Abstract

Titanium alloys are superior of biocompatibility, mechanical properties and chemical stability. The biocompatibility ofTialloy is related to the surface effect between human tissue and implant. Therefore, the purpose of this study is to investigate the bioactivity ofTialloy by alkali and acid chemical surface treatment; and the biocompatibility ofTialloy was evaluated byin vitrotest. Higher bone-bonding ability and bioactivity of the substrate were obtained by the formation of apatite layers on theTialloy in simulated body fluid. The microstructures of apatite layer were investigated by scanning electron microscope (SEM) and the formed phases were analyzed with X-ray diffraction (XRD).
