“…Polarization resistance ( R p ) from LPR scans in Figure 4B describes the transient corrosion kinetics during the 14-day incubation. R p is inversely proportional to corrosion rate ( Cai et al, 2022 ). Figure 4B shows a large drop of R p in the first 3 days, suggesting that as biofilm established on the metal surface, corrosion rate increased.…”

Apart from pinhole leaks, MIC (microbiologically influenced corrosion) can also cause catastrophic failures such as pipe ruptures and support beam collapses due to mechanical property degradation or stress corrosion cracking. In this work, X80 pipeline steel dogbone coupons and square coupons were immersed in 150 ml broths containing Desulfovibrio vulgaris, a common corrosive sulfate reducing bacterium (SRB), for up to 14 days. The headspace volumes in the anaerobic bottles were increased from 150 ml to 200 ml and 300 ml to increase MIC severity. After 14 days of SRB incubation in ATCC 1249 culture medium with X80 coupons at 37°C, the sessile cell counts were 6.5 × 107 cells cm−2 for 150 ml, 2.3 × 108 cells cm−2 for 200 ml and 1.4 × 109 cells cm−2 for 300 ml headspace volumes, respectively owing to reduced H2S cytotoxicity in the broth with a larger headspace because it allowed more biogenic H2S to escape from the broth. Weight losses were 1.7 mg cm−2, 1.9 mg cm−2 and 2.3 mg cm−2 for 150 ml, 200 ml and 300 ml headspace volumes, respectively. The corresponding pit depths were 2.6 μm, 4.2 μm and 6.2 μm for 150 ml, 200 ml and 300 ml headspace volumes, respectively. Electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR) and potentiodynamic polarization results corroborated the increasing weight loss and pitting data trends as a result of increased headspace. Tensile testing of dogbone coupons after the 14-day SRB immersion test indicated that more severe MIC pitting led to a higher ultimate strain loss by up to 23% (300 ml headspace) compared to the abiotic control, while the ultimate strength losses for all headspace volumes were quite small (3% and lower).

“…The results indicate that bacterial attachment decreased as carbon content increased, whereas the corrosion rates showed a linear increase with carbon content. In contrast, Cai et al [71] studied corrosion behaviours of Q235, X65, X70, and X80 steels in a soil solution with a mixed SRB culture and found no direct relation between MIC and carbon content across different steel grades. They found that the MIC rate followed the order of X70 > Q235 > X65 > X80, whereas the carbon content increased in the order of Q235 > X70/X65 > X80.…”

Microbially influenced corrosion (MIC) is a potentially critical degradation mechanism for a wide range of materials exposed to environments that contain relevant microorganisms. The likelihood and rate of MIC are affected by microbiological, chemical, and metallurgical factors; hence, the understanding of the mechanisms involved, verification of the presence of MIC, and the development of mitigation methods require a multidisciplinary approach. Much of the recent focus in MIC research has been on the microbiological and chemical aspects, with less attention given to metallurgical attributes. Here, we address this knowledge gap by providing a critical synthesis of the literature on the metallurgical aspects of MIC of carbon steel, a material frequently associated with MIC failures and widely used in construction and infrastructure globally. The article begins by introducing the process of MIC, then progresses to explore the complexities of various metallurgical factors relevant to MIC in carbon steel. These factors include chemical composition, grain size, grain boundaries, microstructural phases, inclusions, and welds, highlighting their potential influence on MIC processes. This review systematically presents key discoveries, trends, and the limitations of prior research, offering some novel insights into the impact of metallurgical factors on MIC, particularly for the benefit of those already familiar with other aspects of MIC. The article concludes with recommendations for documenting metallurgical data in MIC research. An appreciation of relevant metallurgical attributes is essential for a critical assessment of a material’s vulnerability to MIC to advance research practices and to broaden the collective knowledge in this rapidly evolving area of study.

“…[32,[35][36][37] For laboratory research, electrochemical techniques are often applied in well-controlled environments to understand the reactions within a corrosion system while comparing different environmental conditions, often using aqueous solutions that incorporate the chemical composition of soil as the test medium. [38][39][40][41] However, on top of the role of both oxygen and chloride content on corrosion and MIC in soil, the influences of soil particle size, pore spacing, and structure on aeration and corrosion cells, the TPB zones at the soil and pipe interface as well as bacterial attachment to pipe surfaces are all important distinctions that separate corrosion behavior in soil samples and simulated soil solution. [8][9][10][11]42] In fact, corrosion rates in simulated soil solution and soil samples differ significantly according to research in which empirical data of corrosion rates in simulated soil solution, soil acidity, and corrosion time were used to predict corrosion rates in soil.…”

Aqueous electrolyte traditionally used for electrochemical characterization of soil‐related corrosion in laboratories fails to represent the soil physical features, such as pore structure, soil heterogeneity, soil compaction, and saturation levels, in the diffusion‐controlled corrosion process. This article introduces a semi‐solid agar system to reproduce the physical structure of soil for corrosion study. For feasibility validation of the agar system, direct comparison regarding electrochemical activity, diffusion characteristics, and corrosion mechanisms has been performed on pipeline steel in aqueous sodium chloride (NaCl) solution (5 g L−1), 5 g L−1 NaCl‐containing agar, and 5 g L−1 NaCl in sand, respectively. The results indicates that oxygen diffusion in agar and sand media is similar, which significantly weakens the cathodic activity of steel specimens, but leads to distinct corrosion characteristics from those identified in aqueous NaCl solution counterparts. The high diffusion rate of chloride ions in aqueous solution also accelerates corrosion of pipeline steel in NaCl solution through extensive attack at defect sites, but the limited chloride ion movement and the diminished driving force for anodic corrosion activity reduce such attack in their agar and sand equivalents. The solid nature of agar outperforms aqueous electrolytes as soil replicate to explore soil‐related corrosion responses at laboratory scale.
