摘　　要：文章主要研究了Ni-SiC纳米复合电镀工艺条件对镀液均镀能力的影响。研究表明:要获得好的分散能力和均镀能力,镀液的搅拌强度既不能太大,也不能太小,应保持适中;镀液中纳米SiC微粒浓度和镀液pH对均镀能力影响不显著,但pH不能过高;温度则应控制在40～50℃。此外,整平能力试验表明在镀液中加入纳米微粒,出现负整平作用。电化学极化曲线表明镀液中存在少量纳米微粒,可增大阴极极化,有利于得到结晶细致、光亮平整的镀层。In the paper,the effect of Ni-SiC Nano-composite coating on dispersant capability of electrolyte was studied.It was showed that,to obtain good throwing power and dispersant capability of electrolyte,stir intensity should keep moderate.The content of SiC and pH had little effect on dispersant capability.But the temperature must be controlled between 40 ℃ and 50 ℃.In addition,good leveling power and good smooth coating could be gotten by adding some SiC particles into the solution.
