摘　　要：为进一步提高Zn—Mn合金镀层的抗蚀性，采用锌锰系磷化处理Zn—Mn合金镀层，研究表明在相同镀层厚度下，Zn—Mn合金镀层抗蚀能力是镀锌层的5倍，经磷化后的Zn—Mn合金镀层的抗蚀能力是镀锌层的7～8倍。实验结果表明，Zn—Mn合金镀层经锌锰系磷化后抗蚀性明显提高。The phosphating technology of Zn-Mn alloy coating was studied. The results show that： under some coating thickness, corrosion resistance of Zn-Mn alloy coating is 5 times of that of zinc coating. After phosphating, the corrosion resistance of Zn-Mn alloy coating is 7～8 times of that of zinc coating. The corrosion resistance of the phosphating Zn-Mn alloy coating is enhanced obviously.
