The objective of this proposal is to develop a portable and accurate means of detecting and accurately characterizing corrosion in multiple layered structures made of dissimilar metals. The proposed approach is to apply technology that was developed for ultrasonic imaging. Of particular interest are aircraft structures such as wings that are made dissimilar metal layers. The objective is to demonstrate the ability to detect corrosion between layers of material without requirements for disassembly.
