Summary: Electrochemical and immersion tests were conducted to characterize the bio-corrosion resistance of as-extruded Mg-Ca binary alloys with submicron grain size. The microstructures were further characterized by optical microscopy (OM), scanning electronic microscopy and transmission electron microscope (TEM). The Mg-2Ca alloy extruded at 300 degrees C (2Ca-300) exhibits the lowest current density of 1.683 mA·cm-2 and corrosion rate of 22.14 g·m-2·day-1 in simulated body fluid, which is comparable with that of pure Mg. Ca addition can reduce grain size of as-extruded Mg alloy and decrease the corrosion rate. The formed Mg2Ca phases would accelerate the local galvanic corrosion and protect the alpha-Mg matrix simultaneously due to the lower electrode potential. The lower defect density, finer grain size, and weaker basal texture intensity contribute to the excellent bi-corrosion resistance of the 2Ca-300 alloy.

Summary: The application of magnesium alloys has received increasing attention in various fields, such as transportation, electronics, and biomedical engineering. The fabrication of superhydrophobic coatings on magnesium alloy surfaces is considered an effective way to improve corrosion resistance. However, the long-term durability and mechanical properties of these coatings have been major technical barriers. In this study, a calcium myristate coating with graphene oxide (GO) was successfully fabricated on AZ31 magnesium alloy through electrodeposition. The deposition time significantly influenced the morphology, thickness, wettability, corrosion resistance, and durability of the GO/Ca coating. The best corrosion resistance was achieved with a deposition time of 30 minutes, showing a significant reduction in corrosion current density and high impedance modulus, even after 21 days of immersion. The GO/Ca coating also exhibited good adhesion strength to the substrate. Considering its satisfying corrosion resistance, long-term durability, and high adhesion strength, the superhydrophobic coating on AZ31 alloy holds promise for anti-corrosion applications.

Summary: In this paper, the corrosion behavior and protective performance of a novel robustness mineralized layer on the surface of AZ80-0.38Nd (wt%) alloy were investigated. The results show that the mineralized layer exhibited excellent anti-corrosion property in the NaCl solution compared with the oxide layer, due to the outstanding impermeability. The mineralized layer also presented better corrosion passivation and micro-galvanic corrosion inhibition effects due to the characteristics of slight defects and good adhesion to matrix. Additionally, the mineralized layer could launch CO3- during degradation of corrosion, slowing down the penetration of Cl across the layer and inhibiting the attack on the mag-nesium substrate.

Summary: In situ-grown Mg-Al layered double hydroxide (LDH) films were obtained on an anodized AZ31 substrate by immersing the sample in different concentrations of Al3+ solution. The structure, composition, and morphology of the LDH films were analyzed, and their corrosion behavior was studied using electrochemical impedance spectroscopy (EIS). The results showed that the interconnected MgAl-LDH nanosheets formed a nest-like structure in the LDH film. LDH obtained in 0.032 mol center dot L-1 Al3+ solution had a dense laminated structure and effectively sealed the porous surface of the anodic oxide film. EIS results demonstrated that the corrosion resistance of the LDH-coated samples was significantly improved compared to the anodized alloy.

Summary: ZnAl-LDH-NO3 nanosheets were grown on MXene to inhibit its self-aggregation, and then mixed with epoxy resin and spun onto Mg PEO coatings. The resulting ZnAl-LDH-NO3@MXene nanocomposite exhibited long-term dispersibility and satisfactory sealing of the coatings. The synergistic effect between LDH and MXene nanosheets, along with the self-healing function provided by nitrate intercalation, contributed to the low wear rate and corrosion current density of the final coating. This work proposed a new strategy for MXene-based nanocomposites in anticorrosion/wear applications in epoxy coatings.

Summary: Novel turned-bearing extrusions (TBE) are developed to improve the strengths of AZ31 alloy sheets by introducing additional shear strain during preparation. Numerical simulations show that high strain leads to grain refinement through dynamic recrystallization (DRX), but also increases temperature and consumes dislocations. The SC-TBE sheet exhibits finer grains and a higher residual dislocation density compared to the DC-TBE sheet or conventional extrusion (CE) sheet. Overall, these findings provide insights for developing stronger Mg alloy sheets.

Summary: Graphene oxide (GO) lamellar membranes suffer from low flux and poor stability for practical applications due to tortuous transport pathways and weak interlamellar interactions. In this study, porous vermiculite (PVMT) nanosheets were incorporated into the GO-based membranes to establish fast and robust water-selective pathways. PVMT nanosheets provided in-plane pores, reducing the tortuosity and mass transport distance. The hydrophilicity and interlayer distance were enhanced by PVMT nanosheets, contributing to water-selective transport. The resulting membranes exhibited excellent dehydration performance with increased permeation flux and separation factor compared to pristine GO/PTFE membranes, while maintaining stability for 192 h operation. This study may inspire further research in constructing mass-transfer pathways within lamellar membranes.

Summary: The ageing behavior of as-extruded Ti-P/VW94 composites was studied. The peak hardness of the composites increased compared to the matrix alloy, with the 5% Ti-P/VW94 composite showing the highest peak hardness of 148.7 HV after aging for about 50 h. However, the hardness increments first decreased and then slightly increased with increasing Ti particle content due to the introduction of high-density dislocations by Ti particles.
