We developed a novel method for titanium coating material using modified thermal decomposition technique, specifically focusing on presence of CaTiO3 and carbon (C ). Two layers of thin film coating composed of CaTiO3-amorphous carbon (CaTiO3-aC) and hydroxyapatite (HA) were generated on titanium surface. Regarding with attachment-detachment experiment at titanium surface, adhesion strength was 2.5 times stronger in CaTiO3-aC/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 mm) and HA (2.4 mm) can be used as a coating material on titanium surface
