The foil penetration technique was used to study pit growth in AA 1100-O and AA 2024-T3.Preliminary work on AA 1100-O foils of different thicknesses indicated that the pit growth rateincreased with increasing applied potential, suggesting that pit growth was not under transportcontrol. Foil penetration experiments were also carried out on AA 2024-T3 foils of a giventhickness, at open circuit as well as anodic potentials. Dichromate ions and other oxidizingagents were added to some test...
