Based on hydrogen embrittlement-resistant surface design principles, this study investigates the microstructure and effectiveness of passivation films in blocking hydrogen. Passivation films, prepared by electrochemical methods, consist of outer FeOOH layer and inner layers of Cr2O3 and Fe2O3. The FeOOH layer, with a hydrogen adsorption capacity of −3.555 eV and a diffusion barrier of 3.766 eV, effectively prevents hydrogen penetration. The Cr2O3 and Fe2O3 layers enhance bonding between the films and the substrate as transitional layers. This synergistic structure enhances hydrogen-blocking capabilities, resulting in a 59.92 % reduction in hydrogen embrittlement sensitivity index and a 41.27 % decrease in brittle zone depth.

Recently, there has been a notable rise in the use of Hydroxyapatite (HA) coatings in medical implants, especially those composed of magnesium alloys. This study involves immersing Mg alloys in a HA and MoS2 solution for varying durations. Results indicated that HA+MoS2 coatings have greater polarization resistance than HA coating, with the 120-minute MoS2-modified coating achieving maximum corrosion resistance (30163 ohm.cm²) in a 3.5 wt% NaCl solution. Characterization techniques confirmed the successful integration of HA and MoS2, while the coatings also exhibited strong antibacterial activity. Additionally after seven days of submerging in SBF, the HA+MoS2(120 min) coating demonstrated the highest bio-corrosion resistance, measuring around 10848 ohm.cm2.

Solar salt is currently used in concentrated solar power plants with thermal energy storage. Thermal decomposition of nitrates increases the concentration of oxidizing agents and melt basicity, leading to accelerated corrosion of containment materials. This is further complicated by the impurities in industrial-grade salts. In this study, the corrosion behavior of X20CrMoV12-1, Alloy 800 H, and Haynes-230 is investigated at 600°C in different solar salt mixtures with varying impurity contents. Corrosion mechanisms, including aspects of salt decomposition, impurities, and Cr-dissolution, are discussed in detail. It is proposed that the reactants for oxidation, fluxing, and nitridation are generated from either nitrate or nitrite anions at the alloy/scale interface.

Aiming at forming a stable ablation layer for hafnium-based ultrahigh-temperature ceramics under ablation environment, in this work, the Ta-based ceramic was introduced into the Hf-based ceramic, and the effect of Hf/Ta molar ratios on the ablation response behavior and mechanism of (Hf, Ta)B2-(Hf, Ta)C-SiC ceramics was investigated. It was found that the introduction of Ta could form a continuous and dense ablation layer. When Hf/Ta= 0.9:0.1, the ceramic composite presented excellent ablation resistance, and the linear ablation rate was −0.083 μm/s, which was only 5.85 % of that of Hf-based ceramics (HfB2-HfC-SiC). The excellent ablation resistance attributed to that the ablation products (Ta2O5 and Hf6Ta2O17) could strongly bonded to the substrate, which was conducive to enhance the stability of the ablation layer.

The effect of surface finishing on the oxidation of Fe-25Ni-20Cr-4Al-based alloy at 1000 °C in an Ar + 4 % H2 + (0.15 %–0.25 %) H2O atmosphere was studied. A multi-layered oxide film formed on the polished samples, while a single-layer Al-rich oxide developed on the ground samples. The low oxidation rate of the ground samples was controlled by Al2O3, while the oxidation rate of the polished samples was influenced by both the interstitial transport mechanism of Cr and the presence of a SiO2 layer. The synergistic effects of surface roughness and oxygen pressure on the early-stage oxidation behavior of alumina-forming austenitic alloys were further explored.

The tribocorrosion behavior of 7075-T651 aluminum alloy in chloride environment with different pH is investigated. In acidic and alkaline environments, the attack of Cl- and OH- results in the larger wear volume as compared to the neutral environment. The friction coefficient decreases with an increase of load, showing the highest value in alkaline solution. The synergistic effect of corrosion and wear is promoted in alkaline solution, while it is inhibited in the acidic and neutral solutions. At open circuit potential and the anodic potential, the wear mechanisms in acidic and alkaline solutions are corrosion fatigue and adhesive wear.

A single-phase (Ni,Pt)Al coating that had been oxidized at 1100 °C for 300 h was successively removed by a soft chemical stripping method, which was then refurbished by a fresh (Ni,Pt)Al coating. Corrosion behavior of the refurbished (Ni,Pt)Al coating was studied in Na2SO4/NaCl (75:25, wt./wt.) salt mixture at 900 °C. The results revealed that the refurbished (Ni,Pt)Al coating presented similar corrosion tendency compared to the virgin coating, but the TCP phase of the former was more susceptible to precipitate and form a thicker substrate diffusion zone. The corrosion mechanism and interdiffusion behavior of the refurbished (Ni,Pt)Al coating were discussed systematically.

This study investigated the influence of tempering temperature on the microstructural evolution and stress corrosion cracking (SCC) behaviors of a newly developed high-strength mining round-link chain steel. As the tempering temperature increased, the dislocation density progressively decreased, while the amount of (V, Mo)C precipitates significantly increased. After tempering at 625 °C, a substantial number of nanoscale (V, Mo)C precipitates with a certain concentration of carbon vacancies were uniformly distributed. Compared to present commercial high-strength round-link chain steels, the newly developed round-link chain steel demonstrated superior SCC resistance at similar yield strength level. Based on the influence of nano-scale precipitates and dislocation density on hydrogen diffusion characteristics, this study further elucidated the potential mechanisms underlying hydrogen-induced stress corrosion cracking in high-strength round-link chain steel.

The effect of Li content (0.5 wt%, 1.0 wt%, 1.5 wt% and 2.0 wt%) on corrosion resistance of Al-Li alloy was studied in 3.5 wt% NaCl. The corrosion resistance is affected by changes in the characteristics of the corrosion product layer caused by variations in Li content. The alloy with 1.5 wt% Li exhibited the best corrosion resistance, which is attributed to Li2CO3 generated on its surface. Li2CO3 layer acted as a barrier to corrosive Cl- and O2. The wide bandgap of Li2CO3 hindered the transfer of electrons, increasing the resistance of cathodic reaction and retarding further corrosion.

In this study, we developed two moment tensor potentials for Ce-Ti and Ce-Ta systems. After that, molecular dynamics simulations were conducted to explore the solid-liquid interfaces and the wetting processes. Ti surfaces exhibit interfacial premelting, while Ta surfaces show excellent resistance to liquid Ce corrosion. Ce atoms form ordered layers analogous to that of the Ta surfaces. Moreover, intensive interfacial diffusion enables liquid Ce to fully wet both Ti surfaces, however, anisotropic wetting behavior is observed on Ta surfaces. These potentials pave the way for the further studies on the corrosion behavior of liquid Ce.
