铝基化学镀镍浸镍前处理的研究进展
Development of Nickel Immersion Pretreatment of Electroless Nickel Plating on Al Alloy Surface
摘要
Abstract
The key line to obtain electroless nickel plating with excellent adhesion to the substrate is the pretreatment process. The zincate treatment method as a pretreatment process has been studied by many researchers, and its effect is good. However, its disadvantages cannot be ignored. The nickel immersion method can avoid these shortages, and it is expected to replace zinc immer-sion method. The present article introduced the research status and the principle of zincate treatment. At the same time, this paper divided the relative zincate treatment into activation-nickel immersion method, alkaline elctroless nickel pre-plating method, and double nickel immersion method. The solution of activation-nickel immersion method normally does not 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. The solution of alkaline nickel pre-plating is a kind of nickel salt solution with certain re-ducing agent which pre-plates a thin layer of nickel on the surface of aluminium base. The principle of this method is the same as electroless nickel plating. This paper analyzed the difference and the relationship of the two kinds of nickel immersion methods and the combined treatment. Finally, this paper pointed out the development direction of nickel immersion pretreatment process for alu-minum alloy as follows. First, in order to simplify the process, the single nickel immersion method is expected to replace the doub-le nickel immersion method. Second, the non-poisonous, low-contaminative and fluoride-free solution of nickel immersion is expec-ted to be developed. Third, the formulation of nickel immersion solution should be optimized to make the bonding strength better.关键词
