【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,Zn-Al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.更多还原

【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,R_p-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.更多还原
