摘　　要：在中温化学镀镍-磷合金体系下,采用酸性镀液配方进行周期循环实验,研究了添加方式对镀液的沉积速度、使用寿命以及镀层性能的影响。实验结果表明,添加工艺对镀液寿命及镀层性能有较大的影响,当添加比例为开缸液的15%时,镀速在第1周期可达到20.40μm/h,在第10周期仍有12.10μm/h,镀液使用寿命大于10个周期,所得镀层性能较好。The influence of supplement methods on the service life, the stability and plating rate of solution, and the performances of Ni-P alloy was researched via MTO experiment using acidic bath under medium temperature. The result shows that supplement methods have much effect on the service life of solution and the performances of Ni-P alloy. With the proportion of 15% to replenish fresh solution, the service life of solution is more than 10 MTO, with deposition rate (20.40) μm/h and 12.10 μm/h at the first MTO and the last MTO, respectively, and good electroless coating is obtained.
