摘要： 采用两步法在AA6061铝合金表面制备了钛锆-氨基三甲叉膦酸盐复合膜.用扫描电子显微镜分析了钛锆-氨基三甲叉膦酸盐复合膜的形貌特征;用红外光谱分析了复合膜的化学结构;用X射线光电子能谱分析了复合膜的化学结合状态;用中性盐雾试验测定了复合膜的耐蚀性能.结果表明:钛锆-氨基三甲叉膦酸盐复合膜是由钛锆钝化膜与氨基三甲叉膦酸盐膜相杂化构成的复合膜.钛锆-氨基三甲叉膦酸盐复合膜经72 h盐雾腐蚀后,腐蚀面积小于10%.

Abstract: The titanate-zirconate phosphonate hybrid films were prepared by two-step method on AA6061 aluminum alloy for corrosion resistance. The morphology of those films was investigated by SEM with the chemical structure analyzed by Fourier transform infrared spectroscopy. Furthermore, the phase composition was examined by X-ray photoelectron spectroscopy with the corrosion resistance performance tested by salt spay test. The results showed that the titanate-zirconate aminotrimethylene phosphonate films are of hybrid/composite structure that is composed of the titanate-zirconate film and aminotrimethylene phosphonate layer. The corrosion area of the hybrid film is less than 10% after continual salt spay for 72 hr.
