説明

In this study, effects of the anodizing condition on the bonding strength and the damping properties of the bonding specimen were investigated. The specimens bonded Ti–6Al–4V alloys to AZ31 magnesium alloys with epoxy resin adhesives were used. A porous anodic oxidation film of about 4 μm thickness was formed on the Ti–6Al–4V alloy surfaces by anodizing. The Vickers hardness of anodized Ti–6Al–4V alloy specimen was increased two times higher than that of non-treated specimen. And then, the bonding strength measured by the adhesion tester was also increased. The damping characteristics of bonded specimen were examined through experiments of the collision sound and the reaction velocity of pendulum. As a result, in comparison to the no-treated specimen, the damping performances of anodized Ti–6Al–4V titanium alloy specimens were increased and restitution coefficients of that were decreased. On the other hand, the tonal component of the AZ31 magnesium alloy was reduced in the lower register below 1 kHz. It was also demonstrated that the damping performance of the bonding specimen was improved depending on the anodic oxide coating and adhesive.
