Fabrication of CTP/HAp novel gradient composite bioceramics
Calcium-titanium-phosphate(CaTi4(PO4)6,CTP)/hydroxyapatite(HAp) is a kind of novel gradient composite bioceramics,which has excellent biocompatibility and bioactivity.CTP ceramic film was synthesized one-step on the surface of titanium using micro-arc oxidation(MAO).The CTP/HAp composite bioceramics were prepared by soaking CTP film in HAp inducing solution for several days.XRD,SEM and EDX were used to characterize the bio-ceramic films phase and composition,morphology and component.The influence of electrolyte molar ratio of Ca to P and the current density to the synthesis of film was studied,and the optimized value of parameters above were 1/6 and 15A/dm2.The parameters of HAp inducing solution,such as component and pH value were also studied and the best pH value which is adjusted by NaOH is 6.4.
