The underlying mechanisms of microstructural modification and comprehensive performance enhancement induced by remelting treatment are thoroughly elucidated. The findings indicate that while the dominant phase composition of the coating (FCC + TiC) remained unchanged after remelting, notable alterations occurred in the morphologies and spatial arrangement of TiC particles. Compared to the LC coating, the TiC particles in the LRM coating were considerably refined and more uniformly distributed, thereby minimizing their agglomeration and promoting stronger interfacial adhesion between the reinforcement and the matrix. Due to the reduced cooling rate during remelting, the grains exhibited stronger preferential orientation along with pronounced dynamic recrystallization, resulting in significant grain refinement. Concurrently, the proportion of high-angle grain boundaries (HAGBs) increased in the LRM coating, while the remelting process also mitigated stress concentration and enhanced coating stability. The refined morphologies and more uniform dispersion of TiC particles notably enhanced the nanohardness of the LRM coating, while maintaining its ability to bear loads and resist plastic deformation. Electrochemical tests revealed that both LC and LRM coatings exhibited corrosion resistance comparable to 316 stainless steel (SS), while the LRM coating demonstrated further improved anti-corrosion performance owing to its denser microstructure and optimized distribution of reinforcing phases. Furthermore, the combined improvement in mechanical strength and corrosion resistance imparted the LRM coating with outstanding resistance to cavitation erosion. Linear fitting analysis demonstrated that the cavitation erosion resistance (<em>Re</em>) exhibited strong correlations with both nanohardness (<em>H</em>) and corrosion current density (<em>I</em>_{<em>corr</em>}) (<em>R</em>² &gt; 0.9). Remarkably, the LRM coating maintained structural integrity after cavitation erosion testing, demonstrating exceptional service stability.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"348 ","pages":"Article 131550"},"PeriodicalIF":4.7,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145106862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the term “mineralization” is repeatedly applied in the manuscript in a manner inconsistent with mineralogical standards. The calcium phosphate layers formed during simulated body fluid (SBF) immersion are synthetic, amorphous, and laboratory-derived, and should instead be described as “calcium phosphate deposition”, “bioactive layer formation”, or “apatite-like phase development”. Second, the attribution of enhanced surface reactivity to Eu^³⁺ incorporation lacks proper validation. Since all glass compositions contain identical Eu_₂O_₃ concentrations, while SiO_₂ and CaO contents vary, the observed differences in apatite-like deposition likely arise from network connectivity and dissolution behavior, not europium alone. The absence of a Eu-free control limits any definitive conclusion about Eu^³⁺ effects. Finally, although the multifunctionality of Eu^³⁺ is emphasized, no experimental evidence of luminescence or osteogenic activity is provided, leaving claims of optical and biological benefits unsubstantiated. Addressing these issues would improve the accuracy, rigor, and practical relevance of the work, ensuring alignment with established terminology and enhancing its contribution to biomaterials research.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"348 ","pages":"Article 131537"},"PeriodicalIF":4.7,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145047002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome these limitations, we designed a self-supported three-dimensional (3D) heterostructured electrode of NiCoP₄O₁₂/MgCo₂O₄ (NCP/MCO) on Ni foam (NF). One-dimensional MCO nanowire arrays were first grown in situ as a robust, high-surface-area scaffold, followed by the uniform electrodeposition of zero-dimensional NCP nanoparticles to form a tightly integrated 3D network. The 3D network structure provides continuous electron-transport pathways, while the intimate contact at the NCP/MCO heterointerface further reduces charge-transfer resistance and facilitates ion diffusion, synergistically accelerating Faradaic kinetics and enhancing durability.
