摘要: 采用脉冲换向电刷镀方法制备了Ni/n-SiO2复合镀层，应用SEM对镀层表面形貌进行了分析，测试了镀层的孔隙率，以及镀层在海水浸泡条件下的耐腐蚀性能，讨论了镀层的耐腐蚀机理.实验结果表明：与直流工艺条件下的电刷镀镀层相比，脉冲换向电刷镀工艺得到的Ni/n-SiO2复合镀层具有致密精细的表面、较小的孔隙率和较高的耐腐蚀性能.

关键词 ：直流, 脉冲换向, 电刷镀, 纳米复合镀层

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
