| 摘 要： | 研究了在低温熔盐中（低于２００℃）电沉积Ａｌ－Ｍｎ合金镀层成分的控制，镀层化学组成与结构之间的关系以及镀层的耐蚀性能．提出影响镀层锰含量的主要因素是熔盐中锰离子的浓度．镀层含锰量在２５～４０（ｗｔ）％之间可形成非晶态结构．实验表明，Ａｌ－Ｍｎ合金镀层在０．５ｍｏｌ／ＬＨ＿２ＳＯ＿４熔液及ＮａＣｌ溶液中具有优良的耐蚀性，非晶态结构的Ａｌ－Ｍｎ合金镀层的耐蚀性更为优异．

| Abstract: | The Al-Mn alloy plating was electrodeposition from low temperature molten salts(below 200℃),its chemical composition control,corrosion resistance as well as the relationshipbetween chemical composition and structure were studied.The results indicate that the main effect onchemical composition of Al-Mn alloy plating is Mn ion concentration in molten salts.The Mn contentin the range of 25～40(wt)%, Al-Mn alloy plating has amorphous structure. In 0.5 mol/L H_2SO_4and NaCl solution ,corrosion resistance of the alloy plating is much better.When the alloy hasamorphous structure,corrosion resistance of plating has been remarkably increased. |
