Summary: The atmospheric corrosion performance of S235 carbon steel exposed to the tropical/marine aerosol pollutants in Port Louis, Mauritius was evaluated. The study revealed significant corrosion concerns due to the distinct microclimate of Port Louis, situated on the northwest coast. The presence of sulphur dioxide emissions from heavy oil-fired power stations further complicated corrosion prediction. The analysis showed that the corrosion progression behaviors were influenced by environmental and geographical variables, with the formation of porous surface layers leading to increased metal dissolution.

Summary: Cold sprayed commercially pure Al-based coatings were applied on Mg-based alloys at different N2 gas temperatures. The porosity percentage of the coatings decreased and the flattening ratio increased as the N2 gas temperature decreased, due to in-situ tamping densification. This resulted in a noticeable reduction in wear rate of the Al-based coatings.

Summary: The oxidation behavior and kinetics of partially crystalline Si2BC3N were studied at high temperatures, revealing weight loss due to gas release and the formation of loose oxide scales. Compared to completely amorphous Si2BC3N, partially crystalline Si2BC3N exhibited inferior oxidation resistance, possibly due to changes in superficial chemical compositions and reactivity during crystallization.

Summary: A correlation between piezoelectricity and photoluminescence in europium doped (Na0.41K0.09Bi0.5)TiO3 ceramic was investigated, showing an optimum response at 1.0 at.% Eu doping concentration. While photoluminescence intensity increased with Eu concentration, a quenching effect on the hypersensitive 5D0 -> 7F2 transition was observed under an electric field in samples with lower Eu doping concentration.

Summary: The lack of an appropriate methodology has left unresolved many important issues related to miniature painting, particularly in terms of chemical degradation. Analyzing these paintings is challenging due to their fragility, variability of materials, and detailed execution. A non-invasive multi-analytical approach was proposed in this study to describe degradation processes caused by the interaction of lead pigments and oils.

Summary: The study showed that Ti1-x-yAlxTayN coatings have improved protective properties at 850 degrees Celsius, but this effect diminishes at 950 degrees Celsius. Additionally, it was found that the protective properties of the Ti1-x-yAlxTayN coatings deteriorate with increasing Ta content, with only the Ti0.41Al0.49Ta0.10N composition providing effective protection for the titanium substrate.

Summary: This study investigated the effect of high-temperature oxidation on porous ferritic stainless steel using synchrotron tomographic microscopy. The results showed that oxidation increased the specific surface area of the steel, with the highest increase observed for the sample processed at 850 degrees C for 100 hours. The study also revealed the formation of a network of connected channels within the sample due to open porosity, which dominated the volume.

Summary: In the last decades, various anodizing processes have been proposed for Mg alloys, with Electro-Chemical Oxidation (ECO) showing superior performance in terms of wear and corrosion resistance compared to Plasma Electrolytic Oxidation (PEO). This study investigates the influence of ECO treatment on the tribological behavior and cyclic mechanical performance of RE-containing Mg alloy EV31A-T6. The results show that ECO-treated alloy exhibits improved wear resistance, lower coefficient of friction, and higher fatigue strength compared to both untreated and PEO-treated alloys.

Summary: There is a lack of systematic studies on the correlation between alloy microstructure and mechanical failure for the AlSi10Mg alloy produced by laser-based powder bed fusion (L-PBF). This study investigates the fracture mechanisms of the alloy in different conditions and after various heat treatments. In-situ tensile tests combined with electron backscattering diffraction were conducted to analyze the crack nucleation and growth. The results showed that the T6 heat treatment formed a discrete globular Si morphology, which improved the mechanical performance due to the more homogeneous distribution of finer Si particles.

Summary: The San Carlo Colossus, known as San Carlone, is a monument made of wrought iron and copper. After more than 300 years of outdoor exposure, the iron elements of the monument showed minimal galvanic corrosion despite direct contact with copper. The study revealed that the corrosion resistance of the iron is due to its noble corrosion potential, while areas of corrosion were attributed to environmental factors.

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.
