Abstract: The Controllable electrochemical deposition has been developed to prepare the hydroxyapatite(HA) coatings on Ti substrate with different morphologies and structures.Three kinds of typical topography of HA coatings,i.e.standing-up,flower and ordered porous structures have been obtained.The XRD and FTIR results demonstrate high crystallinity of the coating and exclusion of other forms of calcium phosphates.In vitro tests reveal that the biological property is largely dependent on the structure and morphology of the HA coating.It has been found that all pure HA coating show good biocompatibilities,while only the HA coating with ordered porous structures exhibits best bioactivities.
