The exfoliation corrosion (EC) is a well known degradation mode of several
aluminum alloys, strongly dependent on aging conditions and on morphological
parameters of the microstructure. It occurs exclusively in microstructures
composed of plate-like or fibrous grains, typical for rolled plates and sheets. It
consists in an intense corrosion (inter- or transgranular) with propagation paths
parallel to the rolling surface, followed by the material disintegration through
'exfoliation' (Fig. 1).
