CO2 corrosion behavior and atomic processes at corroding interface of a high strength low alloy tempered martensite tubular steel were investigated for 168 h at 70 and 80 °C using electrochemical and surface evaluation techniques. Linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS) were applied to assess the corrosion rate and evolution of atomic processes and interfacial phenomenon. Corrosion rate increased at the beginning to a maximum then it declined with time at both temperatures. Variation of pH was monitored for the test duration and it changed from 3.78 at the beginning to 5.79 and 5.92 for 70 and 80 °C respectively. EIS measurements and equivalent circuit modeling demonstrated the formation of a porous scale upon beginning of experiments. Increase in charge transfer resistance with time indicated decrease in porosity of scale and increasing its protectiveness. X-ray diffraction analysis did not detect formation of iron carbonate in these conditions.
