| 摘 要： | 在碱性锌酸盐镀锌液中加入氧化铝和自制添加剂，获得了光亮Zn-Al合金镀层.采用中性盐雾实验、5％氯化钠溶液浸泡实验、电偶腐蚀实验、循环伏安曲线图和Rp-t曲线对Zn和Zn-Al合金的耐蚀性进行了探讨，结果表明，ZnAl合金镀层的耐蚀性优于锌镀层的耐蚀性，可用作钢铁件高耐蚀性镀层.

| Abstract: | A bright zinc-aluminum alloy coating was obtained by electroplating from alkaline zincate solution with addition of alumina and home-made additive. By means of neutral salt spray, 5% sodium chloride immersion test, couple corrosion test, Rp-t curve and cycling volt-ampere curve, the corrosion performance of the coating was studied. The results showed that the corrosion resistance of zinc-aluminum alloy coating was better than the zinc coating. It can be used as a high corroison resistance coating for iron and steel. |
