Summary: The crevice corrosion of X70 steel varies in different pH solutions, with pH=2 and pH=12 solutions promoting crevice corrosion while pH=6.8 solution prevents it. The increase of pH and Cl- inside crevice contribute to crevice corrosion in pH=2 solution, while the decrease of pH and increase of Cl- inside crevice lead to crevice corrosion in pH=12 solution.

Summary: This study investigated the regulatory mechanisms of autoinducer-2 (AI-2) on Q235 carbon steel corrosion caused by Desulfovibrio sp. Huiquan2017 in cultures with extremely deficient organic electron donor. It was found that AI-2 promoted bacterial chemotaxis to Fe2+ and enhanced biofilm formation, leading to increased weight loss and aggravated selective phase corrosion.

Summary: The influence of Ca2+ on the growth mechanism of CO2 corrosion products was explored through weight loss, in situ electrochemical measurements, and analysis of corrosion products. The increase in Ca2+ concentration in the solution weakened the crystallinity of the product film, FexCa(1-x)CO(3), gradually transforming it into an amorphous structure. This resulted in reduced protectiveness and an elevated corrosion rate. Higher concentrations of Ca2+ led to unstable growth of FexCa1-_xCO3. At 10000 mg L-1 Ca2+, complex FexCa1_xCO(3) structures with varying Ca content were formed. A linear relation between Ca2+ concentration in the solution and the molar fraction of Ca in the film was also proposed.

Summary: EH40 steel's corrosion behavior in seawater enriched with Methanococcus maripaludis was investigated, showing initial inhibition of corrosion followed by eventual propagation. The presence of M. maripaludis promotes both anodic and cathodic reactions of EH40 steel, while the protective corrosion products film inhibits corrosion during early immersion stages. Pitting corrosion is closely related to uneven distribution of M. maripaludis biofilm on EH40 steel surface.

Summary: This study aims to improve the corrosion resistance of carbon steel by depositing phosphate and paint layers on its surface, which showed higher polarization resistance in saltwater. Additionally, the corrosion rate was observed to decrease with longer immersion time. SEM and EDS analysis revealed the formation of iron oxides or hydroxy-oxides on the sample's surface after immersion, indicating that all types of deposited layers enhance the corrosion resistance of C45 steel.

Summary: D-phenylalanine has been shown to prevent localized corrosion on Q235 carbon steel by inhibiting biofilm formation and altering biofilm structure when lactate is the main electron donor. When lactate and yeast extract are removed, D-Phe significantly reduces overall corrosion loss, likely due to its involvement in the Stickland reaction involving L-cysteine and bacteria-transformed L-phenylalanine.

Summary: In this study, a new composite polymer coating N-methylpyrrole-Triton-X100/N, N,N-diethylaniline (NMPY-TRX100/NNDEA) was synthesized on carbon steel type OL 37 electrode for corrosion protection using an electrodeposition method. The surfactant Triton-X100 played a significant role in improving the corrosion protection performance of the composite by impeding the penetration of corrosive ions. The PNMPY-TRX100/PNNDEA coatings exhibited good anticorrosion protection of OL 37 in corrosive solutions, with corrosion rates around nine times lower than uncoated electrodes and a corrosion protection yield of over 90%.

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.

Summary: The relationship between configurational entropy and lattice distortion in novel rare earth monosilicates was investigated, and the effect of configurational entropy on their properties was studied. The results showed that lattice distortion increased with the increase of configurational entropy, but a highly symmetrical crystal structure was formed when the configurational entropy was large enough, inhibiting the lattice distortion.
