摘　　要：经ＡＭＴ复合物处理的青铜表面上形成的保护膜，通过电化学方法、盐雾试验、湿热试验和盐水浸渍试验结果表明其耐蚀性优于ＡＭＴ和ＢＴＡ在青铜上形成的膜。ＡＭＴ复合物已应用于战国时期青铜文物保护中，使青铜文物呈现“不改变文物原貌”的要求，并将此青铜文物置于冷热和干湿的环境下，历经４ａ观察，未发现任何变化。此外，通过ＸＰＳ、ＡＥＳ和ＳＴＭ分析表明ＡＭＴ及其复合物在青铜表面上形成保护膜的结构为Ｃｕ｜Ｃｕ２Ｏ｜Ｃｕ＋ＡＭＴ，并由ＳＴＭ分析观察得到膜的微观结构特征是由一种结构单元呈线性，各线型结构单元之间是相互平行或呈一定角度排列在青铜表面上，且层与层之间是交错排列的致密的有机络合聚合物膜。The corrosion resistance of protective films,formed on the bronze surface by AMT treatment and AMT complex reagent treatment,was studied by using the methods of electrochemical measurement,salt spraying rest,wetheat and salt dipping test. The results showed that the corrosion resistance of protective films by AMT complex reagent treatment was better than that by AMT or BTA.The AMT complex reagent treatment was applied to protect a bronze ware of the Warring States.This bronze ware has been preserved in coldheat and drywet environment and its appearance remains unchanged for four years.That can meet the cultural relics preservation requirements.In addition,the analyses of XPS,AES and STM showed that the structure of protective films formed on the bronze surface by AMT and its complex reagent is Cu|Cu2O|Cu+AMT.Furthermore,the microstructure characteristics of the films were known through STM analysis as that the structure units of films are liner and arranged on the broze surface at certain angle or b
