Summary: The effect of trace Ce addition on the microstructure evolution and corrosion behavior of dilute Mg-0.6Al-0.5Mn-0.25Ca alloys has been investigated. The addition of Ce resulted in the formation of less noble Al8Mn4Ce and Al11Ce3 phases. Notably, the alloy containing 0.3 wt% Ce exhibited the lowest corrosion rate, attributed to factors such as the low potential difference, compact composite oxide film, and enrichment of Fe.

Summary: This study characterized the pitting corrosion behavior of martensitic stainless steel with and without rare earth modification in NaCl solution. The presence of different inclusions in BASE and REM steels affected the pitting resistance, with REM steel showing both increased susceptibility to pitting nucleation and improved repassivation. The concentration of rare earth elements in the steel matrix influenced the number and size of inclusions, ultimately affecting the overall pitting corrosion resistance.

Summary: The study focuses on the biological impact and application of rare-earth elements (REEs) in biodegradable Mg-based biomaterials. Despite the effectiveness of REEs in improving corrosion, mechanical, and manufacturability properties of Mg alloys, their physiological effects are still poorly understood. The review provides guidance for the development of new biomedical alloys and emphasizes areas of concern and unclear knowledge. Key findings include current clinical and preclinical work summary, highlighting Sc as the most promising REE in terms of physiological impact, while caution is advised when considering other REEs as alloying elements.

Summary: To investigate the effect of milling time on the corrosion resistance of Mg65Zn30Ca4Pr1 alloy, powders were milled for 13, 20, and 70 hours, respectively. The samples were then sintered using spark plasma sintering (SPS) technology. Potentiodynamic immersion tests revealed that the samples milled for 13, 20, and 70 hours showed pitting corrosion, with Ecorr values of -1.36, -1.35, and -1.39 V, and polarization resistance (Rp) values of 144, 189, and 101 Ω, respectively.

Summary: The influence mechanism of rare earth elements Ce and Nd on the corrosion behavior of Mg alloy was studied by combining experimental characterization with first-principles calculation. The changes of work function and surface energy of the rare Earth phase and matrix phase in binary rare Earth Mg alloys Mg-0.3%Ce and Mg-0.3%Nd were investigated. The addition of light rare Earth elements Ce and Nd can improve the stability of the second phase, but has limited effect on corrosion behavior.

Summary: This study investigated the effect of yttrium and neodymium alloying on microstructure formation during severe plastic deformation and its impact on the mechanical and corrosion properties of binary Mg-3Y and Mg-3Nd alloys. The presence of Nd primarily caused precipitation, while Y remained dissolved in the magnesium matrix. The ECAP-processed W3 sample exhibited a combination of ultrafine-grain structure, weak crystallographic texture, high strength, and high 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.
