摘　　要：采用Fe(NO_3)_3溶液对阳极氧化法制备的TiO_2纳米管阵列进行掺杂改性。采用扫描电子显微镜(SEM)、能谱(EDS)和X射线衍射(XRD)等手段研究了改性前后试样的表面形貌、元素组成和微观结构。利用电化学分析研究了纳米管掺杂前后的耐腐蚀性能。结果表明,掺杂溶液浓度对掺杂纳米管的表面形貌、微观结构和电化学耐蚀性能影响较大,掺杂溶液浓度较低时所获得掺杂纳米管的耐蚀性能较好。TiO2 nanotube arrays prepared by means of anodic oxidation methods were doped by using Fe （NO3 ）3 solution with various concentrations. The surface morphology, chemical composition and mierostructure of the prepared samples were investigated by using scanning electron microscopy （SEM） , energy dispersive spectrometer （EDS） and X-ray diffraction （XRD） , respectively. The results show that the doping solution concentration has a great influence on the surface morphology, microstrueture and electrochemical corrosion resistance of the doped nanotubes. The corrosion resistance of the doped nanotubes is better when the doping concentration is lower.
