中文摘要：
以钛酸正丁酯为前驱体,采用溶胶-凝胶-水热晶化法在不锈钢（SS）表面制备TiO2纳米膜.利用X射线衍射（XRD）、Raman光谱、场发射扫描电子显微镜（SEM）、原子力显微镜（AFM）和俄歇电子能谱（AES）表征了TiO2纳米膜的晶型、表面形貌和表面化学组成.通过极化曲线和电化学阻抗谱（EIS）研究了TiO2纳米膜的耐蚀性能.170°C下水热晶化制备的锐钛矿TiO2与450°C焙烧制备的锐钛矿TiO2的结晶度类似,但两种TiO2薄膜的表面结构存在明显差异,水热晶化法制备的TiO2纳米膜在3.5%（w）NaCl溶液中的耐蚀性能优于焙烧法制备的.
英文摘要：
Nano TiO2 films were applied to the surface of stainless steel （SS） by sol-gel and hydrothermal crystallization using Ti（O（CH2）3CH3）4 as a precursor. The properties of the TiO2 films were determined by X-ray diffraction （XRD）, Raman spectroscopy, scanning electron microscopy （SEM）, atomic force microscopy （AFM）, and Auger electron spectroscopy （AES）. The corrosion performance of the TiO2 films was evaluated by electrochemical impedance spectroscopy （EIS） and polarization measurements. Anatase TiO2 films prepared by hydrothermal crystallization at 170 °C showed similar crystallization to those prepared by conventional calcination at 450 °C. The TiO2 prepared by the two methods were, however, obviously different from the surface structure and the material prepared by hydrothermal crystallization showed better anticorrosion performance in 3.5% （w） NaCl solution compared with the material prepared by calcination.
