F92 steel is widely used for critical components such as valves and power generation equipment, where improved surface hardness and wear resistance are required for enhanced durability. Conventional quenching methods can increase hardness; however, they often suffer from limited effective hardening depth and poor dimensional controllability. In this study, a laser quenching strategy assisted by a laser textured light trapping surface texture is proposed to enhance the depth and properties of the quenching-strengthened layer in F92 steel. The results show that, under the synergistic effect, the surface reflectivity was significantly reduced from 50.0 % in the original sample to 5.7 %, greatly improving the laser energy absorption efficiency and increasing the quenching depth from 1.0 mm to 2.5 mm. After laser quenching with surface texture, the samples exhibited finer grains, lower residual austenite content, higher dislocation density, and the formation of oxygen solid solution in matrix, compared with water quenched and directly laser quenched samples. The hardness of the sample with the light trapping texture increased to 952.8 HV_0.5 after laser quenching, while the wear rate decreased to 4.13 × 10⁻⁵ mm³·N⁻¹·m⁻¹. Overall, the laser quenched sample with light trapping surface texture exhibited the best hardness and wear resistance, providing a new approach for the surface strengthening of materials such as F92 steel.

F92钢广泛用于阀门和发电设备等关键部件，这些部件需要提高表面硬度和耐磨性以增强耐用性。常规淬火方法可提高硬度；但其有效硬化深度有限，尺寸可控性差。为了提高F92钢淬火强化层的深度和性能，提出了一种利用激光织构光捕获表面织构辅助的激光淬火策略。结果表明：在协同作用下，表面反射率从原始样品的50.0%显著降低到5.7%，激光能量吸收效率大大提高，淬火深度从1.0 mm增加到2.5 mm；经过表面织构的激光淬火后，样品的晶粒更细，残余奥氏体含量更低，位错密度更高，基体中形成了氧固溶体。激光淬火后，具有光捕获织体的样品硬度提高到952.8 HV0.5，而磨损率下降到4.13 × 10−5 mm3·N−1·m−1。综上所述，具有光捕获表面织构的激光淬火样品具有最佳的硬度和耐磨性，为F92钢等材料的表面强化提供了新的途径。

This study demonstrates a laser-driven precision manufacturing approach for tunable wettability surfaces by direct conversion of polyimide films into laser-induced graphene (LIG) with hierarchical microstructures. By precisely controlling Ytterbium fiber laser parameters, the reversible transition between superhydrophilic (contact angle ≈ 15°) and superhydrophobic (contact angle ≈ 155°, hysteresis < 5°) states is achieved. Comprehensive characterizations reveal that the non-monotonic wettability transition results from the synergistic evolution of carbonization degree, surface chemistry, and hierarchical roughness. The grid-like LIG structures fabricated at 70 W power exhibited optimal superhydrophobicity due to their unique combination of high sp² carbon content, minimal oxygen content, moderate surface roughness (Sa = 15.27 μm), high fractal dimension (Df = 2.35), and optimal feature aspect ratio (1:4.2). The process exhibited excellent reproducibility (contact angle standard deviation <±2° across 10 samples) and environmental stability (contact angle remained >150° after 30 days of ambient exposure). This approach enables rapid, mask-free fabrication of functional surfaces with tunable wettability for applications in anti-icing, liquid transport, and microfluidic devices.

本研究展示了一种激光驱动的精密制造方法，通过将聚酰亚胺薄膜直接转化为具有分层微结构的激光诱导石墨烯（LIG），来制造可调润湿性表面。通过精确控制镱光纤激光器参数，实现了超亲水性（接触角≈15°）和超疏水性（接触角≈155°，迟滞<； 5°）态之间的可逆转变。综合表征表明，非单调润湿性转变是炭化程度、表面化学和分层粗糙度协同演化的结果。在70 W功率下制备的网格状LIG结构具有高sp2碳含量、低氧含量、中等表面粗糙度（Sa = 15.27 μm）、高分形维数（Df = 2.35）和最佳特征长宽比（1:4.2）的独特组合，具有最佳的超疏水性。该工艺具有出色的重现性（10个样品的接触角标准偏差为±2°）和环境稳定性（接触角在环境暴露30天后保持为150°）。这种方法可以快速、无掩膜地制造具有可调润湿性的功能表面，用于防冰、液体输送和微流体装置。

The industrial realization of high-efficiency perovskite/silicon tandem (PST) solar cells hinges on scalable, low-temperature fabrication of complex electron contact architectures. Here, we report a hybrid spatial atomic layer deposition (SALD) and physical vapor deposition (PVD) platform that enables the sequential, vacuum-based deposition of AlO_x/C₆₀/SnO_x electron contact stacks over G12 wafer formats. The system integrates a custom-designed linear evaporator into a high-throughput SALD reactor, allowing precise control of layer thickness and uniformity. Real-time ellipsometry provides in-line monitoring, revealing growth delays of SnO_x on hydrophobic C₆₀. Photoluminescence measurements demonstrate that AlO_x passivation significantly enhances quasi-Fermi level splitting. This work establishes a scalable, inline-compatible process for next-generation tandem photovoltaic devices.

In this study, to ensure the service performance of laser cladding remanufactured gears under severe operating conditions, the wear resistance of the surface coating was enhanced through a fine grain strengthening mechanism. A quadratic regression model linking process parameters to grain size was established via response surface methodology (RSM). This model was employed to investigate and quantify the relationship between the processing conditions and the target response, thereby identifying the optimal parameters for achieving localized grain refinement within the coating. The microstructure and mechanical properties were systematically characterized to elucidate the relationship between microstructural evolution and the coating's tribological behavior. Experimental results demonstrated that the optimized coating possessed a markedly refined grain structure, with the average grain size reduced from 120.1 μm to 72.9 μm. The refined coating exhibited a gradient architecture comprising columnar dendrites with a random texture, which promoted the precipitation of solid-solution strengthening phases. Under the synergistic effects of fine grain strengthening and solid solution strengthening, the average hardness reached 625.3 HV_0.2. Simultaneously, the optimized coating exhibited outstanding friction and wear properties. The dry coefficient of friction for the roller specimen coating decreased from 0.249 to 0.185, and the wear volume decreased from 0.0519 g to 0.0161 g. The dominant wear mechanism transitioned from severe adhesive wear to mild fatigue wear.

在本研究中，为了保证激光熔覆再制造齿轮在恶劣工况下的使用性能，通过细晶强化机制提高表面涂层的耐磨性。利用响应面法建立了工艺参数与晶粒度的二次回归模型。该模型用于研究和量化加工条件与目标响应之间的关系，从而确定在涂层内实现局部晶粒细化的最佳参数。对涂层的微观组织和力学性能进行了系统表征，以阐明微观组织演变与涂层摩擦学性能的关系。实验结果表明，优化后的涂层晶粒结构明显细化，平均晶粒尺寸从120.1 μm减小到72.9 μm。细化后的涂层呈现出由随机织构的柱状枝晶组成的梯度结构，促进了固溶强化相的析出。在细晶强化和固溶强化的协同作用下，平均硬度达到625.3 HV0.2。同时，优化后的涂层具有良好的摩擦磨损性能。涂层的干摩擦系数从0.249降低到0.185，磨损量从0.0519 g降低到0.0161 g。主要磨损机制由严重黏着磨损向轻度疲劳磨损转变。

Cutting and forming tools operating under high load conditions often suffer from premature wear. Applying hard, wear-resistant coatings particularly multilayer coatings can significantly enhance their functional properties. In this study, three multilayered coatings were deposited on hardened M2 steel bars using arc-evaporation: (1) TiN/TiCrN/TiN, (2) TiN/TiCrN/(TiN/CrN)₁₀/TiN system and (3) (Cr/CrN)₂₅. Mechanical (nanoindentation), tribological (cylinder on cylinder reciprocating tests) behavior of the coatings was investigated along with micro-impact tests. SEM/TEM analysis of the coatings revealed dense and fine-grained columnar structure in the direction of growth. All multilayer coatings showed enhanced wear resistance compared to the TiN monolayer. The TiN/TiCrN/TiN system exhibited the highest hardness (30.6 GPa) and best wear resistance against Al₂O₃, with an 88 % reduction in volume loss compared to TiN. This performance is consistent with its high load-bearing capacity (H³/E² = 0.107 GPa), moderate H/E (0.059) and the lowest friction coefficient (<0.2). On the other hand, the (Cr/CrN)₂₅ coating demonstrated the best impact performance — with no chipping at 500 mN over 500 cycles and minimal damage at 1500 mN. This is attributed to its high H/E (0.074) and H³/E² (0.126 GPa) ratios, along with a relatively low modulus (310 GPa), much more closely matched (E_c/E_s ∼ 1.5) to the substrate than the other coatings.

在高负荷条件下工作的切削和成形工具经常遭受过早磨损。应用硬质耐磨涂层，特别是多层涂层可以显著提高其功能性能。在本研究中，采用电弧蒸发法在硬化的M2钢棒上沉积了三种多层涂层：(1)TiN/TiCrN/TiN, (2) TiN/TiCrN/(TiN/CrN)10/TiN体系和(3)(Cr/CrN)25体系。对涂层的力学性能（纳米压痕）、摩擦学性能（缸间往复试验）以及微冲击试验进行了研究。SEM/TEM分析表明，涂层在生长方向上呈致密的细晶柱状结构。与TiN单层相比，所有多层涂层的耐磨性都有所提高。TiN/TiCrN/TiN体系表现出最高的硬度（30.6 GPa）和对Al₂O₃的最佳耐磨性，与TiN相比，体积损失减少了88%。这与高承载能力（H3/E2 = 0.107 GPa）、中等H/E（0.059）和最低摩擦系数（<0.2）相一致。另一方面，（Cr/CrN）₂₅涂层表现出最佳的冲击性能-在500 mN下超过500次循环没有切屑，在1500 mN下损坏最小。这是由于它的高H/E（0.074）和H3/E2 （0.126 GPa）比，以及相对较低的模量（310 GPa），比其他涂层与基材更紧密匹配（Ec/Es ~ 1.5）。

In this study, we developed a glucose sensor based on a nanoflower platinum (nfP) film prepared via electrodeposition. The nfP film exhibited excellent electrochemical performance, achieving a high glucose detection sensitivity of 81.9 μA cm⁻² mM⁻¹ and demonstrating strong selectivity in phosphate-buffered saline (PBS) electrolyte. Beyond glucose sensing, the nfP film enabled electrochemical monitoring of glucose consumption as an indirect means of detecting cell activity. Chronoamperometry was employed to quantify the concentrations of Escherichia coli (E. coli) and MCF-7 cancer cells by measuring glucose depletion in the solution. The presence of E. coli resulted in a decrease in glucose concentration, which was captured through reductions in the chronoamperometric current. As the E. coli concentration increased from 10⁴ to 10⁶ CFU/mL, the corresponding charge measured at the electrode decreased linearly, with a strong correlation (R² = 0.999) described by the regression equation y = 755.5x – 2420.5. Similarly, MCF-7 cells exhibited a linear correlation (R² = 0.943) within the range of 10³ to 10⁵ CFU/mL. Overall, this work presents a simple and effective electrochemical strategy for glucose detection and cell monitoring, demonstrating promising potential for practical biosensing applications involving both bacterial and cancer cell analysis.

在这项研究中，我们开发了一种基于电沉积法制备的纳米花铂（nfP）薄膜的葡萄糖传感器。nfP薄膜表现出优异的电化学性能，对葡萄糖的检测灵敏度高达81.9 μA cm−2 mM−1，在磷酸盐缓冲盐水（PBS）电解质中表现出较强的选择性。除了葡萄糖传感外，nfP薄膜还使葡萄糖消耗的电化学监测成为检测细胞活性的间接手段。采用计时电流法通过测定溶液中葡萄糖的消耗来定量大肠杆菌和MCF-7癌细胞的浓度。大肠杆菌的存在导致葡萄糖浓度的降低，这是通过计时电流的减少来捕获的。随着大肠杆菌浓度从104 CFU/mL增加到106 CFU/mL，电极处测得的相应电荷量呈线性下降，相关性强（R2 = 0.999），回归方程为y = 755.5x - 2420.5。同样，MCF-7细胞在103 ~ 105 CFU/mL范围内呈线性相关（R2 = 0.943）。总的来说，这项工作提出了一种简单有效的葡萄糖检测和细胞监测电化学策略，展示了涉及细菌和癌细胞分析的实际生物传感应用的巨大潜力。

In this paper, we prepared series of DLC-Si films on 304 stainless steel by adjusting the flux of C₆H₁₈OSi₂ (HMDSO) using the high-power pulse magnetron sputtering (HiPIMS) system. The effects of different Si contents on the tribology performance and electrochemical properties of DLC-Si films were evaluated. The results suggested that the film showed favorable tribological properties and corrosion resistance with 9.26 at.% Si content, and this can be attributed to the incorporation of Si elements changed its graphitization ratio, friction chemistry, and plastic transfer behavior. Furthermore, the formation of hydrated silica gel during the friction process resulted in the lowest coefficient of friction (0.084) and wear rate (2.124 × 10⁻⁷ mm³/(Nm)) in seawater. Furthermore, i_corr of DLC film reduced three orders of magnitude (3.397 × 10⁻⁸ A/cm²) when compared to the 304 substrate, this is due to its inherent chemical inertness and the compact structure of films. The results suggested that the DLC-Si films with low friction coefficients and high corrosion resistance, could effectively prolong the service life of moving components in seawater environments. This provides a theoretical foundation for the application of these films in such environments.

本文利用大功率脉冲磁控溅射（HiPIMS）系统，通过调节C6H18OSi2 （HMDSO）的磁通，在304不锈钢上制备了系列lc - si薄膜。考察了不同Si含量对DLC-Si薄膜摩擦学性能和电化学性能的影响。结果表明，该膜具有良好的摩擦学性能和耐蚀性，耐磨性为9.26 at。这可归因于Si元素的加入改变了其石墨化比、摩擦化学和塑性转移行为。在海水摩擦过程中，水合硅胶的形成导致摩擦系数最低（0.084），磨损率最低（2.124 × 10−7 mm3/(Nm)）。此外，与304衬底相比，DLC薄膜的icorr降低了三个数量级（3.397 × 10−8 A/cm2），这是由于其固有的化学惰性和薄膜的致密结构。结果表明，DLC-Si薄膜具有摩擦系数低、耐腐蚀性能好等特点，可有效延长海水环境中运动部件的使用寿命。这为这些薄膜在此类环境中的应用提供了理论基础。

Severe wear of 42CrMo steel easily causes unstable power transmission, overload-induced fracture, and even serious safety accidents. Ultrasonic surface rolling process (USRP) is an effective method to enhance the tribological performance of 42CrMo steel due to the gradient nanostructure and surface texture. However, there still lacks a comprehensive understanding about the improvement contribution of tribological performance from surface texture and gradient nanostructure induced by USRP. This study reflects that USRP can effectively generate a gradient nanostructure (~50 nm) and a plastic deformation layer (~500 μm) on the surface. The detailed formation mechanism of the gradient nanostructure is composed of the synergistic effect of lath martensite segregation and dislocation intersection. Moreover, the function of surface texture undergoes a transformation with the increase of surface-strengthening pressure during the wear process: from debris storage-assisted wear resistance function to edge effect-induced wear acceleration function. Under less than 1200 N, wear debris storage induced by texture and gradient nanostructures synergistically improves the tribological performance of 42CrMo steel. Under more than 1200 N, the edge effect caused by the sharp texture becomes more pronounced, further accelerating the wear. These phenomena reveal competitive behaviors between positive impact of gradient nanostructure on enhancing the friction performance and negative effect from the damage at the texture edges. It also leads to a transformation of the dominant wear mechanism with the increase of pressure: from the initial abrasive and oxidative wear to slight abrasive wear accompanied by friction-protective oxide film, and finally to severe abrasive and oxidative wear.

42CrMo钢的严重磨损容易造成电力传输不稳定、超载断裂，甚至严重的安全事故。超声波表面轧制工艺（USRP）是提高42CrMo钢摩擦学性能的一种有效方法，因为它具有梯度纳米结构和表面织构。然而，对于USRP诱导的表面织构和梯度纳米结构对摩擦学性能的改善贡献，目前还缺乏全面的认识。研究表明，USRP可以有效地在表面生成梯度纳米结构（~50 nm）和塑性变形层（~500 μm）。梯度纳米结构的详细形成机制是板条马氏体偏析和位错相交的协同作用。在磨损过程中，随着表面强化压力的增大，表面织构的功能发生了转变，从碎屑储存辅助的耐磨功能向边缘效应诱导的磨损加速功能转变。在小于1200 N的条件下，织构和梯度纳米结构诱导的磨损屑沉积协同提高了42CrMo钢的摩擦学性能。在1200n以上时，尖锐的织构所产生的边缘效应更加明显，进一步加速磨损。这些现象揭示了梯度纳米结构对增强摩擦性能的积极影响和对织构边缘损伤的消极影响之间的竞争行为。随着压力的增加，主导磨损机制发生转变：从最初的磨粒和氧化磨损到轻微的磨粒磨损并伴有保护摩擦的氧化膜，最后到严重的磨粒和氧化磨损。

The viability of 5,5-dimethylhydantoin (DMH) and ethylenediaminetetraacetic acid (EDTA) as complexing agents in the electrolytic baths is systematically studied using experimental and theoretical approaches. The ZnNi alloy-based coatings were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), and nano-indentation studies. Cyclic voltammetry (CV) studies were carried out to study the electrochemical behavior and deposition kinetics of the electrolytic baths with and without the presence of additives. Density functional theory (DFT) calculations indicate that in DMH-based baths, the dissociation energy required to release Ni from the additives is higher than that for Zn, whereas in EDTA baths, Zn dissociates more easily than Ni. The diffusivity of Ni in baths containing EDTA is higher than in baths containing DMH, leading to higher amounts of Ni in the coatings obtained from EDTA baths (~16 wt% Ni). Furthermore, the coatings' texture analysis reveals a change in preferred crystallographic texture from {110}〈001〉 to {001}〈100〉 as the concentration of DMH increases from 0.1 to 0.5 M in the baths, differing from the coatings obtained from EDTA baths at all concentrations which displays {110}〈001〉 components.

采用实验和理论方法系统地研究了5,5-二甲基海因（DMH）和乙二胺四乙酸（EDTA）作为络合剂在电解液中的活性。采用扫描电子显微镜（SEM）、x射线衍射（XRD）和纳米压痕研究对ZnNi合金基涂层进行了表征。采用循环伏安法（CV）研究了添加和不添加添加剂时电解液的电化学行为和沉积动力学。密度泛函理论（DFT）计算表明，在dmh溶液中，从添加剂中释放Ni所需的解离能高于Zn，而在EDTA溶液中，Zn比Ni更容易解离。镍在含有EDTA的镀液中的扩散率高于含有DMH的镀液，导致EDTA镀液中镍的含量更高（~16 wt% Ni）。此外，涂层的织构分析显示，当DMH浓度从0.1 M增加到0.5 M时，涂层的首选晶体结构从{110}< 001 >变化到{001}< 100 >，这与EDTA在所有浓度下显示{110}< 001 >组分的涂层不同。

Metal corrosion presents significant economic and safety challenges in industrial applications, highlighting the demand for energy-efficient and sustainable protection strategies. Herein, we developed a synergistic protection system by coupling a sandwich-structured triboelectric nanogenerator (TENG) with cetyltrimethylammonium bromide (CTAB) inhibitor, which achieves dual protection through electrochemical polarization and the protective barrier. Two different sandwich-structured TENGs were designed using the same materials, but with distinct layer assembly configurations. The optimal structure was ultimately selected for the effective implementation of cathodic protection. The electric field generated by TENG can enhance the migration and adsorption of CTAB cations, thereby facilitating the formation of compact hydrophobic films that effectively reduce contact with corrosive species. Microscopic images and photographs were utilized to observe the corrosion morphology of the metal surfaces after the immersion experiments. Additionally, the fitted parameters obtained from electrochemical measurements were analyzed to assess the performance of the synergistic anticorrosion system. EDS and XPS were employed to conduct compositional analysis and quantify the adsorption amount of CTAB cations on the metal surface, while the contact angle was used to characterize the surface wettability. These results confirm that even when CTAB is used at a concentration below the effective protection threshold and the TENG-powered cathodic protection provides insufficient power supply, their synergistic integration still enables a noticeable anticorrosion effect. This work establishes a novel anticorrosion method that combines self-powered TENG technology with corrosion inhibitors, thereby addressing the issues of energy consumption and excessive consumption of inhibitor materials.

金属腐蚀在工业应用中提出了重大的经济和安全挑战，突出了对节能和可持续保护策略的需求。在此，我们开发了一个三明治结构的摩擦电纳米发电机（TENG）与十六烷基三甲基溴化铵（CTAB）抑制剂耦合的协同保护系统，通过电化学极化和保护屏障实现双重保护。使用相同的材料设计了两种不同的三明治结构的teng，但具有不同的层组装配置。最终选择最优结构，有效实现阴极保护。TENG产生的电场可以增强CTAB阳离子的迁移和吸附，从而促进形成致密的疏水膜，有效减少与腐蚀性物质的接触。利用显微图像和照片观察了浸泡实验后金属表面的腐蚀形貌。此外，还分析了从电化学测量中获得的拟合参数，以评估协同防腐体系的性能。采用EDS和XPS进行成分分析，量化CTAB阳离子在金属表面的吸附量，采用接触角表征表面润湿性。这些结果证实，即使CTAB在低于有效保护阈值的浓度下使用，并且由teng供电的阴极保护提供的功率不足，它们的协同集成仍然可以实现显着的防腐效果。这项工作建立了一种新的防腐方法，将自供电TENG技术与缓蚀剂相结合，从而解决了能源消耗和缓蚀剂材料过度消耗的问题。
