We developed a novel method for titanium coating material using modified thermal decomposition technique, specifically focusing on presence of CaTiO3 and carbon. Two layers of thin film coating composed of CaTiO3-amorphous carbon compound (CaTiO3-C) and hydroxyapaptite (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% of carbone 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 CaTiO3-C/HA coating substrate as compared to HA only coating material. Results on the novel developed modified themal decomposition method suggested that the 2 layers biomaterial composed of CaTiO3-C (0.06mm) and carbonate apatite-included HA (2.4mm) can be used as a coating material on titanium surface.
