Abstract
The comparison of corrosion mechanism of X70 steel, as well as the formation mechanism of scale, at between 9.5 and 1Â MPa were studied. The outer FeCO3 scale formed at 1Â MPa presented better protectiveness than that at 9.5Â MPa, while the protectiveness of inner layer was just contrary. Under supercritical CO2 condition, localized corrosion occurred at the transitional stage-the amorphous layer evolved into inner FeCO3 scale. General corrosion rate decreased in a logarithm tendency with the Young's modulus of FeCO3 scale. The fracture toughness of scale at 9.5Â MPa was higher than at 1Â MPa.
