| 摘 要： | 利用阳极氧化法制备TiO2薄膜，并研究了薄膜的光电化学防腐作用．XRD和SEM分析表明TiO2薄膜由非晶和锐钛矿组成．其表面形貌较为粗糙．在紫外光的照射下，测试了薄膜在模拟海水中的电极电位、极化曲线、电化学阻抗谱以及与碳钢的耦合电流．结果表明TiO2薄膜对碳钢在模拟海水中的腐蚀具有较好的光阴极保护作用．

| Abstract: | The photo-electrochemical anticorrosion effect of the TiO_2 films was investigated in 3% NaCl solutions.The TiO_2 films were prepared by using anodization method in alkaline solutions.X-ray and SEM analyses indicated that the TiO_2 films were composed of amorphous and crystalline anatase,and the surface was very rough.Under UV illumination in man-made sea water,the polarization curves and impedance spectrum of TiO_2 and coupling photo-current curve between TiO_2 film and 45# carbon steel were measured.The results showed that the anodic TiO_2 films had photo-electrochemical anticorrosion effect for carbon steel under UV illumination. |
