In situ synchrotron X-ray diffraction study of scale formation during CO2 corrosion of carbon steel in sodium and magnesium chloride solutions

Applications of in situ synchrotron XRD in hydrometallurgy: Literature review and investigation of chalcopyrite dissolution

“…In this work, the versatility of this in situ technique was demonstrated by the phase transformation of lead dioxide (α-PbO 2 ) in 1 mol L −1 H 2 SO 4 solution to PbSO 4 and β-PbO 2 during cathodic and anodic polarization, respectively. The approach was followed by others aiming at a better understanding of the rates and mechanisms of corrosion of commercial materials, such as carbon steel and metallic copper (De Marco et al, 2005;Ingham et al, 2010Ingham et al, , 2012Leyssens et al, 2005).…”

Corrosion behavior of low-alloy steel with martensite/ferrite microstructure at vapor-saturated CO2 and CO2-saturated brine conditions

“…Therefore, some contrary results and interpretations have been proposed for carbon dioxide corrosion behavior of MT steel. Ko et al [22][23][24][25] have investigated carbon dioxide corrosion behavior of carbon steel and low-alloy steel by using in situ synchrotron X-ray diffraction. Their results demonstrate that the nucleation and growth of siderite and chukanovite onto the coupons surface of P/F steel and TM steel depends on the initial surface roughness and microstructure, and chromium microalloying is extremely important for FeCO 3 crystal nucleation.…”

Formation mechanism and protective property of corrosion product scale on X70 steel under supercritical CO 2 environment

“…However, as listed in Table 1, the investigations of steels immersed in SC CO 2 -saturated brine were limited. The effect of saline ions, especially Cl -, on the corrosion rate of steels has been widely investigated [51][52][53][54][55], it is generally believed that the maximum corrosion rate of carbon steel is obtained with Cl -content of about 25 g/L, similar to the content of Cl -in a 3.5wt% NaCl solution or in seawater. Moreover, the existing models have not well predicted the corrosion rate of steels at SC CO 2 conditions [39,[56][57].…”
