以Ca(α)2和(C6H5O)3PO为前驱体，采用MOCVD方法在工业纯钛(Cp-Ti)表面制备了α-TcP和HAP薄膜。通过将样品浸泡在Hanks‘s溶液中，研究了Ca-P-O涂层上磷灰石的形成行为。在α-TCP涂层上，1d后有磷灰石相再生，14d后覆盖整个试件表面，1h后再生出磷灰石相，6h后覆盖整个表面。HAP涂层上再生的磷灰石相在12h后由针状结构转变为网状结构。
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 (C 6 H 5 O) 3 PO 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 14 d. 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.
