The results showed that some details can be revealed in the anodic arm of the polarization curves of an Al alloy above the breakdown potential with changes in cell configuration and electrolytes. In addition, AHEinterferes with the measured current density in the anodic arm, which in turn can be used to assess the extent of corrosion susceptibility and changes in anodic dissolution behavior of the alloy.1-14closedAccesshydrogencorrosionanodizationpolarizationaluminium alloyscopper alloyslithium alloysscanning electron microscopyArtigo de periódico10.1002/maco.201810108https://orcid.org/0000-0002-4987-333441.7057.33
