TITANIUM OXIDE NANOTUBE ARRAYS USED IN IMPLANT MATERIALS

Electrochemical self-ordering has been recognized as one of the most attractive synthetic approaches for fabrication of highly ordered nanotube materials from a variety of metals and semiconductors. This work presents synthesis of the self-organized TiO2 nanotube arrays by electrochemical anodization in fluoride/glycerol electrolyte. Scanning electron microscopy and X-ray diffraction were carried out to characterize the well-ordered titanium oxide nanotubes. The corrosion of pure titanium and anodized titanium were tested in synthetic body plasma solution at 37 +/- 1 degrees C, using potentiodynamic polarization. It was shown that anodized titanium exhibits superior corrosion resistance compared to pure titanium.
