摘要
化学镀镍在实际生产中普遍存在镀液稳定性差、使用寿命短、镀速慢和pH值范围窄等问题。为此,采用对比试验和正交试验方法,以镀速、孔隙率、镀液稳定性和镀层硬度为评价指标,深入研究了复合配位剂对镀液和镀层各种性能的影响及稳定剂在镀液中的作用,在此基础上得到了最优复合配位剂的配比,从而很好地解决了镀液稳定性差、使用寿命短、镀速慢、pH值范围窄等常见问题。
With a view to the poor stability, short service life, low deposition rate, and narrow range of pH value of the plating bath for electroless Ni -P plating, the effects of the complexing agents and stabilizing agents on the performances of the plating bath and coatings were investigated using comparative tests and orthogonal tests, and the action of the stabilizing agents was discussed as well. Thus the plating rate, the porosity of the electroless Ni -P coating, the stability of the plating bath, and the hardness of the coating were studied in details, and the optimized composition ratio of the combinatory complexing a-gents was established. It was anticipated that the present research would help to resolve the above-mentioned bottlenecks for electroless Ni-P plating.
