Corrosion in light metal alloys is complex due to the simultaneous interaction of variables such as chemical composition, microstructure, corrosive environment (composition, pH), and temperature. It is also vital to understand how each of these factors contribute towards corrosion at multiple length scales. In this talk, we will discuss about the combination of multimodal corrosion with multiscale imaging to probe the corrosion behavior of light metal alloys. Using examples of joining of Al alloys and coatings for corrosion protection of Magnesium alloys, we will elaborate on the application of bulk and local electrochemical methods with ex situ and in situ imaging. This approach has yielded several interesting insights into the role of metallurgical phases and microstructural defects that contribute to local and global corrosion damage. Finally, the role of these multimodal electrochemical analyses in guiding corrosion mitigation will be discussed.
