Potentiodynamic polarization methods have been extensively used to study the corrosion behavior of a variety of metallic systems. In aluminum alloys, potentiodynamic polarization methods have been used to study corrosion rates and micro-galvanic interactions between the various phases within the alloys. A detailed understanding of the changes occurring on a microstructural level during these corrosion experiments is critical in obtaining a comprehensive understanding of corrosion process. In this study, potentiodynamic polarization was combined with ex situ X-ray microtomography, focused ion beam and scanning electron microscopy, to understand the evolution of corrosion and pitting on the alloy surface at each stage of the experiment. Additionally, the role of grain boundaries and a variety of inclusions with their associated changes in morphology were studied. The correlative microscopy approach used here enabled us to obtain a multi-faceted understanding of the corrosion and pitting process.
