摘　　要：Ｘ光电子能谱（ＸＰＳ）分析表明，电镀Ｚｎ－Ｃｏ合金钝化膜与电镀锌钝化膜一样，均由ＣｒＯ_３、Ｃｒ_２Ｏ_３、Ｚｎ（ＯＨ）_２、ＺｎＯ及Ｈ_２Ｏ等组成，但Ｚｎ－Ｃｏ合金钝化膜中高价铬含量较高，且在钝化膜的较深层处有原子态钴存在，这是该合金钝化膜具有高耐蚀性的主要原因。The results of XPS for passivative film on Zn-Co alloy electrodeposits are the same as that for passivative film on Zinc deposits. They are composed of CrO_3、Cr_2O_3、Zn(OH)_2、ZnO and H_2O. However, the content of high valent chromium in the passivative film on Zn-Co alloy deposits is higher. The film contains some atomic cobalt in the depth of it and this is the main reason of its high corrosion resistance.
