    Usefulness of In-Situ Synchrotron Study on Scale Formation during CO2 Corrosion of Mild Steel: A Review حسب Sk, Mobbassar Hassan

    منشور في 2016
    "…It is the in-situ synchrotron study which made it possible to illustrate the appreciable time lag between the start of supersaturation and critical supersaturation limit. Ingham et al. [2] used in-situ synchrotron small- and wide-angle X-ray scattering (SAXS and WAXS) to demonstrate that the formation of crystalline siderite (FeCO3) during the corrosion of steel in CO2-saturated brine is actually preceded by the formation of a colloidal precipitate and an amorphous surface layer, both assumed to be amorphous ferrous carbonate. …"
