brush plating.The surface morphology of the coating was analyzed by SEM,the porosity of the coating was evaluated and the corrosion resistance of the coating was measured in the solution of sea water.The corrosion mechanism of the coating was also discussed.The result shows that,compared with Ni and Ni/n-SiO2 coatings deposited by direct current,the Ni/n-SiO2 coating by pulse-reverse current has much compact and finer surface morphology,lower porosity and better corrosion resistance.

Key words: direct current(DC) pulse-reverse current(RC) electro-brush-plating nano composite coating
