Abstract
The general and localized corrosion of X65 carbon steel in CO2-saturated environments conducive to iron carbonate (FeCO3) formation has been studied using electrochemical measurements, together with post-test surface analysis. This research offers new insights into the evolution of FeCO3 layer and its link to the subsequent initiation and propagation of localized corrosion. We identify crevice-like regions forming at boundaries/edges of the FeCO3 crystals, which constitute the crystalline layer, where small cavities filled with electrolyte are restricted between developing crystals. It is apparent that such crevice-like features act as precursors to the localized/pitting corrosion on carbon steel over longer durations. Data availabilityThe raw/processed data required to reproduce these findings cannot be shared at this time as the data also forms part of an ongoing study.
