Abstract
Calcium titanate (CaTiO3) and CaO-rich calcium titanate compound films were prepared by laser chemical vapor deposition (CVD), and the change in morphology by immersion in simulated body fluid was investigated. At the Ca/Ti supplying ratio (RCa/Ti) of 0.9 and the laser powder (PL) of 60 W, CaTiO3 film having pyramidal facets in a cone-like morphology was deposited, whereas at RCa/Ti = 1.6 and PL = 60 W, Ca-rich calcium titanate compound film with a cauliflower-like morphology was formed at the deposition rate of 225 μm h-1. By immersion in Hanks' solution for 259.2 ks, the Ca-rich calcium titanate compound film exhibited the significant formation of calcium phosphate granules covering the film surface, while a small amount of calcium phosphate precipitates was partially formed on the CaTiO3 film surface.
