摘　　要：采用双镀法制备了Zn-10%Al-Mg镀层钢丝,用ICP-AES分析了镀层的化学成分,用SEM观察了镀层的组织结构,采用中性盐雾试验评价了镀层钢丝的耐蚀性,并与锌镀层钢丝进行了比较。结果表明:Zn-10%Al-Mg镀层钢丝的腐蚀质量损失率约为锌镀层钢丝的六分之一,Zn-10%Al-Mg镀层钢丝的耐蚀性远远优于锌镀层钢丝的。Zn-10%Al-Mg coated steel wire was prepared by dual hot dipping method. The chemical composition and microstrueture of the coating were analyzed by ICP-AES and SEM. The anti-corrosion property of the Zn-10%Al-Mg coated steel wire was also analyzed by neural salt spraying test （NSST） method, and compared with that of zinc coated steel wire. The results show that the weight loss rate of Zn-10%Al-Mg coated steel wire was one-sixth of that of Zn coated steel wire, so the anti-corrosion property of Zn-10%Al-Mg coated steel wire was highly superior to that of Zn coated steel wire.
