Resumo
In this study, special attention was given to the characterization of pits on
the anodized aluminum alloy (Al–Zn–Mg–Cu) with an anodic aluminum
oxide formed in tartaric sulfuric acid. Anodic polarization in 0.1 mol L−1 NaCl
solution was used to initiate pitting corrosion in the anodized alloy. Pit
characteristics, such as morphology and depth, were evaluated by using optical
microscopy and optical profilometry, and scanning electron microscopy. The
methodology adopted in this study revealed severe under‐film pitting due to
highly occluded conditions and showed that the extent of the under‐film pitting
is significantly greater than the size of pit mouth observed from the surface.
