Summary: In this study, an essential oil extracted from Dysphania Ambrosioides leaves was tested as an environmentally friendly corrosion inhibitor for mild steel in 1 M HCl medium. The results showed that the extract achieved a corrosion inhibition efficiency of 84% at a concentration of 1.5 g/l. Surface analysis revealed a smoother surface with reduced roughness in the presence of the inhibitor. Theoretical investigations provided insights into the adsorption sites of the molecules from the extract on the steel surface.

Summary: This study investigates the factors influencing erosion-corrosion in oilfield gathering pipelines steel using a home-made testing pipe flow loop. The results show that steel is corroded in oil-water flow, with the corrosion rate increasing with flow velocity and the addition of solid particles intensifying localized corrosion. In an erosion-corrosion test with 2 wt% quartz sand at a velocity of 2 m/s, pure corrosion and pure erosion accounted for 47.50% and 70.83% of the damage, respectively. The erosion-enhanced corrosion contributed to 16.67% of the total weight loss, while corrosion inhibiting erosion damage accounted for 35.00%, indicating negative synergistic effects in the oil-water-sand multiphase flow conditions.

Summary: This study developed a novel bio-based waterborne epoxy coating with superior water repellency and anti-corrosion performance by embedding functionalized polydimethylsiloxane. The coating containing 5% functionalized polydimethylsiloxane showed optimum anticorrosive performance, attributed to the water-repellent property of the enriched polydimethylsiloxane and the passivation protection of benzotriazole.

Summary: Alloy films with excellent corrosion resistance were fabricated by depositing an Mg film on Al-Si coated steel sheets and applying heat treatment. The Mg in the film was widely distributed in a dissolved state on the AI phase and continuously involved in the corrosion product formation reaction, leading to the excellent barrier effect against corrosion factors. The corrosion resistance evaluation results were explained by analyzing the properties of the alloy film and the mechanism of forming corrosion products.

Summary: Magnesium ferrite nanorods and magnesium ferrite/polythiophene (MgFe2O4/PTh) composites were fabricated using sol-gel and in-situ emulsion polymerization approaches to investigate electromagnetic interference (EMI) shielding activity in the X-band region. The synergistic effect of magnesium ferrite nanorods and conducting PTh in the composites led to high shielding effectiveness, attributed to the high dielectric and magnetic loss, making them potentially useful as lightweight, high-performance EMI shielding materials.
