摘要: 为了提高Zn层的耐蚀性,出现了含磷的锌基合金,它具有高的耐蚀性[1,2]且镀层的耐蚀性.我们曾在锌磷合金镀液中加入Co2+离子获得耐蚀的Zn-Co-P合金,并在Pt电极上研究了电沉积Zn-Co-P合金的阴极行为[3].本文介绍了在铜电极上采用循环伏安法[4]研究Zn-Co-P合金电沉积的电化学行为,探讨NaH2PO2对Zn-Co合金电沉积行为的影响。

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.
