Summary: To improve the corrosion resistance of magnesium alloy, Ca-Ph coatings were prepared on AZ31 alloy substrates by chemical conversion. The morphologies, compositions, and properties of the coatings were adjusted by treatment time and temperature. The coatings demonstrated significant corrosion protection to the substrate in the simulated body fluid (SBF) solution. The results indicated that higher temperatures favored the presence of hydroxyapatite and that the coating thickness had an enhanced influence on the corrosion performance.

Summary: Zinc alloys are a new generation material for orthopedic applications due to their physiological effects and degradation properties. However, excessive release of zinc ions during degradation and the inflammatory microenvironment hinder osseointegration. Therefore, it is crucial to modulate the release rate of zinc alloys and give them anti-inflammatory and osteogenic effects through surface modification technology.

Summary: Temperature is a critical parameter that affects the electrochemical reactivity and crystal nucleation/growth in the conversion treatment of Mg alloys. Increasing the operating temperature, however, reduces the reactivity of the bath and compromises the protective coating. Preheating the Mg substrate, on the other hand, does not change the chemistry of the bath. This study shows that preheating the Mg substrate to a temperature higher than the bath can effectively improve the protective coating due to enhanced crystal precipitation kinetics at the reaction fronts.

Summary: The effects of adding different amounts of AlN nanoparticles on the microstructural evolution and strengthening mechanisms of Mg-3Sn-1Ca based alloys were investigated. It was observed that increasing the amount of AlN nanoparticles led to a significant decrease in grain size. The presence of AlN nanoparticles refined the primary crystal phases and provided more nucleation sites for the formation of magnesium. Additionally, the nanoparticles restricted grain growth during solidification. The addition of AlN nanoparticles resulted in improved tensile properties and hardness at both room temperature and high temperature.

Summary: Heterogeneous TiC/AZ61 nanocomposites were fabricated to enhance both the strength and ductility of Mg matrix composites. The proportion of TiC-rich fine grain (FG) zones and TiC-rare coarse grain (CG) bands could be adjusted by changing the mechanical ball milling time. The composites achieved excellent mechanical properties with a volume fraction of 25% CG bands after 20 h of ball milling, which was attributed to the presence of geometrically necessary dislocations (GNDs) in the CG bands.

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: This study investigates the creep behavior and microstructural evolution of sand-cast Mg-14Gd-0.4Zr alloy using compressive creep tests. The results show that the coherent distribution of beta' and beta' (F) phases effectively impedes dislocation movement and enhances creep resistance. However, with increasing creep time, the fine precipitate chains coarsen and transform into different phases, leading to stress concentration and increased creep strain.

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.
