钛表面阳极氧化膜的腐蚀行为研究
Study of corrosion behavior of titanium with anodized oxidation film
摘要
Abstract
Objective To investigate the variation of the corrosion resistance of anodized oxidation film on titanium by electrochemical methods. Methods TiO2 nanotube layer was formed on Ti surface by anodization. The morphology was observed with scanning electron microscope(SEM) and the crystal phase was analyzed using X-ray diffraction(XRD) before and after annealing. Polarization curves were examined by electrochemical methods. Results Titanium oxide nanotubes with 80 nm diameter and 400 nm length was seen on Ti after anodization. The annealing nanotubes was anatase crystalline phase by X-ray diffraction analysis. The self-corrosion potential and break-down potential of smooth Ti were significantly lower than TiO2 nanotubes by anodization (P＜0.05). The self-corrosion current and passived current were significantly higher than Ti02 nanotubes by anodization (P＜0.05). Annealing improved the corrosion resistance of anodized oxidation film on titanium. Conclusion The resuIts of electrochemical examinations indicate that the TiO2 nanotubes by anodization increases the corrosion resistance of titanium.关键词
