Study on Porous Titanium Biomedical Materials

摘要：

　　The bioactivity of porous titanium is poor.Alkali treatment and heat treatment were used in porous titanium to induce apatite biocoatings on the surface of porous titanium and improve the bioactivity of porous titanium.The results indicate that grass-blade fibre Na2TiO3 and amorphous rutile form on alkali and heat treatment samples and (102) plane Ti disappeared.Octacalcium phosphate (OCP) and Hydroxyapatite (HA) were found on the surface of samples in simulation body fluid (SBF) for 2w.The intensity of OCP and HA increased with time of samples in vivo increased.Ti-OH formed on the surface of the gel was explained by the point of view of negative and positive ion exchange.The mechanism of formation of OCP and HA induced by Na2TiO3 and TiO2 gel was studied.
