| Research Abstract |
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.
