This study evaluates the efficacy of a micro-arc oxidation (MAO) layer combined with 3-glycidyloxypropyltrimethoxysilane (GPTMS) sealing in enhancing the corrosion fatigue behavior of ZE21B magnesium alloy in Hanks’ Balanced Salt Solution (HBSS). Electrochemical testing revealed a two-order-of-magnitude reduction in corrosion current density compared to bare alloy, while immersion tests demonstrated sustained protection against degradation. Corrosion fatigue experiments under cyclic loading showed stress-dependent performance: the composite coating improved fatigue life at low stress amplitudes (60 MPa) by mitigating corrosion pit formation, but interfacial weakness between GPTMS and MAO layers reduced performance at high stresses (90–80 MPa). Fractographic analysis identified asynchronous deformation and stress gradient-dependent coating spallation as key failure modes. These results provide mechanistic insights into coating degradation pathways and offer design strategies for developing robust surface modification systems to advance magnesium-based orthopedic applications.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"23 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144694096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their widespread adoption is significantly constrained by inherent limitations in mechanical properties. To address this challenge, this study introduces a novel Mg-based interpenetrating-phase composite reinforced with a nickel-titanium (NiTi) scaffold featuring a triply periodic minimal surface (TPMS) configuration. By combining experimental investigations with finite element simulations, we systematically elucidate the dual impact of the scaffold's unit cell size (<em>a</em>) on manufacturing viability and mechanical enhancement. To compensate for compromised infiltration dynamics induced by decreasing <em>a</em>, a critical permeability threshold of 1 × 10⁻⁸ m² is proposed for achieving successful composite fabrication. Mechanically, reducing <em>a</em> strengthens the interaction between the scaffold and matrix: the TPMS-configured NiTi scaffolds improve stress transfer, deflect crack propagation, and facilitate damage localization, whereas the Mg matrix preserves structural integrity and enables load redistribution. Consequently, the composites significantly outperform pure Mg, and lowering <em>a</em> leads to more substantial enhancements in compressive strength, energy dissipation, and deformation recoverability. This study offers valuable insight into the design and fabrication of high-performance Mg-based materials for structural and biomedical applications.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"68 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144652511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Directed energy deposition-arc (DED-arc) is a typical sub-rapid solidification process that contributes to the modification of the microstructure. In this paper, a series of novel Mg-3.0Nd-0.2Zn-0.3Zr-xCe (NZ30K-xCe) alloys with different Ce contents (0, 0.1, 0.3, 0.5 wt.%) were prepared by DED-arc. The results show that the experimental alloys have lower porosity (≤0.11 %). After adding 0.1 wt.% Ce, the average grain size decreases from 98.9 ± 5.7 µm to 49.8 ± 1.0 µm, and the texture is significantly weakened. Further additions of Ce (0.3 and 0.5 wt.%) do not lead to significant alterations in the average grain size and texture intensity when compared with the NZ30K-0.1Ce alloy. Grain refinement is related to the constitutional supercooling, and the texture weakening is connected to the solid solubility of Ce in the Mg matrix. The ultimate tensile strength and elongation of NZ30K-0.1Ce alloy are 37.2 % and 61.3 % higher than those of NZ30K alloy. Grain refinement and texture weakening are the reasons for the better strength-ductility of NZ30K-0.1Ce alloy.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"14 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144652513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a Mg-2 wt. % Zn-0.5 wt. % Y-1 wt. % Nd-0.5 wt. % Zr (ZE21C) alloy was used to prepare suture anchors, which were implanted into the patellar ligament proximal tibia of rats. The metabolic behavior of magnesium, zinc, and neodymium in the degradation products <em>in vivo</em> was analyzed through SEM, EDS, micro-XRF, and western blotting. These results indicate that Mg was rapidly metabolized and absorbed. However, Zn and Nd exhibited slow metabolic rates and accumulated as degradation products. This is mainly because the microenvironment generated by degradation inhibits metabolism by affecting the expression of cation-permeable channel proteins. This study analyzed the degradation and metabolic behavior of Mg alloys and provides a reference for the biological application of Zn as an alloying element.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"13 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144612928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formation mechanism of this gradient nanostructure (GS), the deformation mode and the strengthening effect were investigated in detail using TEM, EBSD and XRD. The results showed that microstructure evolution primarily underwent three stage to form the GS. In the early stage, deformation was dominated by a combination of multiple slip systems and twinning. In the intermediate stage, twins and coarse grains broke down into fine lath structures and smaller grains due to dislocation pile-ups and stacking faults (SFs). In the final stage, these fine grains were further refined into nanograins with the help of SFs. Compared with the original alloy, the introduced GS significantly enhanced the mechanical properties, and had a good work hardening capabilities. The strengthening mechanisms are primarily attributed to dislocation strengthening and grain boundary strengthening.

Here a novel self-supporting composite was constructed to address this issue by using chemically activated natural jujube wood-derived hard carbons (a-JHCs) with a three-dimensional (3D) network like skeleton as the artificial Mg-ions (Mg²⁺)-conducting interphase, achieving selective Mg²⁺ transport. Different from the traditional artificial solid-electrolyte interphase (SEI), the porous a-JHCs allows for 3D ion-conduction, thereby improving ion transport efficiency. Meanwhile, interfacial characteristics of a-JHCs have been demonstrated to suppress the intrusion of Mg deposits into micro-porous separators, allowing the Mg plating/stripping reaction beneath the interface. The artificial interface with low electronic conductivity significantly stabilizes the Mg electrode in conventional organic electrolytes.

In this investigation, we prepared SiC_P-reinforced magnesium matrix composites through optimized stir casting methodology and systematically investigated their thermophysical characteristics. Remarkably, the composite incorporating merely 25 vol.% SiC_P exhibited exceptional thermal performance metrics: a thermal conductivity of 178.5 W/(m·K) and a coefficient of thermal expansion as low as 16.8 × 10⁻⁶ K⁻¹.
