| 摘 要： | 研究了微量元素Ｃｕ、Ｆｅ、Ｃｒ对高速电镀ｚｎ－Ｎｉ合金的影响并探讨了其作用机理。Ｃｕ２＋在Ｚｎ－Ｎｉ镀液中容易析出，但它是一种有害元素；Ｆｅ２＋、Ｃｒ３＋则难于析出，镀层中含适量的Ｆｅ、Ｃｒ可提高Ｚｎ－Ｎｉ镀层耐蚀性。同时还探讨了微量元素电沉积机理，提出了微量元素从Ｚｎ－Ｎｉ镀液中电沉积进入镀层的定量判定方法。

| Abstract: | The influences of trace elements Cu,Fe,Cr on high speed Zn-Ni alloy electroplating and their mechanism have been investigated.The Cu2+ in Zn-Ni electrolyte can easily deposit,but it is a harmful element;while Fe2+ and Cr3+ are difficult to deposit.The Fe and Cr in deposit can increase the corrosion resistance of Zn-Ni deposit.The electrodepositing mechanism of trace elements has been discussed,and the quantitative predication method for wheather trace element can deposit from electrolyte has been established. |
