abstract = "General corrosion was observed on high strength low alloy carbon steel after electrochemical impedance spectroscopy experiments (EIS) performed in H2O saturated with CO2 at 50°C and 15.2 MPa. However, general and localized were observed on the same material surfaces after the EIS experiments performed in supercritical CO2 containing approximately 6100 ppmv H2O at 50°C and 15.2 MPa. The general corrosion areas were uniformly covered by the FeCO3-like phase identified by X-ray diffraction (XRD). In the area of localized corrosion, XRD also revealed FeCO3-rich islands embedded in α-iron. The energy dispersive X-ray (EDX) analysis revealed high concentrations of iron, carbon, and oxygen in the area affected by general corrosion and in the islands formed in the area of localized corrosion. The real and imaginary impedances were lower in H 2O saturated with CO2 than those in the supercritical CO2 containing the aqueous phase indicating faster corrosion kinetics in the former.",
