Graphite/Cu composite is widely used in pantograph slide plates. To further understand its lubrication behaviors, the tribological properties of graphite/Cu composites with different graphite content were studied using ball-on-disk wear tests. The results reveal that contain only and Cu phases. show friction coefficient rate 7 wt.% decreased 7.7% 12.7%, respectively, compared 5 graphite/Cu. However, both increased exceeding wt.%. excellent mainly attributed to synergistic action oxidative...
Abstract State‐of‐the‐art perovskite solar cells (PSCs) continue to encounter stability challenges throughout their current commercialization process, primarily due the instable organic components. Especially, surface (interface) imperfections, like undercoordinated Pb 2+ and halide sites, further compromise confinement of cations at provide a rapid pathway for ion migration volatilization, decreasing efficiency. Herein, study has developed Formamidine (FA) cation immobilization strategy...
Abstract Formamidinium (FA) based perovskites have emerged as one of the most promising light‐absorber layers for both single‐junction and advanced top‐cell tandem photovoltaics, owing to their precisely engineered electronic bandgap exceptional stability. However, because mismatch FA cation intricate crystallization FA‐based perovskite, formation an impurity phase is inevitable, which reduces efficiency Herein, a N‐Phenyl‐bis(trifluoromethanesulfonimide) (NPTFSI)‐assisted method presented...
Cu-Ni-graphite composites are intended for using as switch slide baseplates materials in high-speed railways industrials. The tribological characteristics of with different graphite content were affected by physical properties and generated variation correspondingly. It is difficult to study the correlation degree between means experiments. However, grey analysis (GCA) a suitable mathematic method researching each factor. In this study, prepared powder metallurgy (Cu-Ni-graphite slid against...
Fe2B-type boride exists in Fe–B alloy with a form of netlike, rod-shaped, or fishbone structure. This results high susceptibility to fracture. To improve the morphology Fe2B, various contents K2SO4 are added into an Fe-2wt%B alloy. The microstructure, mechanical properties and abrasion resistance modified have been analyzed systematically.The show that α-MnS forms alloy, increases increased relationship y = 1.68× + 0.03. Moreover, can act as effective heterogeneous nuclei M2B (where M...
A simple and systematic research development process were explained for ceramic additive manufacturing to obtain degradable scaffolds. First, the degradation rate of calcium silicate/β-tricalcium phosphate ceramics was controlled by adjusting component ratios. After soaking in simulated body fluid, many cluster-like silkworm pupa-like apatite deposits formed on surface prepared through dissolution-precipitation process. Meanwhile, deposition summarized. Then, according light-curing principle...
As-cast white cast iron specimens with chromium concentrations of 0, 2, and 4 wt% were prepared by melting casting. Scanning electron microscopy X-ray diffractometry results indicate that the composite phase consists a hard (cementite) toughness matrix (pearlite) 28.8 ± 2% cementite volume fraction, which is typical hypoeutectic structure. The pearlite microhardness increased higher content. maximum was 1,054.23 HV. Two-body abrasive wear measured under impact load using pin-on-disc...
