At the beginning of bone remodelling, the coating exhibits promising antibacterial properties with 99.67% and 99.17% efficacy against S. aureus and E. coli, respectively, thanks to the singlet oxygen (1O2) and alkoxyl radicals (RO·) generated by the photodynamic effect of CuS@PPy heterojunction under low-power NIR light (1.5 W/cm2). In the bone reparative stage, the PCL-based coating can maintain high corrosion resistance to meet the mechanical requirements of Mg implants in human body fluid. However, after the complete rehabilitation of bones, through a high-power (2 W/cm2) NIR light, the PCL-based coating changed from an elastic to a viscous flow state (44.7 °C) under the photothermal effects of CuS@PPy, leading to quick degradation of the PCL-based coating and following accelerating dissolution of the Mg implant (avoiding secondary surgery).

Pure Mg shows a faster corrosion rate in simulated body fluid (SBF) compared to NaCl solution. Hydrogen evolution experiments indicate that the degradation rate of pure Mg in SBF decreases rapidly within the first 12 h but stabilizes afterward. The rapid deposition of low-solubility calcium phosphate on the pure Mg in SBF provides protection to the substrate, resulting in a gradual decrease in the degradation rates. Consequently, the corrosion product film of pure Mg formed in SBF exhibits a layered structure, with the upper layer consisting of dense Ca3(PO4)2/Mg3(PO4)2 and the lower layer consisting of Mg(OH)2/MgO.

The S-Ti3C2 exhibited pleasant catalytic effect on the hydriding/dehydriding kinetics and cyclic stability of MgH2.

We explored the underlying mechanisms and demonstrated that the Mg2+ and H2 from WE43 extracts could perform anti-inflammatory and anti-oxidative function after MCAO in mice, by increasing the expressions of IL-4, TGF-β1, SOD1 and decreasing the expressions of IL-1β, CXCR2, MDA.

The nucleation-growth Avrami model is employed to accurately model the hydrolysis kinetics, revealing improved hydrolysis yields and reaction rates following hydrogenation. Notably, CaMg2In0.1 has demonstrated exceptional hydrolysis characteristics, exhibiting a yield of 1140 mL/g, an initial hydrolysis rate of 113 mL/g·s, and an activation energy of 24.3 ± 1.7 kJ·mol−1. The yield of H-CaMg2In0.1 further escalates to 1800 mL/g with a rate of 221 mL/g·s, attributed to the formation of Ca4Mg3H14 and In phases subsequent to the hydrogenation of In2Ca and Mg3In phases in the alloy. These newly formed phases act as catalysts and actively participate in the hydrolysis process, providing active sites for hydrogen production, thus enhancing hydrolysis yields and kinetics. It is observed that with increasing In content, the order of hydrolysis performance of the alloy is as follows: CaMg2In0.1 > CaMg2In0.3 > CaMg2In0.5 > CaMg2In0.7, consistent with the trend after hydrogenation.

Increasing three parameters significantly expanded melting width and area, with a lower heat-affected zone under full penetration. And equiaxed grains gradually replaced columnar grains at the fusion line. More precipitate phases formed in the weld zone at the same time, inducing a greater hardness.

Although these evolutions had minimal impacts on tensile strength, elongation and yield strength exhibited a fluctuating state that initially decrease then raise.

In this study, ultra-fine-grained and homogeneous Mg alloys were fabricated using double-sided friction stir processing (DS-FSP) with liquid CO₂ rapid cooling, leading to a significant enhancement in the strength-ductility synergy of the stirred zone. The results demonstrate that DS-FSP samples exhibit simultaneous improvements in ultimate tensile strength (UTS) and elongation, reaching 334.1 ± 15 MPa and 28.2 ± 7.3 %, respectively. Compared to the non-uniform fine-grained microstructure obtained through single-sided friction stir processing, DS-FSP generates a uniform ultra-fine-grained structure, fundamentally altering the fracture behavior and mechanisms of Mg alloys. The DS-FSP samples exhibit irregular fracture patterns due to variations in basal slip system activation among different grains. In contrast, single-sided friction stir processing samples, characterized by a fine-grained yet heterogeneous microstructure, display flat shear fractures dominated by high-density dislocation initiation induced by twin formation, with fracture propagation dictated by the non-uniform texture. By achieving an ultra-fine grain size and homogeneous texture, DS-FSP effectively modifies the fracture mechanisms, thereby enhancing the strength-ductility balance of bio-magnesium alloys.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"23 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745198","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}
