Abstract

In this study we investigate the effect of corrosion damage of Aluminum (Al) on the impedance response of piezoelectric sensor attached to the Al. The piezoelectric sensor had a square geometry with fundamental planar mode. A basic environment (NaOH) was used to induce corrosion damage on the Al 6061 grade. A systematic variation in the real part of the electromechanical impedance was found as the specimen corrosion proceeded. The results also indicate that there is an optimal distance between the piezoelectric sensor and the location where damage is occurring that provides highest damage index.
