“…It is worth noting that chromium exhibits some degree of cytotoxicity towards SRB. In stainless steel, Cr has a significant effect on the attachment of SRB biofilms and elevated Cr content tends to decrease the number of attached bacteria [30].…”

“…In the context of oil and gas field production, the presence of microorganisms alongside corrosive media such as CO 2 and H 2 S often complicates the corrosion process. Chromium is a key component in the formation of protective passivation films; thus, its addition to steel can facilitate the creation of a Cr oxide film, thereby enhancing the steel's corrosion resistance [16,17]. Low-Cr content steel, with concentrations of 1 wt% Cr, 3 wt% Cr, or 5 wt% Cr, has demonstrated a certain level of corrosion resistance and economic viability compared to carbon steel and stainless steel [18].…”

Microbiologically influenced corrosion has become a predominant cause of pipeline and equipment failure in oil and gas fields. This research examines the corrosion behavior of steels with varying chromium contents in simulated shale gas formation water environments. Weight loss testing, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), Focused Ion Beam (FIB), Transmission Electron Microscopy (TEM), and X-Ray Photoelectron Spectroscopy (XPS) were employed. The findings suggest that an elevated Cr content in steel results in a gradual reduction in its uniform corrosion rate in a CO2-SRB coexistence environment. This can be primarily attributed to the significant distribution of Cr content throughout the entire product film, including both biofilm and corrosion products, thereby enhancing the product film's protectiveness. Additionally, the competitive corrosion between CO2 and SRB, as well as the influence mechanism of Cr on corrosion, were discussed.

“…Nevertheless, after being immersed in the SRB medium for 4 days, i corr decreases, probably due to biofilm formation [58]. The biofilm that forms on the metal surface effectively decreases the ionic and electronic conductivity of steel [59][60][61]. After immersion for 11 days in the SRB medium, i corr starts to increase.…”

Corrosion and wear issues of motion components exposed to water-based corrosion mediums, e.g., naval vessels and oil extraction equipment, pose challenges for the lifespan and reliability of the motion systems. In this work, epoxy-based coatings modified with polytetrafluoroethylene (PTFE) and cuprous oxide (Cu2O) nanoparticles were prepared. The anti-corrosion performance of the coatings was comparatively investigated by electrical impedance spectroscopy and Tafel tests in sterile and sulphate-reducing bacteria (SRB) mediums. Moreover, the tribological behaviors of the coatings were examined under water lubrication conditions. Our results demonstrate that the epoxy coatings lower significantly the corrosion current density icorr and the charge transfer resistance of the electrical double layer Rct of the carbon steel substrate. Interestingly, the hybrid coatings filled with both PTFE and Cu2O exhibit excellent anti-corrosion and anti-wear performance. After being immersed in the SRB medium for 18 days, the icorr of the pure EP coating and hybrid coatings are 1.10 × 10−7 Amp/cm2 and 0.3 × 10−7 Amp/cm2, and the Rct values are 1.04 × 103 Ω·cm2 and 3.87 × 103 Ω·cm2, respectively. A solid tribofilm forms on the stainless steel counterface sliding against the hybrid coating, which is surmised to be essential for the low friction coefficients and wear. The present work paves a route for formulating the dual-function coatings of anti-biocorrosion and anti-wear.
