Summary: The present study investigates the passivation characteristic and corrosion resistance of Al20Cr5Fe50Mn20Ti5 and Al7Cr23.26Fe23.26Co23.26Ni23.26 high-entropy alloys in Hanks' solution at 37 degrees C for potential biomedical applications. Al7Cr23.26Fe23.26Co23.26Ni23.26 shows higher corrosion resistance than Ti-6Al-4 V alloy due to the formation of a stable p-type passive film composed of various oxides, resulting in low vacancy concentration and limited ion conductivity. Al20Cr5Fe50Mn20Ti5 exhibits an n-type passive film composed of oxides that promote chloride ions adsorption and diffusion-controlled corrosion.

Summary: This study explores the application of Eucalyptus leaves extract (ELE) as an anticorrosive agent for aluminium alloy in 0.5 M HCl. The results show that ELE has excellent inhibition efficiency at a concentration of 0.5% ELE at 303 K. The adsorption of ELE on the metal surface follows the Langmuir adsorption isotherm models. The corrosion inhibition mechanism involves charge transfer control and ELE acts as a mixed-type inhibitor.

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: The corrosion behavior of antimony in sulfuric acid solution and the stability of the anodic-generated coating on its surface were studied using various techniques. The results showed that the anodic layer development on the antimony surface occurs via a low-field migration mechanism. The pre-immersion oxide film and the anodic-produced layer on antimony were found to be prone to dissolution in concentrated acid solution. Additionally, the thermodynamic parameters for the corrosion of antimony in concentrated acid solution were calculated.

Summary: Ti6Al4V alloy is widely used in orthopaedic applications due to its excellent properties, but long-term exposure to body fluid can cause corrosion. In this study, thermal oxidation was performed on micro-blasted Ti6Al4V surfaces to minimize corrosion. The combined mechanical and thermal process increased surface roughness and improved the hydrophilic nature of the Ti6Al4V surface. Formation of metastable Ti2O3 and transformation of anatase and rutile TiO2 enhanced corrosion resistance. Micro-blasting with 48-hour thermal oxidation showed significantly higher corrosion resistance and reduced corrosion rate compared to untreated Ti6Al4V.

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.
