介绍了一种新的锌镍合金的镀液配方及工艺,在镍含量只有锌含量的一半镀液中得到含镍量为13%的镀层,且镀层具有防腐蚀性能好、美观的优点,镀液稳定、深度能力好、分散能力好、在很大的电流密度和浓度范围内镀层比较均匀、工艺容易操作和成本较低,可用于生产。并通过理论研究和实际摸索确定了合金中含镍量的一种测定方法——分光光度法,采用丁二酮肟络合镍的方法,能准确的测定镀层中含镍量。
A new zinc-nickel alloy plating bath formulation and process is introduced. The nickel-containing plating solution has a nickel content of 13%, and the plating layer has the advantages of good anti-corrosion performance and beautiful appearance. The plating Liquid stability, good depth ability, good dispersing ability, coating is very uniform in a large current density and concentration range, the process is easy to operate and the cost is lower, which can be used in the production. And through theoretical research and practical exploration to determine the nickel content of a determination of the method - spectrophotometry, dimethylglyoxime complex nickel method, can accurately determine the nickel content of the coating.
