Erosion resistance of CO2 corrosion scales formed on API P110 carbon steel

Review of Studies on Corrosion of Steel by CO2, Focussed on the Behaviour of API Steel in Geological CO2 Storage Environment

“…Similarly, Guan [40] -at 90 °C and 4 MPa -obtained a corrosion rate around 0.8261 mm/yr; at 110 °C with the same pressure, the rate was 0.2489 mm/yr. On the other hand, if the pressure was varied (0.1, 2, 4 and 6 MPa), maintaining the same temperature (100 °C) for 168 h, the results were 0.64, 0.76, 0.91 and 0.83 mm/yr, respectively [41].…”

Impact of corrosion on sliding wear properties of low-alloyed carbon steel

“…Despite the fact that this synergistic process has been highlighted by many authors [8,9], the simultaneous combination of mechanical wear and corrosion is often neglected and most of the experimental data available on the tribocorrosion of steels under CO 2 atmosphere relies on evaluating the erosion resistance of CO 2 corrosion layers [8] or in sequential corrosion and wear experiments [9]. The combination of wear and corrosion on a tribometer test is seldom reported, and when done, other relevant environmental conditions such as high pressure and temperature, are not applied [13].…”

“…Dense and good adhered CO 2 corrosion layers provide a good protection by acting as physical barriers and suppressing mass diffusion [4][5][6][7]. However, this layer can be damaged or fully removed by several physical processes, such as mechanical wear, elastoplastic deformation, impingement of solid particles, and fluid shear stress [8][9][10][11][12]. Therefore, when corrosion occurs simultaneously with mechanical wear, the synergy between both degradation mechanisms does not allow simplifying the whole process as the individual contributions of corrosion and wear.…”

Effects of tensile stress on electrochemical characteristics and structural morphology of P110SS steels in carbon dioxide-saturated solution

“…A large number of researchers [6][7][8] have concluded that the surfaces of casing steels form FeCO 3 corrosionproduct films because of the existence of wet CO 2 in high-temperature, high-pressure environments. Corrosion-product films have a decisive influence on the corrosion behavior of casing steels, regardless of whether further corrosion reactions occur.…”
