“…In fact, despite the various developments, underground structural failures continue to occur [ 1 , 2 , 3 ]. Here, the corrosion of metallic infrastructures in underground soil is a major issue that presents numerous safety and economic concerns [ 4 , 5 , 6 , 7 , 8 ]. In short, pipelines can be damaged by corrosion, which can lead to the failure of the structures within a soil environment.…”

Various studies have been conducted to better understand the long-term corrosion mechanism for steels in a soil environment. Here, electrochemical acceleration methods present the most efficient way to simulate long-term corrosion. Among the various methods, galvanostatic testing allows for accelerating the surface corrosion reactions through controlling the impressed anodic current density. However, a large deviation from the equilibrium state can induce different corrosion mechanisms to those in actual service. Therefore, applying a suitable anodic current density is important for shortening the test times and maintaining the stable dissolution of steel. In this paper, to calibrate the anodic current density, galvanostatic tests were performed at four different levels of anodic current density and time to accelerate a one-year corrosion reaction of pipeline steel. To validate the appropriate anodic current density, analysis of the potential vs. time curves, thermodynamic analysis, and analysis of the specimen’s cross-sections and products were conducted using a validation algorithm. The results indicated that 0.96 mA/cm2 was the optimal impressed anodic current density in terms of a suitable polarized potential, uniform corrosion, and a valid corrosion product among the evaluated conditions.

“…Two common approaches are employed to study soil corrosion: conducting research in the field [12,15] or performing experiments under laboratory conditions [16,17]. Simulated soil solution has been used to study the influence of the physicochemical properties of soil on the corrosion behavior of buried steel [18][19][20]. In general, a simulated soil solution contains Cl⁻ , SO₄ ²⁻ , and HCO₃ ⁻ [21].…”

Solid agar based gels have been investigated as an electrolyte system for the electrochemical study of soil corrosion, specifically microbiologically influenced corrosion (MIC) in soil. Traditional techniques for studying corrosion in soil include solutions and soil samples; however these systems do not reliably simulate the physico‐chemical properties of soil. Soils are complex environments with three phases critical to corrosion (solid‐soil, liquid‐water and gas‐oxygen). Therefore there is a need for a system which replicates and considers this complex environment and its effects on corrosion processes, while reducing inconsistencies and variations associated with moisture and oxygen content in soil. Open circuit potential (OCP) and potentiodynamic scans (PDS) were conducted on carbon steel exposed to solid agar electrolyte with varying oxygen concentrations. Results were analysed using Tafel extrapolation, consistency in anodic‐cathodic trends and optical microscopy of the exposed regions. For the conditions tested, a cathodic shift was seen with the observed corrosion potentials being notably lower than the measured OCPs. Consistency in the anodic‐cathodic trends of the PDS was observed with minimal oxygen conditions. Overall, an agar based gel system has potential as an electrolyte for soil based MIC studies, especially as an analogue for moist clay soils.
