Additively manufactured super duplex stainless steel (SDSS 2507) is a promising candidate for marine hardware, but its microstructure and passive-film stability are highly sensitive to post-processing. We present an integrated framework that combines experiments, physics-based modeling, and machine learning to predict…

Developing scalable and environmentally benign anticorrosion coatings is critical for protecting steel infrastructure in chloride-rich environments. Here, a nacre-inspired multilayer epoxy coating reinforced with four MXene systems is investigated. This architecture forms a dense lamellar network that increases…

Corrosion of materials not only accounts for about 3 to 4% of economic losses in GDP in an industrial nation, but it also contributes significantly to greenhouse emissions and climate change because material production is one of the largest greenhouse emitters. According to a recent research study [1], steel production…

One hour of immersion is enough to distinguishing different performances depending on the system (Fig. 10a and b). It is noticeable the low impedance values that were observed for samples with rGO 0.1 wt% and 0.15 wt%. However, considering the behaviour observed in the free film experiments, the low impedance values…

Iron corrosion is a persistent issue across a wide range of industries, leading to both economic setbacks and safety concerns. This process is driven by electrochemical reactions that occur when the metal interacts with its surrounding environment. However, the complexity of electrochemical interfaces hinders good…

Desulfovibrio vulgaris and Desulfovibrio ferrophilus were previously proposed to have distinct iron corrosion mechanisms because D. ferrophilus corroded faster. However, the chloride concentration in the D. ferrophilus ‘marine’ medium was much higher than in the D. vulgaris ‘freshwater’ medium. D. vulgaris corrosion…

Steels, and in particular stainless steels, play a crucial role in the construction of large particle accelerators and high-energy physics experiments, of fusion reactors and their superconducting magnet structures. Such projects face severe material challenges, as they require a wide application of tightly specified…

The reductive dechlorination of carbon tetrachloride (CT) was examined in aqueous suspensions of sulfate green rust (GRSO4) amended with either Co(II), Cr(VI), Hg(II), Mn(II), Mo(VI), Ni(II), Pb(II), V(III), or Zn(II). The rate of CT reduction in the Hg(II)-amended GRSO4 suspension was ~1000 times faster than in…
