摘　　要：采用碱性预镀+酸性化学镀镍的方法在锌合金表面镀镍,研究了pH值、温度和主要镀液成分对锌合金表面化学镀镍速率的影响,结果表明:在镀液不发生分解时,镀速随pH值和温度的提高而迅速上升;硫酸镍、次亚磷酸钠和主络合剂在镀液中的含量存在极限值,超过此值镀速开始下降。优化工艺条件下镀速可达12μm/h。The Ni-P coating on zinc alloy prepared by alkaline pre-nickel plating pluse acidic electroless nickel plating was investigated The effects of bath temperature, pH value and main bath ingredients on deposition rate were discussed. The results indicated that the deposition rate increased rapidly with increasing bath temperature and pH value as the plating bath was stable. The peak value of deposition rate, i. e. 12μm/h, could be obtained by optimized electroless nickel plating process.
