Summary: This study provides a detailed insight into the correlation between superhydrophobicity, erosion-corrosion resistance, and reinforcing phase amounts of Ni-Al2O3 nanocomposite coatings electrodeposited on Cu for the first time. The results show that there is no synergy between superhydrophobicity and erosion corrosion resistance, and the nanocomposite coating with 2.9wt% Al2O3 exhibits the best erosion-corrosion resistance.

Summary: Films with micron thickness were prepared on copper through thiol-based click reaction without metal catalyst or light irradiation. The protection efficiencies of the epoxy silane and vinyl ester-silane participated click-assembly films were 99.6% and 99.4%, respectively. The film formation was driven by the strong interaction between thiol and copper, leading to the formation of new C-S bonds via thiol-ene or thiol-epoxy reaction. Molecular dynamics simulation provided theoretical support for the experimental conclusion by revealing the most stable adsorption configurations and adsorption energy of the building blocks on the copper substrate.

Summary: In this study, we fabricated superhydrophilic aluminum alloy (AA 6063) and obtained superhydrophobic samples through functionalization. However, the corrosion resistance and water contact angle of the superhydrophobic samples gradually reduced upon prolonged exposure to salt solution, indicating that the initial high contact angle cannot be used as a measure of long-term corrosion stability.

Summary: This study investigates the inhibition efficiency and mechanism of the sustainable green corrosion inhibitor sodium silicate (SS) for carbon steel in a dynamic 3 wt% NaCl environment. Electrochemical impedance spectroscopy and potentiodynamic scans were performed under variable conditions using a rotating cylinder electrode setup. Increasing the dosage of SS (<=10mM) under constant laminar flow resulted in higher inhibition efficiency (up to 99.8%), attributed to the replacement of water by silicate species and the formation of a more structured film on the steel surface. Increasing the flow rate led to maximum inhibition efficiency at an intermediate flow rate, due to faster transport of silicate and cathodic species to the steel surface and increased mechanical removal of the film.

Summary: The corrosion behavior of Al-Zn coatings on steel sheets in a polluted marine atmosphere was evaluated using weight loss tests, potentiodynamic polarization curves, electrochemical impedance spectroscopy, and acid salt spray test. The results showed that the Al-Zn coating formed a passivation film of Al2O3 with good corrosion resistance, resulting in a thick and dense layer of insoluble corrosion products. Furthermore, corrosion products such as Zn5Cl2(OH)8.H2O and NaZn4(SO4)Cl(OH)6.6H2O obstructed the diffusion of corrosive substances into the coating, thereby inhibiting further corrosion.

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.
