Microradiographic Characterization of Pitting Corrosion Damage and Fatigue Life

Due to the increasing number of aging aircraft, the inspection and assessment of corrosion and fatigue damage on airframe structures is of major concern [1]. Among the different types of corrosion damage, pitting corrosion is an important factor in triggering widespread fatigue crack initiation and reduced fatigue life. Therefore, the ability to predict surface crack origination from pitting corrosion is necessary for timely maintenance of aging aircraft
