摘要：
A bioactive coating with no cracks was produced on the porous titanium by alkali-heat treatment. The morphology, element content and phase composition of the coating were analyzed by SEM, XRD and XPS. It is found that a micro-network structure mainly composed of bioactive sodium titanate and rutile covers the interior and exterior of porous titanium cells. And bioactive network without cracks is achievable with a given set of process parameters of the alkaline solution concentration and alkali-heat treatment time. After immersion into the SBF solution for 3 d, a carbonate-hydroxylapatite was detected by XRD on the cell surface of the porous titanium, showing a good compatibility of the porous titanium with bone.
