“…The general View (Figure 10(a-1)) reveals that in addition to scratches originating from mechanical polishing, an extra layer could be noticed even though the detailed morphology fails to be resolved at this magnification. Figure 10(a-2) displays the framed area in Figure 10(a-1) at an increased magnification, which reveals the presence of rod-shaped features with typical dimensions ranging from several micrometres to over 10 µm, supposedly SRB bacteria [11,13,16,41]. The framed area of Figure 10(a-2) is further magnified in Figure 10(a-3), displaying the fusion of these bacteria, which indicates the initial formation of biofilm after only 14 days' immersion.…”

The limited antifouling capability of Ti-based components could jeopardize their applications in petroleum engineering. In this work, a Cu-enriched TiO2 coating has been fabricated using an ultrasound-auxiliary micro-arc oxidation (UMAO) method. The Cu enrichment of TiO2 affects its morphology, phase component and chemical configuration, leading to the slightly enhanced corrosion resistance of the Cu-enriched TiO2 coating relative to that free of Cu. Finally, the antifouling capability against sulphate-reducing bacteria (SRB) is significantly improved by preventing the formation of biofilm after the Cu enrichment of TiO2, which potentially widens its application in petroleum engineering.

This study reviews the metal corrosion problem regarding the carbon capture, utilization, and storage (CCUS) technology and aims to deepen the understanding and research on this problem and thus deal with the severe material corrosion failures in the capture, transportation, utilization, and storage systems. Based on the novel corrosion environments, the uniqueness of corrosion behaviors, limited cognition, and relative lack of protective measures in CCUS technology systems, this study analyzes the possible types of metal corrosion and its major influencing factors, explores the challenges it brings, and draws the following conclusions. For the CO 2 organic amine capture system, the degradation mechanism of absorbents and the impact of degradation products on the corrosion process are complex, and some degradation products have a inhibitory effect on metal corrosion. The internal corrosion issue of dense-phase CO 2 transmission pipelines cannot be ignored, and controlling the moisture content is the key to controlling this corrosion problem. The risk of corrosion failures leading to CO 2 leakage is high in the wellbore tubing of CO 2 enhanced oil recovery utilization and storage systems under the long-term coupled effects of ultra-high CO 2 partial pressure, carbon source impurities, high mineralized formation water, microorganisms, and stress. Finally, the research that needs to be conducted urgently in the future is prospected, including the corrosion impact of different carbon source impurities on each subsystem, the material degradation law in the wellbore area under long-term storage conditions, and corrosion protection technologies of CCUS systems.

“…Generally, low-alloy structural steels have been widely used in the fields of bridges, containers, and infrastructures. However, corrosion occurs during service, [1][2][3][4][5] such as atmospheric corrosion, and microbiologicalinduced corrosion, leading to considerable economic losses and heavy casualties. [6][7][8][9] The corrosion issue seriously restricts the development and application of low-alloy steel.…”

The corrosion behaviors of Sb‐free and Sb‐added low‐alloy structural steels were comparatively studied in a real tropical marine atmosphere. And the role of Sb addition on corrosion resistance was clarified by electrochemical measurement and rust analysis. The results showed that the addition of 0.05% Sb increased the polarization resistance, reduced the cathodic current density, and slowed down the oxygen reduction process. Meanwhile, Sb addition optimized the physical structure, promoted the transformation of phase, and improved the protection of the rust. More importantly, 0.05% Sb addition inhibited the local acidification at the bottom of the pits, thus slowing down the local corrosion process at the rust/matrix interface. Accordingly, the corrosion resistance of the Sb‐added low‐alloy steel was enhanced, causing a lower corrosion rate than that of Sb‐free steel in a tropical marine atmosphere.
