Abstract:
Effects on surface microstructure and mechanical property of pure titanium (TA1) for implant treated by anodic oxidation were investigated. We found that the oxide film with a certain uniform and compact color could be achieved by anodic oxidation method. However, with the increasing of oxidizing voltage and time, the oxide film will be dissolved at local area. The oxygen content of oxide film and the hydrogen content of matrix titanium will be raised, and will also be increased. In fact, hydrogen could be diffused into matrix titanium. With the increase of hydrogen content of matrix titanium and sigmas/sigmab, there appear the possible results of plastic deformation and the fracture of implant.
