Summary: Polyelectrolyte-coated magnesium alloy was prepared using layer-by-layer assembly with poly(allylamine hydro-chloride) (PAH) and sodium alginate (ALG). The influence of genipin as a crosslinking agent on the coatings' microscopic features and corrosion resistance was examined. The results showed that the crosslinked coating exhibited improved anticorrosive property and enhanced cytocompatibility, suggesting that crosslinking treatment could improve the performance of LbL assembled multilayer coatings.

Summary: The purpose of this study was to investigate the effect of Zn doped CaP coatings prepared by micro-arc oxidation method on MgCa1 alloy degradation. The results showed that the addition of Zn into CaP increased the corrosion resistance of MgCa1 alloy and enhanced the adhesion strength of the coatings. All samples exhibited cytocompatibility and the degradation rate of MgCa1 alloy in simulated body fluids (SBF) or DMEM was decreased by coating with CaP, which was further reduced by adding a small amount of Zn. The samples with CaP coatings and Zn doped CaP coating also demonstrated antibacterial efficacy against E.coli.

Summary: The influence of micro-sized Cr2O3 particles on the corrosion, mechanical, and thermal control performance of plasma electrolytic oxidation coated Mg was studied. The presence of more Cr2O3 particles in the coating resulted in enhanced thermal control and mechanical properties, along with slightly improved corrosion resistance and hardness. Additionally, increased concentration of Cr2O3 particles led to higher absorptance of the coating, possibly due to the low band gap of Cr2O3.

Summary: Magnesium (Mg) alloys have potential applications in improving fuel efficiency in automotive and aircraft industries due to their low density. However, the corrosion behavior of Mg and its alloys is a significant concern, and in this study, the addition of calcium (Ca) to wrought AM60 alloy was found to deteriorate corrosion resistance in a NaCl solution but improve it in the absence of Cl- ions. The study also discussed the impact of long-term immersion on corrosion behavior and alloy oxidation.

Summary: In this study, a polycaprolactone/hydroxyapatite (PCL/HA) composite coating was fabricated using a combination of hydrothermal and dipping methods to delay the degradation of magnesium alloy AZ31 as a bioresorbable material. The PCL/HA coating consisted of nano rod-shaped HA crystals and PCL filled in the space of HA crystals. Compared to the single HA coating, the PCL/HA composite coating showed improved binding strength to the Mg alloy and remained adhered to the substrate surface even after 38 days of immersion. The addition of PCL reduced the electrochemical corrosion rate of the HA coated sample by ten times, indicating that the PCL/HA composite coating provided a more effective barrier for the Mg substrate. The cytocompatibility evaluation using bone marrow-derived mesenchymal stem cells (BMSCs) and the antibacterial property evaluation using methicillin-resistant staphylococcus aureus (MRSA) showed that the PCL/HA composite coating exhibited better BMSC cell compatibility and had potential applications as a biological material. However, further improvement is needed for the antibacterial property of the PCL/HA composite coating in clinical applications.

Summary: In this research work, a Mg(OH)2 coating was formed on the surface of micro arc oxidation (MAO) coated AZ31 alloy through a low temperature hydrothermal method, incorporating sodium alginate (SA) and beta-cyclodextrin (beta-CD)@curcumin (Cur). The coating exhibited excellent corrosion protection, multi-antibacterial ability and almost no toxicity to the cells. The photothermal performance of the coating was achieved through the light absorption of encapsulated Cur by beta-CD, while SA enhanced the binding force between the drug and the substrate.

Summary: In this research, a self-assembled amorphous calcium carbonate (ACC)@curcumin (Cur) loaded polymethyltrimethoxysilane (PMTMS) coating on micro-arc oxidation (MAO) coated magnesium (Mg) alloy was proposed to overcome the issues of rapid corrosion and bacterial infection in using biodegradable Mg alloy for biomedical materials. The coating exhibited favorable corrosion resistance, dual antibacterial ability, and good biocompatibility. Cur was employed as an antibacterial agent and photosensitizer for photothermal therapy. The core of ACC significantly improved the loading of Cur and the deposition of hydroxyapatite corrosion products during degradation, thus enhancing the long-term corrosion resistance and antibacterial activity of Mg alloys.

Summary: This article validates a robust strategy based on damage-induced fluorescence enhancement effect to visualize dynamic damage-healing processes in anticorrosion coatings on magnesium alloy AZ31. Through embedding fluorescent poly-dopamine nanoparticles into thermo-responsive epoxy resin, immediate fluorescence was intensified at coating damages. The prepared coating possessed pronounced healing and corrosion protection capability with near-infrared irradiation, and the healing behavior can be traced and visualized based on the decrease in fluorescence intensity. This work opens a new avenue to monitor the failure and self-healing mechanism of anticorrosion coatings, providing guideline for engineering of next-generation smart protection materials.

Summary: The microstructure, mechanical properties, and degradation rates of LX11 and LX41 alloys were studied through optical microscopy, tensile tests, and electrochemical tests. The LX11 alloy exhibited finer grains, fewer twins, and smaller intermetallic phase volume fractions compared to the LX41 alloy. Increasing Li concentration resulted in a slight decrease in yield strength, a substantial increase in elongation, and a stable ultimate tensile strength for the Mg-Li-Ca alloys. LX11 alloy showed superior corrosion resistance compared to LX41 alloy. The release rate of metallic ions in Hank's solution cannot accurately reflect the corrosion rate of Mg-Li-Ca alloys due to the formation of corrosion products and their solubility difference.

Summary: This study investigates the corrosion behavior and mechanical properties of an extruded Mg-4Li-1Ca alloy under different micro-compressive stresses. The results show that micro-compressive stress can induce grain growth and precipitation of second-phase particles, accelerating the corrosion rate. However, when the stress level reaches a certain point, the volume fraction of the second phase becomes the dominant factor controlling the corrosion rate, and residual stress is released, forming corrosion product films that weaken the microstructural effect on corrosion behavior.
