Role of cementite morphology on corrosion layer formation of high-strength carbon steels in sweet and sour environments

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