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 TiO2 nanotubes by anodization (P < 0.05). Annealing improved the corrosion resistance of anodized oxidation film on titanium.
Conclusion:
The results of electrochemical examinations indicate that the TiO2 nanotubes by anodization increases the corrosion resistance of titanium.
