Abstract

Ca-P-O coatings of α-tricalcium phosphate (α-TCP) and hydroxyapatite (HAp) films were prepared on commercially pure Ti (CP-Ti) by MOCVD using Ca(dpm)2 and (C6H5O)3PO precursors. The behavior of apatite formation on the Ca-P-O coatings was investigated by immersing specimens in a Hanks solution. An apatite phase has regenerated on the α-TCP coating after 1 day, and has covered the whole specimen surface after 14d. On the HAp coating, an apatite phase has regenerated after 1 h and has covered the whole surface after 6h. The microstructure of the regenerated apatite phase on the HAp coating has changed from a needle-like to a network texture after 12h.
