Surface modification of titanium in the nanometrical range was performed in order to improve both the biocompatibility and the corrosion resistance in the biological media. The presence of anatase and the incorporation of phosphate to the surface film were determined, while the electronic properties of the surface oxide present carrier number in the range adequate for biomedical applications. And the increase in the thickness of the film from 3 to 80 nm was estimated from EIS results, and a bilayer structure of the protective oxide was determined
