Abstract

Titanium and its alloys are extensively used as orthopedic, cardiovascular devices, and dental implants. Several devices such as 316L SS, Co-Cr alloys are used as implants of which titanium implants have received more attention due to their bio inertness, and bone-forming capacity between bone tissues and implants. Besides its advantages, the traditional Titania faces some complications such as loosening of implants and infections, which leads to implant failure. Hence, the problems related to implant failure are to be overcome to meet the current requirement. In the present investigation, TiO2 film was achieved on the surface of Ti-6Al-4V by anodization method at 20V for 1 hour in the presence of H3PO4/NH4F solution as electrolyte. The specimen was dried and annealed at 600oC for 4 h. (XRD) and EDAX analysis of the annealed Ti-6Al-4V samples confirmed the formation of TiO2 on their surfaces. The structural morphology and topography of the TiO2 layer formed on the implant surface were characterized using (SEM). Electrochemical impedance spectroscopy and polarization plots confirmed the improvement of the corrosion resistance with TiO2 growth on the implant surface. Such TiO2 arrays can be useful as a well-adhered bioactive surface layer on Ti implants for orthopedic and dental implants.
