摘　　要：研究了镍 磷 纳米SiO2化学复合镀层的机理,用SEM和XRD等技术分析了复合镀层的微观结构,比较了传统的化学镀镍 磷层和纳米复合镀层的沉积速度和耐蚀性.结果表明,纳米SiO2颗粒的引入加快了化学镀层的沉积速度,在同等条件下可降低化学镀的反应温度,镀层在酸、碱、盐水溶液中表现出了良好的耐蚀性能.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.
