Abstract

In this study, the corrosion behavior of the AA2198-T851 and its friction stir weldment was used to show the qualitative use of potentiodynamic polarization and the effect of anodic hydrogen evolution (AHE). 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, AHE interferes 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.
