Summary: This study investigated the microbiologically influenced corrosion of metals exposed to marine tidal zone, specifically the corrosion of EH40 steel affected by Halomonas titanicae under alternate and full immersion. The transition from full immersion to alternate pattern was found to accelerate corrosion in abiotic media, but enhanced the corrosion inhibition efficiency of H. titanicae towards steel. These differences were attributed to thin electrolyte layers, increased number of sessile cells, and their possibly enhanced aerobic respiration activity during alternate immersion.

Summary: In this investigation, multi-modal characterization was used to evaluate the oxidation of Stainless Steel 304 under laboratory air and 100% steam (1200 degrees C, 2 h). Air oxidation resulted in Fe(NiMn)O4, Fe3O4, Fe(3,0CrxO4, and Cr2O3. Steam oxidation produced a dual layer structure, with a porous outer layer enriched in Fe2O3 and a sub-surface matrix of Fe3O4/Fe(3,0CrxO4 with SiO2/Fe(3_ x)SixO4. Based on these findings, an oxidation mechanism was proposed. The arrangement of oxidation products in air aligned with anticipated diffusion behavior, except for Cr2O3. However, the arrangement in steam deviated due to intergranular interactions with H2O, resulting in the formation of the sub-surface matrix.

Summary: Understanding the oxidation process of Inconel 600 (A600) in different environments is important for the development of accident tolerant nuclear fuel rod claddings. This study combines synchrotron-based diffraction, Raman spectroscopy, and nano-scale electron microscopy techniques to investigate the oxidation of A600 in steam and air environments. It was found that a Cr2O3-enriched surface layer forms in steam, while a mixed phase oxide layer containing NiFe2O4, Cr2O3, Fe3O4, and Fe((3-x))CrxO(4) forms in air.

Summary: The atmospheric corrosion performance of S235 carbon steel exposed to the tropical/marine aerosol pollutants in Port Louis, Mauritius was evaluated. The study revealed significant corrosion concerns due to the distinct microclimate of Port Louis, situated on the northwest coast. The presence of sulphur dioxide emissions from heavy oil-fired power stations further complicated corrosion prediction. The analysis showed that the corrosion progression behaviors were influenced by environmental and geographical variables, with the formation of porous surface layers leading to increased metal dissolution.

Summary: The effect of sulfate reducing bacteria (SRB) on galvanic corrosion between 2205 SS and X52 carbon steel in enriched artificial seawater was comprehensively investigated. This study is significant for understanding microbiologically influenced corrosion of bimetallic composite pipelines. Electrochemical tests revealed that galvanic effect was higher in the SRB-containing medium compared to the sterile medium. The coupling also accelerated the corrosion of 2205 SS, resulting in a 13-fold increase in weight loss.

Summary: The study shows that lean duplex stainless steels can be used in aerated wet environments with moderate H2S and chloride contamination (<10 ppm and <200 ppm). However, for higher levels of contamination (e.g., around 100 ppm H2S and around 1000 ppm chloride), duplex S32205 is the preferable choice.

Summary: High porosity Co-Al-Fe intermetallics with 3D-microstructures were successfully synthesized in one step via a thermal explosion reaction. The link between pore structure and permeability was investigated using 3D-XRM technology. The corrosion resistance of the samples with different Fe contents was studied at 900 degrees C under an oxygen/sulphur atmosphere for up to 120 h. The results showed that the samples maintained stable pore structure and intact internal matrices, attributed to the formation of a thin protective layer on the surface. In addition, inward diffusion of S resulted in the formation of FeS nodules.

Summary: In this study, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers using an in situ intercalation technique. The corrosion inhibition effect of LA was evaluated, and it was found that LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization. The inhibition of the electrochemical anodic process on the surface of mild steel was the main reason for the high corrosion inhibition efficiency of LA-GO2. The properties of the surface film on the corroded steel were also characterized in detail to understand the corrosion inhibition mechanism of LA-GO2.

Summary: The oxidation behavior of FeCrNi medium entropy alloy was investigated through experimental observations and density functional theory (DFT) calculations. The study found that at 900 degrees C, the alloy forms a desirable and continuous oxide layer, while at 1000 degrees C, the oxide layer becomes discontinuous with penetration of oxide. These observations highlight the significant role of phase structure in promoting the formation of protective oxide scales and influencing oxidation resistance.

Summary: This study presents a new approach to studying the mechanism of filiform corrosion in organic coated steel using the scanning vibrating electrode technique (SVET) and micropotentiometry (potentiometric SECM). The electrochemical activity under the coating was evaluated by mapping the ionic current densities coming from artificial defects made in specific locations of the filament. Antimony tips were also used to investigate the pH changes associated with different corrosion reactions at the metal-paint interface. Local pH levels along the filament in the anodic and cathodic regions were determined.

Summary: This work explores the correlation between electrolyte transport properties and the variation of pigment volume concentration (PVC) in organic coatings. An odd random phase electrochemical impedance spectroscopy (ORP-EIS) approach is used to analyze the diffusion of ions independent from water uptake. The results show that a higher PVC leads to a more homogeneous coating structure, resulting in faster diffusion of ions and enhanced water uptake.
