Surface Modification of Titanium by Hydroxyapatite/Al2O3 Porous Bioceramic Coating
摘要
Abstract
A hydroxyapatite (HA)-Al-chitosan (CS) composite bioceramic coating was widely applied to the surfaces of pure titanium by the electrophoretic deposition (EPD) method.The mechanism of EPD of HA/Al/CS composites was discussed.The porous HA/Al2O3 coatings were obtained as average pore diameter of 5μm after the heat treatments with temperatures 700℃ for 2h in air.This approach is especially attractive for the fabrication of polymer-ceramic composites,where CS can provide porous coating,whereas Alprovide Al2O3 to improve the coating adherence.The adhesive force between the HA/Al2 O3 porous coatings and pure titanium was approximately 30.5MPa.The porous HA/Al2O3 coatings provide improved bioactivity and biocompatibility of pure titanium in the simulated body fluid solution.关键词
