Objective To investigate the apatite forming ability of pure titanium implant after micro-arc oxidation treatment in simulated body fluid(SBF) and obtain implants with calcium phosphate(Ca-P) layers. Methods The implants were immersed in(SBF) after micro-arc oxidation treatment for different time lengths, and their apatite forming ability and the morphology and constituents of the Ca- P layers formed on the sample surface were analyzed using X- ray diffraction, scanning electron microscopy, X- ray photoelec...
