Abstract
A non-destructive testing apparatus generates an electric current in a test coupon that is adjacent to the metallic structure. The non-destructive testing apparatus measures the electric current to produce at least one electric current measurement. The non-destructive testing apparatus correlates the at least one electric current measurement with the quantity of a predetermined iron oxide in the test coupon to determine a proxy for the degree of alternating current interference corrosion in the metallic structure.
