Forming titanium oxide on low young's modulus titanium alloy by ECR plasma oxidation for developing biomechanical implant

在建立了电子回旋共振（ECR）等离子体氧化在纯钛表面形成氧化钛膜的表面改性方法后，我们在不同压力和温度下成功地在杨氏模量接近人体骨的钛合金表面形成了同样的膜。此外，细胞培养显示，成骨细胞分化也在该二氧化钛膜上增强。该方法有望成为改善种植体-骨界面钛合金力学性能和生物相容性的一种表面改性方法。

After establishing the surface modification method of forming titanium oxide film on pure titanium surface by electron cyclotron resonance (ECR)plasma oxidation, we have achieved success in forming the same film on titanium alloy which young's modulus is close to human bone at various pressures and temperatures. Furthermore, cells culture showed that osteoblastic differentiation was also enhanced on this titanium dioxide film. It has the potential to become a surface modification method in improving the mechanical properties and biocompatibility of titanium alloy close to body bone tissue in implant-bone interface.
