Abstract Aluminum (Al) corrosion starts off at the micron or even submicron scale and if it is coating protected, occurs metal‐coating interface. These events are by large studied using bulk measurements making understanding incomplete due to its micrometric occurrence. This gap therefore targeted in current study a combination of SECM mapping modes together with new strategy employing redox‐mediator mixtures. combinations allow exploration both Al surface topographic features as well hotspots. Nine differently finished AAxxxx surfaces (namely, AA5083‐rolled‐Zr, AA6061‐rolled‐Zr, AA6061‐grinded‐Zr, AA6111‐rolled‐Zr, AA6111‐grinded‐Zr, AA7075‐grinded‐Zr, AA7075‐rolled‐Zr, AA7075‐rolled‐ZnPh sealer without sealer) investigated their as‐received state for mapped on 1 mm 2 high precision. The most interesting outcome that typically grinded samples show more cathodic higher number resultant maps then quantified extract hotspots correlate them outcomes real‐life road tests performed years. investigations present strong predictive strategy, which makes this comprehensive highly applicable sectors like automobiles aerospace) surfaces.
