| Outline of Final Research Achievements |
It was found that an electrolytic treatment on titanium alloys was effective to improve the corrosion resistance. The purpose of this research was to investigate the effect of the surface treatment conditions on the corrosion resistance and the fracture resistance of the titanium alloy specimens combined with indirect composite materials for esthetic dental prostheses. As a result, corrosion resistance of Ti-6Al-7Nb alloy was markedly improved by this electrolytic treatment, and the maximum bending strength of the combined specimens increased when treated with the primer including thiouracil type monomers. Fracture energy and deflection were also high for this condition, however, stiffness of the specimens increased when treated with an organophosphate type monomers, which suggested that the influence on the mechanical properties was varied with the treatment conditions.
