Abstract

We dveloped a novel method for titanium coating material using modified thermal decomposition technique, specifically focusing on presence of CaTiO 3 and carbon C. Two layers of thin film coating composed of CaTiO3-amorphous carbon compound (CaTiOa-aC) and hydroxyapatite (HA) were generated on titanium surface. In this method, ratios of Ca/P as well as Ca/Ti, sintering temperature and sintering velocity were carefully planned. Within crystal structure of CaTiO3 granules, 4 atomic % of carbon in amorphous state was included. By our method, inclusion of carbon in HA suggested formation of carbonate apatite. Regarding with attachment-detachment experiment at titanium surface, adhesion strength was 2.5 times stronger in CaTiO 3aC/HA coating substrate as compared to HA only coating material. Results of the novel developed modified thermal decomposition method suggested that the 2 layers biomaterial composed of CaTiO3-aC (0.6 μm) and carbonate apatite-included HA (2.4 μm) can be used as a coating material on titanium surface.
