Resumo
In this work, the corrosion behavior of the AA4006 alloy made by the twin roll
caster process was evaluated using electrochemical impedance spectroscopy
(EIS), anodic potentiodynamic polarization curves, and scanning electron
microscopy (SEM). This alloy belongs to the Al–Fe–Si system and is present with
higher amounts of Fe and Si than AA1050 aluminum. Electrochemical tests
were performed in a sulfate solution with or without chloride ions, and two
different areas of the AA4006 alloy were tested: at the surface and at the center
of the sheet (half thickness). The results obtained were compared to the
commercially pure AA1050 aluminum. Electrochemical tests carried out using
the solution without chloride ions presented similar results; however, the
addition of chloride ions resulted in localized corrosion in all samples. It was
possible to compare the corrosion behavior of the studied materials analyzing
these electrochemical data and the micrographs obtained by scanning electron
microscopy.
