AB Scanning electrochemical microscopy in feedback mode was used to monitor changes inthe surface state of a polymeric film applied on a metallic substrate when exposed to anaqueous electrolytic environment. The protected metal consisted of a carbon steelsubstrate coated with a polyurethane-based polymeric film. SECM measurementsperformed in the presence and absence of chloride anions permitted a specific effectcaused by Cl- anions at early exposures to be detected. Significant surface roughening isobserved for immersion times shorter than one day when the electrolyte contains chlorideions. Additionally, the growth of an individual blister could also be investigated
