研究了Zn-Ni-TiO_2复合镀层的电沉积工艺，讨论了镀液组成及工艺条件对镀层的影响．结果表明，在氯化钾镇液中能获得0．4％～2．1％的二氧化钛固体微粒和1．2％～3．1％的镍的光亮细致复合镀层．镀层钝化膜色泽鲜艳，耐蚀性能是普通镀锌层的2～4倍．
The electrodeposition process of Zn-Ni-TiO 2 composite coating was studied. The influence of bath composition and process conditions on the coating was discussed. The results showed that bright and fine composite coatings of 0.4% ~ 2.1% titanium dioxide solid particles and 1.2% ~ 3.1% nickel were obtained in the potassium chloride solution. Passivation film bright color coating, corrosion resistance is galvanized ordinary 2 to 4 times.
