Abstract

In the present study, atomic force microscopy, contact angle instrument and the nano-indentation were conducted to evaluate the effects of oxide layers on TiNb alloys with and wiout surface treatment (TiNb, A-TiNb and AC-TiNb). In addition, the biomechanical properties of TiNb, A-TiNb and AC-TiNb were evaluated by finite element (FE) computer simulations. The results revealed that the rough surface and wettability property of TiNb alloy could be obtained after surface treatments. Furthermore, the surface properties of TiNb, A-TiNb and AC-TiNb are all relative the surface treatments. The elastic modulus of AC-TiNb was reduced to be closed to that of bone tissue. The gradual mechanical properties existed on the TiNb treated samples. The phenomena that more stress shared by bone tissue with treated metallic screws were showed in FEM models. In conclusion, the oxide layers formed by anodization with cathodical pretreatment played an important role in enhancing the biocompatibility and biomechanical ability of TiNb alloys. These results demonstrated that new AC-TiNb alloys not only contain nontoxic constituents but have relatively suroerior biomechanical capability as well.
