Usefulness of In-Situ Synchrotron Study on Scale Formation during CO2 Corrosion of Mild Steel: A Review
منشور في 2016"…500 mV (vs SCE), together with the intensities of the Fe and FeCO3 signals from the in-situ synchrotron XRD [1]. There is a clear peak in the current transient, with the XRD results showing FeCO3 formation during the increasing portion of this transient and then a rapidly decreasing rate of FeCO3 formation as the anodic current decreases towards the end of the test, indicating the growth of a protective surface scale. …"
