Influences of Trace Elements on High Speed Zn-Ni Alloy Electroplating

    Graphical Abstract
    • 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.
