| 摘 要： | 在前期确定的基础化学镀镍液配方基础上,分别添加KI、苯骈三氮唑、含硫有机杂环化合物A等稳定剂,考察了其对镀液的稳定性能、镀速、镀层性能等影响.优选了一种不仅能使镀液稳定性能良好,而且镀层耐蚀性能优异的药品A作为化学镀镍液的稳定剂.研究表明,合适的稳定剂在不改变镀层中磷含量的基础上,不但可以提高镀液的稳定性,同时还可获得高耐蚀性镀层.

| Abstract: | To the basic electroless nickel bath compositions confirmed in our previous work,three electroless nickel bath stabilizers of KI,benzotriazole and organic heterocyclic compounds A containing sulfur are added respectively,and the stabilizing effects of these three stabilizers on electroless nickel bath are inevstigated.A is chosen as an excellent electroless nickel bath stabilizer,which can not only stabilize the bath very well but also bring an excellent corrosinon resistance to the coatings.The research results show that an appropriate stabilizer can improve both the stability of the bath and the corrosion resistance of the deposit without changing the P content in the deposit. |
