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

在建立了用电子回旋共振（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，我们成功地在不同压力和温度下在钛合金上形成了杨氏模量接近人骨的氧化钛膜。此外，细胞培养表明，在这种二氧化钛薄膜上，成骨细胞分化也得到了增强。它有可能成为一种改善钛合金靠近人体骨组织在种植-骨界面的力学性能和生物相容性的表面改性方法。

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.
