Abstract

The effect of cementite morphology on the corrosion layer formation of four high-strength carbon steels was studied in an aqueous solution containing CO₂ and CO₂/H₂S. The linear polarization resistance and weight loss data reveal that as the cementite phase fraction is increased, the corrosion rate increases in CO₂ environment, while no trend is observed in the CO₂/H₂S environment. The results indicate that a porous and, non protective corrosion layer forms in the CO₂ environment, whereas a protective layer forms in the CO₂/H₂S environment. A mechanism that explains the role of cementite morphology on corrosion layer formation in a CO₂ environment is proposed for the studied materials.
