Summary:Title screen
We have studied the feasibility of improving the functionality of composite titanium implants by modifying their oxidized surface with the aim of imparting it bioactive properties. The growth of a structured calcium silicophosphate layer on an oxidized titanium surface by a sol-gel process has been shown to significantly change its morphology, ensuring porosity and a specific surface area as large as 18.0 ± 0.5 m2/g. Owing to the sol-gel derived film, the surface of the titanium coating acquires hydrophilicity, as well as adsorption and chemical activity, due to surface centers having an excess charge: SiO-Hδ+ and Si-OHδ-. Interaction of the surface with an SBF solution leads to the formation of amorphous and crystalline calcium phosphates on it. Our results suggest that oxidized titanium implants coated with a sol-gel derived film will exhibit bioactive behavior under the conditions of a living organism.
