Abstract
Iron carbonate (FeCO3) layers influence the electrochemical properties of carbon steel during aqueous corrosion in carbon dioxide–saturated environments. In this study, electrochemical measurements conducted in an autoclave at 80°C and 5 barg are combined with cross-sectional imaging to elucidate interfacial properties of X65 carbon steel at key stages of FeCO3 layer development. The effects of evolving system chemistry are also considered by variation of the X65 surface area to solution volume (A/V) ratio. FeCO3 reduces general corrosion rates through a combination of active site blocking and restriction of mass transport, with resultant layer properties dependent on the A/V ratio.
