Formation of TiO_2 Coating Layer on the Surface Treated Ti Alloys

摘要

Pure Titanium alloys are superiorities of biocompatibility, mechanical properties andchemical stability. The biocompatibility of Ti alloy is related to the surface effect.In this study, Ti Alloys were treated by alkali and acid activation process. And through the solcoating layer, biocompatibility were investigated.Consequently, it appeared that the porous layer was generated on the surface of alloy by surfacetreatment and sol coating process. It was found that with surface treatment on Ti alloy, theformation speed of porous was much quicker compared with those ones without treatment.Therefore, the biocompatibility was improved.
