Abstract In simulating the environment of CO2 corrosion in oilfield,the XRD，EDS and SEM techniques were adopted to study the formation an d development of CO2 pitting corrosion on N80 steel.The results demonstrated t hat Cl- anions could be enriched and nucleated at the interface between corros ion scale and matrix,which subsequently catalyzed the formation of pitting.Where as pits could also be enriched by Cl- forming approximately 3 μm enrichment l ayer at interface,thus leading to the further development of pitting.In present case,the relationship between mechanisms of anodic reaction and morphology of pi tting was discussed.
