The formation of octonary DyErGdHoLuScTbY and senary DyGdHoLaTbY ErGdHoLaTbY high-entropy alloys (HEAs) with the hexagonal close-packed (HCP) structure was reported in this study. Experiments using scanning electron microscopy x-ray diffraction confirmed single HCP solid solution as-cast state for these three HEAs if presence minor rare-earth oxides due to contamination from processing is ignored. measured compressive yield stress values at room temperature are 245, 205, 360 MPa ErGdHoLaTbY,...
ABSTRACT In this article, the effects of different silane coupling agents: 3‐glycidyloxypropyltrimethoxysilane (GOTMS), 3‐aminopropyltriethoxysilane (APTES), and 3‐methacryloxypropyltrimethoxysilane (MPTS), on interface between polyimide (PI) silica (SiO 2 ), were investigated using molecular dynamic simulation. The results indicate that binding energy PI molecules SiO surface mainly comes from van der Waals interaction. Proper agents generate a thin membrane , which improves thickness...
The effects of polyimide with silica (SiO 2 ‐PI) and pores (porous PI) on the morphology, thermal, mechanical, tribological properties polytetrafluoroethylene (PTFE) composites were investigated. SiO ‐PI porous PI fillers decrease compactness PTFE matrices within PTFE/SiO PTFE/porous‐PI composites. In addition, improve interfacial bonding between matrices, which is opposite to detrimental effect fillers. Thermal mechanical deteriorated apparently. friction coefficients are 9.5% 8.5% lower...
Double-layer composite water-lubricated bearing is a new type of which can integrate the good damping performance low elastic under-layer bush and tribological plastic layer bush. This paper analyzes its elastohydrodynamic lubrication by fluid–structure interaction (FSI) method, studies effects eccentricity ratio, rotational speed, modulus distribution thickness on performance. Results show that double-layer more like bearing. As speed ratio increase, maximum water film pressure, load...
Yarn twist in textile technology is an important characteristic since it considerably affects the properties of knitted or woven fabrics. Many researchers have investigated effect staple-spun yarn on yarns and However, effects level Kevlar® 29 filament its resin-impregnated self-lubricating fabric liner are not fully known yet. In this study, we tensile tribological (Kevlar® 29/polytetrafluoroethylene fabric-resin composite). Two unexpected findings about been observed, namely (1)...
Abstract In this article, two different preparation methods were employed to explore the way maximize synergistic effect between polyimide (PI) and graphene (Gr) on friction wear of polytetrafluoroethylene (PTFE) composites. Results indicate that incorporation Gr into PI firstly is more beneficial for improvement tribological performance rather than blending PTFE firstly. The enhances resistance PI/Gr phases. fillers not taken away easily by plastic flow resin will accumulate surface PI/Gr....
The synergistic effect of silica (SiO 2 ) and copper (Cu) nanoparticles in polyimide (PI) on the friction interfacial deformation polyethersulfone/polyimide (PES/PI) blends was studied. Results indicate that SiO Cu tribological performance PES/PI nanocomposites is quite different from each other. addition into PI improves antifriction by 24.4%, but has little wear resistance. incorporation enhances resistance 55.5%, antifriction. achieve better comprehensive when content 0.8 wt 0.2 wt%,...
Abstract In this paper, the role of debris in formation polytetrafluoroethylene (PTFE) film was investigated using molecular dynamic simulation adhesion. The results indicate that internal structure PTFE could not be changed easily because strong cohesion debris. Debris will adhered on Fe surface by adhesion between and With transfer film, thin decreases gradually lower than matrix. difference friction pairs induce quite different adsorption behavior thick stable tends to matrix surface....
In recent years, slippery liquid infused porous surfaces (SLIPS) renowned for their exceptional repellency and anti-fouling properties, have garnered considerable attention. However, the instability of both structural integrity oil film severely restricts practical applications. This study is inspired by superwetting biological surfaces, such as fish scales, seashells, Nepenthes, to design fabricate a multiplex biomimetic robust lubricant-infused textured surface (LITMS) using laser-coating...
This article aims to evaluate the prospect of a new energy vehicle manufacturing stock market. We evaluated expected risk and return three companies through Conditional Value at Risk (CVaR) Capital Asset Pricing Model (CAPM). First, Asse
Herein, a new joining method for silk fabrics based on polymerization of polyurethane acrylate (PUA) photosensitive resin induced by nanosecond 355 nm ultraviolet laser is proposed. After the applied and cured, not only space between fiber bundles, but also gaps within bundles are filled up with resin, forming strong interlocking bonds. The infrared spectra joint area indicate that there no textile burning or chemical change fibers. increase energy density can improve degree strength....
Under the double-carbon target, smart distribution network (SDN) is important direction of future system development. Scientific and reasonable evaluation for SDN can effectively support its sustainable healthy Thus, a new methodology based on multi-criteria decision making (MCDM) was proposed in this paper to reflect comprehensive performance SDN. The green development high reliability were considered select evalution critertia. An index builded from four perspectives developement,...
