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

    منشور في 2016
    "…However the associated mechanism was not clearly understood until in-situ synchrotron x-ray diffraction study revealed a clearer picture of the mechanistic aspect of the expedited siderite film formation in presence of traces of Cr3+[2, 5]. This recently done in-situ synchrotron study made it clear that traces of Cr3+ in the solution significantly expedites the precipitation rate of the colloidal precursor and thus accelerate the appearance of the crystalline scale through its catalyzing influence on the nucleation process by modulating the local pH level at the steel surface and thus reducing of the critical supersaturation for precipitation. …"
