Nevertheless, the poor intrinsic electronic/ionic conductivity and low redox activity restrict these materials' reversible capacity and rate performance. Herein, amorphous NiO-coated NiCo metallic organic framework nanosheets (NiCo-MOF/NiO) which combine the advantages of heterostructure and two-dimensional structure are fabricated via a simple hydrothermal reaction and atomic layer deposition. In general, the two-dimensional structure accelerates the diffusion of ions along the material surface, resulting in rapid ion diffusion kinetics. In-situ Raman results suggest that constructing heterostructure can improve the redox kinetics of NiCo-MOF and facilitate the oxidation of Ni ions toward high valence state, leading to effectively boosted capacitance. As a result, the NiCo-MOF/NiO electrode with optimized Ni/Co ratio and NiO coating thickness exhibits a high areal capacitance of 3010 mF cm⁻² at 5 mA cm⁻² and remains 62.5 % of initial capacitance over 5000 cycles, much better than that of pure NiCo MOF (2150 mF cm⁻²). In addition, the asymmetric supercapacitor (ASC) constructed with NiCo-MOF as the positive electrode and commercial activated carbon (AC) as the negative electrode exhibits a large operating voltage window of 1.6 V, with an areal capacitance of 34.4 mF cm⁻² at a current density of 11 mA cm⁻², and retains 77.8 % of its initial capacity after 5000 cycles.

This study assesses the performance of Mo/FeCrAl bilayer and FeCrAl single-layer coatings, which have been deposited onto zircaloy-4 by magnetron-sputtered. The study involved a comparative analysis of the coatings' corrosion behavior in high-temperature and high-pressure (HTHP) water at 360 °C and 18.6 MPa, as well as their oxidation resistance at temperatures between 1000 °C and 1200 °C. The Mo sublayer can only function as a barrier layer under certain conditions, effectively exhibiting the material characteristics of a Mo alloy at high temperatures. Under HTHP water conditions for 14 days, a mixed oxide layer of Fe₂O₃ and Cr₂O₃ formed on the surface of the FeCrAl coating, with numerous cracks. In contrast, the Mo/FeCrAl bilayer coating demonstrated superior protection due to the formation of a dense, continuous FeCr₂O₄ spinel layer, effectively shielded the zirconium alloy substrate from corrosion. When exposed to high-temperature steam, the FeCrAl coating underwent a severe Fe-Zr eutectic reaction, leading to coating failure. Meanwhile, the Mo/FeCrAl coating underwent structural evolution. A continuous Al₂O₃ layer formed on the surface, and the MoFe₂ Laves phase precipitated at the grain boundaries of the FeCrAl layer. This significantly hindered the diffusion of Fe and O ions and further reinforced the coating's structure. Additionally, a thermally stable FeMo layer was present at the Mo/FeCrAl interface, and a ZrMo₂ layer formed continuously at the Zr/Mo interface, creating a diffusion barrier and preventing detrimental low-melting-point eutectic reactions. These findings corroborate the crucial role of the Mo barrier layer in enhancing the protective capabilities of the FeCrAl coating. Empirical evidence suggests the potential adoption of Mo/FeCrAl coatings for zirconium alloy cladding, offering outstanding corrosion resistance and high-temperature oxidation resistance crucial for extending the lifespan of materials in extreme environmental conditions.</div></div>","PeriodicalId":22009,"journal":{"name":"Surface & Coatings Technology","volume":"497 ","pages":"Article 131733"},"PeriodicalIF":5.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Originally, they featured distinct balances of α, β and α” phases. To probe the heating effects on the bulks, the alloys were thermally treated (TT) at the same nitriding temperatures. They disclose a strong structural and microstructural dependence with the nitriding temperatures and niobium fractions, which intricately rule the mechanical properties of both bulks and layer/substrate systems. The nitriding produces ∼1 μm thick nitride layers (TiN, Ti₂N) at top surfaces, with high hardness (<em>H</em>) and elastic modulus (<em>E</em>). Beneath lie β-rich regions, spread over 20–50 μm thick layers, with embedded α_N precipitates whose size vary inversely with the Nb wt% and heating conditions. These layers formation involve a competing effect between N and Nb, which are α and β stabilizers, respectively.

The <em>H</em>/<em>E</em> ratio, an indicative of tribological resistance, increases in all the nitrided surfaces, while it diminishes in the TT bulks. The overall conclusion is that parameters must be carefully chosen for each Ti<img>Nb composition.

Similarly, when operating in a corrosive environment such as near sea, corrosion plays a major role. The corrosion process on pristine and eroded surfaces can be different. So, corrosion studies on eroded surfaces are important to understand compressor blade deterioration by erosion and corrosion. It is important to develop a coating that can protect the compressor blades from SPE and corrosion. Ternary nitrides are known to have a complementary effect of two different metal nitrides. Further, the multilayer coating architecture with altering mechanical properties across the thickness contributes to combat SPE and corrosion. Considering these key factors, nano-multilayered TiCr/TiCrN coating of thickness ~8.5 μm with a bi-layer thickness of 7.5 nm was developed using an in-house designed unbalanced magnetron sputtering system. The optimized coating exhibited good adhesion and mechanical properties. The SPE tests were carried out following ASTM-G76 standards in the temperature range of room temperature (RT) to 500 °C.

Enhancing the hydrophilicity of intrinsically hydrophobic membranes is crucial for improving their antifouling performance through a simple modification. In this study, inspired by the natural mechanisms of saltwater fish and mussels, an antifouling zwitterionic surface was fabricated via co-assembly of a novel N-oxide zwitterionic copolymer (PTODA) and dopamine (DA). The zwitterionic groups in PTODA with the direct link between opposite charges (N⁺-O⁻) create a strong hydration barrier by interacting with water molecules, effectively resisting oil adhesion and enhancing oil-water emulsion permeability. Moreover, the self-polymerization and interaction of catechol groups within DA and PTODA during the co-deposition progress could facilitate the stable anchoring of the zwitterionic copolymer onto the membrane. As expected, the modified membrane thus exhibits excellent hydrophilicity, underwater superoleophobicity, and oil-fouling resistance.
