| 摘 要： | 着重研究了Ａｌ含量顺次递增的３种组分，Ａｌ－Ｔｉ合金阳极氧化膜的化学组成及微观结构。用ＸＰＳ俗分析表明：氧化膜是由Ａｌ２Ｏ３和ＴｉＯ２组成，经ＡＥＳ深度剖面分析得到了两者之间的比例，并推理出膜的微观结构模型，用ＳＥＭ观测了３种膜的表面形貌，清楚地看到：合金组分不同，膜的致密度不同。ＸＲＤ实验证明：氧化膜的晶型较复杂，且有取向。

| Abstract: | The Chcmical compositions and microstructure of anodic oxide films on three types ofAl-Ti alloy samples with Al content increasing one after another were investigated. The ox-ides were examined with X-ray photoelectron spectroscopy(XPS).It was shown that the an-odic films were composed of Al2O3 and TiO2.The ratio of Al2O3 to TiO2 in films in directionof its thickness were obtained by Auger electron spectrospy(AES).The microstructural mod-el of the anodic films was proposed.Surface morphlogies of three types alloy of films wereobserved by means of scanning electron microscope(SEM)in order to find out the relationspipbetween dielectric properties of films and the microstructure. From XRD patterns.it was con-firmed that this kind of anodic oxide films were crystalline. |
