Abstract: The electrodeposition behaviour of Zn-Co-P alloy on Copper Electrode has been studied with cyclic voltammetry. It is shown that the cathodic polarization of Zn-Co alloy increases, if NaH2PO2 has been added into the electroplating solution and that the anodic disso-lution peak potential of Zn-Co-P alloy has shifted to positive potential in comparison with those of Zn, Zn-P alloy and Zn-Co alloy, therefore, the corrosion resistance of Zn-Co-P alloy increases.

Key words: copper electrode, zinc-cobalt-phosphorus alloy, electrodeposition
