Summary: The corrosion behavior and corrosion rate of friction stir welded AZ31B magnesium alloy and 6N01 aluminum alloy dissimilar joints were studied using real-time imaging, potentiodynamic polarization, EIS, and hydrogen evolution tests. The corrosion rate was found to increase in the order of Al base metal < Mg base metal < stirred zone. The galvanic coupling of the Mg phase to other phases enhanced the corrosion of both base metals, and intense corrosion at BM-AZ31B elevated the interfacial pH due to water reduction on the cathodic particles of BM-6N01.

Summary: The study found that the critical point where the corrosion rate changes is at 12% strain level, before which the corrosion rate first increases and then decreases. The antagonistic effect of basal structure and dislocation aggregation plays a crucial role in corrosion resistance. With an increase in strain, the number of twins increases, causing a continuous decrease in corrosion resistance.

Summary: The study investigated the effect of heat treatment on the microstructure and corrosion behavior of a high Mo containing titanium alloy. Different microstructures were observed depending on the heating temperature and cooling conditions. Heat-treated samples showed improved corrosion resistance, attributed to the presence of stable TiO2 film on the corroded surfaces. Samples treated at 950 degrees Celsius exhibited the best corrosion resistance overall.

Summary: The addition of organic or inorganic corrosion inhibitors can reduce the corrosion rate of steel bars in chloride solution. Compared to single component inhibitors, the multi-component inhibitor significantly restrains the corrosion of steel bars in simulated pore solution. The adsorption film formed by the multi-component corrosion inhibitor on the surface of steel bars can significantly reinforce the passive film through physical or chemical processes.

Summary: Cu-based immiscible coatings reinforced with 10 wt% Fe-based amorphous powder were produced by laser melting deposition. The microstructure and corrosion behavior were investigated. The results showed that the interface of the coating and substrate changed from poor bonding to good bonding and crack debonding with increasing laser energy density. The corrosion characteristics also transformed from crevice corrosion to enhanced protection of passive films and reduced protection of passive films. The immiscible coating deposited with a laser energy density of 31.25 J/mm2 exhibited the highest corrosion resistance.

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.
