| 中文摘要: |
| 铝基表面化学镀镍层以其优良的耐磨、耐蚀、钎焊性等被广泛应用各个领域,尤其在近几十年发展十分迅速。但由于铝及其合金表面较高的化学活性,在其表面直接化学镀镍很难获得结合力好的镀层。众多研究表明,要获得结合力好的镀层关键在于前处理工艺的选择。浸锌法是目前研究较多,效果较好的前处理方法。本文简述了浸锌法的原理、研究现状及目前存在的问题。同时指出浸镍法可以避免这些不足,且有望取代浸锌法。较详细地阐述了浸镍法的原理、研究现状。同时,将文献中使用到的浸镍法分为活化浸镍、碱性预镀镍和二次浸镍法,活化浸镍液中一般不含还原剂,主要通过置换反应生成一薄层具有催化作用的镍,属于置换镀镍,进而促使化学镀过程中镍的紧密均匀地沉积；碱性预镀镍则是通过带有还原剂的镍盐溶液,在铝基表面预化学镀上一薄层镍,其原理与化学镀镍相同,对比分析了两种浸镍法及其组合处理法之间的区别与联系。最后,展望了浸镍法未来的发展方向。 |

| The elctroless nickel plating layers on aluminum alloy were widely used in various fields because of its excellent wear resistance, corrosion resistance, brazing, etc. Especially in recent decades, it developed in a rapid speed. Aluminum alloy is difficult to be plated because of high chemical activity. Many researches shows that In order to obtain electroless nickel plating with excellent adhesion to the substrate, the key lines is the pretreatment process. Zincate treatment method as a pretreatment process was studied by many researchers, and its effect is good. However, its disadvantages never be ignored. The nickel immersion method can avoid these shortages, and it is expected to replace zinc immersion method. The present article introduces the research status of zincate treatment. At the same time, this paper reviews the mechanism and research situation of activation-nickel immersion method, alkaline elctroless nickel preplating method, double nickel immersion method. The solution of activation-nickel immersion method always don’t contain reducing agent. This method produces a thin layer of nickel catalyst by substitution reaction, ?prompting the deposition of electroless nickel plating closely and evenly in the later process. It belongs to the displacement nickel plating. The solution of alkaline nickel preplating is a kind of nickel salt solution with s reducing agent. This method’s principle is the same as electroless nickel plating. This paper analyzes the difference and contact of the two kinds of nickel immersion methods and the combination treatment?. Finally, the development direction of nickel immersion pretreatment process for aluminum alloy is forecasted |
