Summary: This study aims to improve the cavitation-erosion (CE) corrosion resistance of Ni-Al bronze propeller alloy by preparing a novel Cu-based medium-entropy alloy coating. The coating exhibited better anti-CE performance compared to the Ni-Al bronze alloy, with the main CE damage mechanism being corrosion and fatigue damage caused by the NiTi-rich precipitates in the coating.

Summary: The synergistic effect of erosion and hydrogen on the passive film of 2205 duplex stainless steel was studied in a loop system coupled with a hydrogen-charging cell. It was found that the combination of erosion and hydrogen could dramatically change the passive film component, decrease the protective performance, and increase the susceptibility of pitting corrosion of 2205 stainless steel in Cl-containing environment.

Summary: Tensile stress and erosion can independently promote general corrosion of pipeline steel. The combination of tensile stress and erosion can have a synergistic effect on general corrosion by reducing the compactness of corrosion products layer, accelerating the mass transfer process, and improving the reaction activity of the steel. Erosion suppresses localized corrosion, while tensile stress enhances it.

Summary: The cavitation erosion behaviors of two aluminum bronzes after pre-corrosion in 3.5% NaCl solution were studied. Mechanical impact was found to be the dominant factor causing the cavitation erosion damage of the pre-corroded samples. Pre-corrosion increased the contribution of pure erosion to the cavitation erosion-corrosion damage, leading to increased surface roughness and weakened mechanical properties. This resulted in significant material loss and the formation of large and deep cavities. The inferior mechanical property of one of the aluminum bronzes greatly contributed to its severe cavitation erosion damage. Pre-corrosion had a greater influence on the cavitation erosion behavior of the other aluminum bronze due to the deterioration of its cavitation resistance caused by corrosion damage.

Summary: The influence of carbon content on the microstructure, magnetic and mechanical properties, as well as corrosion behavior of WC-15Co-0.95Cr cemented carbide was systematically investigated. The results show that increasing carbon content promotes WC grain growth, but also leads to the precipitation of (Cr, W)Cx phase at the interface. The coercive force and Vickers hardness decrease with increasing carbon content, while the transverse rupture strength initially increases and then decreases. Higher carbon content cemented carbide exhibits poor corrosion resistance due to the precipitation of Cr-rich phase, resulting in the lack of Cr elements in the Co binder phase.

Summary: This study investigated the effects of Cr-optimization on the corrosion and erosion-corrosion behaviors of Hadfield steel with 1.1 wt% C-13 wt% Mn in a neutral aqueous environment. The results showed that adding Cr can enhance the corrosion and erosion-corrosion resistance, but only at the optimized Cr content of approximately 2 wt%. The newly designed Hadfield steel has favorable combination of long-term environmental stability in harsh corrosive and erosive environments, high-strength, hardness, ductility, and commercial availability, making it a promising alternative in various industrial applications.

Summary: This study examines the effect of the chemical composition of filler metals on the corrosion resistance of welded joints using GTAW process. The redistribution of chemical elements during welding operation creates variations in microscopic structure, with distinct microstructural zones identified. Results show that base metal acts as the anodic region in the welded joint, while fusion zones act as the cathodic part protected from corrosion. Corrosion tests revealed that 316L/ER308LN welded joint has better resistance to pitting corrosion, though it is less resistant to corrosion by dissolution compared to 316L/ER316LN welded joint.

Summary: This study investigates the bond properties between steel bars and concrete under the coupling of chloride ion erosion and repeated load. The results show that the bond strength decreases with an increase in the level of repeated load alone. Additionally, the bond strength under the coupling of repeated load and chloride ion erosion is lower than that under repeated load alone or chloride ion erosion alone. The bond strength gradually decreases when the corrosion ratio exceeds 1.5%. Moreover, the slip between steel bars and concrete decreases with an increase in the level of repeated load under the coupling of chloride ion erosion and repeated load when splitting failure occurs. Based on the test results, a bond strength-slip constitutive relationship is proposed.

Summary: This study investigates the influence of He-V complexes on H behaviors on different W surfaces using DFT calculations. The results show that H dissolution is most difficult but H trapping is easiest on the W (110) surface, while the opposite is true on the W (111) surface. Moreover, the presence of He-V complexes increases the difficulty of H diffusion from bulk to surface and desorption.

Summary: The characteristics of magnetron sputtered Cr coatings vary with different temperature, bias voltage, and pressure. Coatings with random orientation, good crystallinity, and small grain size exhibit favorable oxidation behavior, while coatings with strong (200) texture, poor crystallinity, and large grains have many intrinsic defects that are detrimental to the protection property of the Cr coatings.

Summary: This paper investigates the oxidation and shape evolution of matrix graphite in high temperature gas-cooled reactors during air-ingress accidents. A reaction kinetics model is established and computational fluid dynamics with a dynamic mesh method is used to simulate the oxidation process. The results show that the geometric shape of graphite changes significantly with increasing flow rate, and the graphite pebbles tend to form a structure with a narrow front and wide tail.

Summary: This study proposes a probabilistic and diffusion-based model to describe the co-deposition of multiple hydrogen isotopes with slowly grown metal layers. The model calculates the relative concentrations of different hydrogen isotopes in the co-deposited metal layers. It is found that if hydrogen isotopes have different detrapping energies, only the isotope with the highest detrapping energy shows a monotonic decrease in concentration with deposition temperature. Furthermore, the study evaluates the uncertainty of tritium concentration in the co-deposited layer based on the uncertainty in detrapping energy of tritium and deuterium, predicting a >10% tritium concentration uncertainty for a 0.01 eV difference.
