“…It was found that the i corr decreased and R ct increased, while the corrosion rate of carbon steel decreased. After immersion for 15 days, compared with the sterile system, the contact between the carbon steel and the corrosive ions and O 2 in the solution was prevented by the thick protective layer on the surface . The cathodic process of its electrochemical reaction was inhibited (Figure ).…”

“…After immersion for 15 days, compared with the sterile system, the contact between the carbon steel and the corrosive ions and O 2 in the solution was prevented by the thick protective layer on the surface. 53 The cathodic process of its electrochemical reaction was inhibited ( Figure 9 ). Moreover, the thick protective layer prevented microorganisms from using nutrients in solution to grow, which resulted in iron being directly used by SRB as a nutrient for growth.…”

The corrosion behavior of sulfate-reducing bacteria (SRB) on 20# carbon steel in the NaCl alkali–surfactant–polymer (ASP) flooding system was studied by scanning electron microscopy, electrochemical measurement, X-ray photoelectron spectroscopy, and laser confocal microscopy. The results showed that the presence of SRB results in a large viscosity loss of the system. SRB can use hydrolyzed polyacrylamide (HPAM) as a nutrient to grow, and the number of SRB remained at a high level after 15 days. Weight loss and electrochemical tests indicated that SRB promoted corrosion of pipeline steel. The corrosion of carbon steel in the early stage of immersion was inhibited by the biofilm formed on the surface, and the thick biofilm in the later stage of immersion caused serious pitting corrosion. The localized corrosion caused by SRB was not inhibited by HPAM and sodium petroleum sulfonate (surfactant) adsorbed on the surface.

“…Although Ti and its alloys usually exhibit excellent corrosion resistance due to the passive film on their surfaces, the presence of microorganisms may damage the passive film and cause corrosion of the Ti [ 6 , 7 , 8 , 9 ]. Among the most widely existing microorganisms in crude oil are sulphate-reducing bacteria (SRB) [ 10 , 11 ]. Under anaerobic conditions, SRB derive energy from the reoxidation–reduction reaction, which uses hydrogen produced in the bacterial biofilm to reduce sulphate to hydrogen sulphide.…”

“…Under anaerobic conditions, SRB derive energy from the reoxidation–reduction reaction, which uses hydrogen produced in the bacterial biofilm to reduce sulphate to hydrogen sulphide. Then, the pH of the local chemical environment will decrease, which will destroy the stability of passive film and enhance the corrosion sensitivity of metal [ 10 , 12 ]. Microbiologically influenced corrosion (MIC) may occur when the SRB biofilm is formed because hydrogenase from the SRB biofilm promotes a cathodic reaction, and the anodic dissolution of metal will be accelerated [ 13 , 14 , 15 , 16 ].…”

As a promising material for petroleum industrial applications, titanium (Ti) and its alloys receive wide attention due to their outstanding physicochemical properties. However, the harsh industrial environment requires an antifouling surface with a desired corrosion resistance for Ti and its alloys. In order to achieve the desired antifouling properties, micro-arc oxidation (MAO) was used to prepare a Cu-doped TiO2 coating. The microstructure of the Cu-doped TiO2 coating was investigated by TF-XRD, SEM, and other characterization techniques, and its antifouling and anticorrosion properties were also tested. The results show the effects of the incorporation of Cu (~1.73 wt.%) into TiO2 to form a Cu-doped TiO2, namely, a Ti–Cu coating. The porosity (~4.8%) and average pore size (~0.42 μm) of the Ti–Cu coating are smaller than the porosity (~5.6%) and average pore size (~0.66 μm) of Ti–blank coating. In addition, there is a significant reduction in the amount of SRB adhesion on the Ti–Cu coating compared to the Ti–blank coating under the same conditions, while there is little difference in corrosion resistance between the two coatings. There, the addition of copper helps to improve the fouling resistance of TiO2 coatings without compromising their corrosion resistance. Our work provides a practical method to improve the antifouling function of metallic Ti substrates, which could promote the application of Ti in the petroleum industry.
