Summary: In this study, the corrosion behavior and mechanism of H62 brass and T2 copper in an urban atmosphere were investigated. Copper mainly forms Cu2O and CuO as corrosion products, with the presence of a small amount of Cu2Cl(OH)3. Brass shows additional Zn-containing compounds, such as ZnCl, ZnO, and ZnS, in its corrosion product. The corrosion rate of brass decreases with time, while that of copper initially increases and then decreases after 12 months. Brass exhibits better corrosion resistance than copper in the urban atmosphere. The results of this study provide scientific data support for material selection and life prediction of equipment used in urban environments.

Summary: Due to its high ductility and formability, cartridge brass is widely used in various fields such as ammunition, plumbing, fasteners, and radiator cones. However, the brass shell used in a 130 mm shell was found to crack and suffer from dezincification during firing, leading to shell expansion and clogging. The failure analysis revealed that insufficient annealing time and dezincification were the main causes of crack initiation and propagation. The study recommended the use of dezincification-resistant alloys as starting materials and optimization of annealing time to improve the performance of brass shells.

Summary: The research explored the stress corrosion cracking behavior of 2024-T351 and 7075-T651 in solution and thin electrolyte layer (TEL) through various tests. It was found that corrosion in TEL is more severe than in solution, with different levels of SCC susceptibility in the two alloys. The degradation in TEL is primarily dominated by corrosion-induced hydrogen, while the elongation loss in solution is controlled by the synergistic effect of stress, corrosion, and hydrogen.

Summary: In H2O-saturated supercritical CO2, H2S promotes the formation of a protective FeS layer, but increasing temperature or adding O-2 can destroy the integrity of this layer and enhance corrosion significantly. The corrosion is likely controlled by gas chemical reactions instead of electrochemical reactions, and the sulfide stress cracking susceptibility of strained pipeline steels is lower than expected.

Summary: This research examined the corrosion behavior and susceptibility to stress corrosion cracking (SCC) of a high-pressure die-cast secondary AlSi9Cu3(Fe) alloy in 3.5% NaCl solution. Various testing methods revealed the presence of critical surface segregation zones, where strong corrosion attack occurred due to composition differences and peculiar morphology of noble Al2Cu phases. No SCC susceptibility was detected, but localized corrosion attack and hydrogen gas bubbling were observed at the interphases of noble phase/alpha-Al matrix.

Summary: The effect of thermal ageing at 150 oC on the corrosion behaviour of Scalmalloy (R) alloy additively manufactured by laser powder bed fusion is investigated. The results show that cyclic polarisation curves, electrochemical impedance measurements, and mechanical tests exhibit similar results before and after the thermal treatment. However, electron microscopy characterisation reveals that the application of this temperature for sufficient time causes sensitization of the alloy to intergranular corrosion processes.

Summary: The effect of bisulfite (HSO3-) on the stress corrosion cracking (SCC) behavior of 7050-T7451 aluminum alloy in the presence of Cl- in a thin electrolyte layer environment is investigated. The addition of HSO3- inhibits corrosion initiation but promotes corrosion propagation and hydrogen uptake. Quantitative calculation demonstrates that HSO3- significantly facilitates the synergistic effect among stress, corrosion, and hydrogen, causing a shift in the controlling step of SCC from corrosion-induced hydrogen to mechanical-electrochemical-hydrogen interactions. The buffer effect of HSO3- plays a dominant role in the HSO3--induced acceleration of SCC degradation.

Summary: A high-precision angular-dependent potential of the Ni-Pd system was obtained by fitting experimental data and calculations. The element segregation and thermal stability of Ni-Pd bimetallic nanoparticles were then investigated using Monte Carlo and molecular dynamics methods. The results indicate that the chemical ordering pattern of PdxNi1 - x nanoparticles is influenced by surface energy, strain energy, bond energy, and interface energy. When Pd atoms are doped into the Ni nanoparticles, they segregate on the surface, leading to improved catalytic activity and carbon deposition resistance. Increasing the doping amount of Pd atoms lowers the melting point and enhances sintering resistance.

Summary: The poor charge separation efficiency hinders the photocatalytic hydrogen production, and the establishment of heterojunctions between phase interfaces is a solution to this problem. In this study, a 2D ultrathin van der Waals (VDW) heterojunction MoC@NG@CN was synthesized to improve photocatalytic hydrogen evolution under visible light irradiation. The optimized photocatalyst MoC@NG-70@CN exhibited the highest photocatalytic hydrogen production activity, which was 13.4 times higher than that of pristine CN. Our work highlights the importance of MoC@NG for enhancing the photocatalytic performance of CN and provides insights into the construction of 2D VDW heterojunction photocatalysts.

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: 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.
