Exfoliation is characterized by leafing or splitting off of alternate layers of thin, relatively uncorroded metal and thicker layers of corrosion product that are more bulky than the metal from which they came ( Fig. 7 ). The layers of corrosion products cause the metal to swell. In an extreme case, a 1.3 mm...
