Graphene oxide (GO) nanosheets and onion-like carbon (OLC) nanoparticles were synthesized from natural graphite powder candle soot, respectively, characterized by transmission electron microscopy Raman spectroscopy. The lubricating performances of GO OLC as lubricant additives in water comparatively evaluated using a ball-on-disc tribometer. effects sand blasting steel disc on its morphology tribological property evaluated. results show that the two nanomaterials, OLC, when used effectively...
The conversion from 2D X-ray to 3D shape holds significant potential for improving diagnostic efficiency and safety. However, existing reconstruction methods often rely on hand-crafted features, manual intervention, prior knowledge, resulting in unstable errors additional processing costs. In this paper, we introduce Swin-X2S, an end-to-end deep learning method directly reconstructing segmentation labeling biplanar orthogonal images. Swin-X2S employs encoder-decoder architecture: the encoder...
This paper deeply discusses the essence of our subjective existence and consciousness through conceptual analysis, makes assumptions analysis on how physical entities evolve into feedback system, system evolution process. First all, this analyzes from theoretical framework subject, expounds that subject is a direct real existence, change content Angle, which an equivalent to structural entity. Then, formation law various self-organization phenomena under evolutionary theory, evolved basic...
Superhydrophobic cobalt (Co) coating with micro-nanofiber structure was rapidly fabricated by a one-step electrodeposition process. The wettability, microstructure, and corrosion resistance of the as-prepared Co were evaluated under different test conditions. electrodeposited at 20 V for 5 min displays superhydrophobicity contact angle 160° sliding 6.2°. is derived from form myristate on its surface special structure. Excessive time or voltage change then decrease superhydrophobicity. can be...
The paper focuses on a novel friction material Cu-based powder metal material. Several elements, such as Al, SiO2, Fe, graphite, Sn, Mn, and MoS2 were added to the Cu developed by PM techniques. aim of experiment was study effect increasing Sintering temperature mechanical tribological characteristics train brake pads. materials prepared sintered at three different temperatures (850 °C, 900 950 °C). A high pressure pad-on-disk braking tester test wear behavior these without lubrication. Wear...
AbstractIn the present work, development of athermal ɛ martensite during quenching a low carbon Co–Cr–Mo alloy was investigated as function grain size. In addition, strain induced transformation (SIT) from fcc to hcp exhibited compressive plastic straining. It found that size exerts strong influence on resultant volume fractions and martensite. particular, fine sizes inhibit formation while promoting appreciable through SIT mechanism. Moreover, X-ray diffraction analyses indicated in 10 μm...
The adhesion force between two solid surfaces is of great interest with the rapid development micro–nanodevices and instruments. effect temperature on microscale has been studied by recording force–displacement curves an atomic microscope. A flat tip a diameter ~1.73 μm was used to prevent wear. measurements were carried out under ambient conditions in nitrogen-filled glove box. substrate varied 30 200 °C. results show that when <200 °C, influence normal spring constant cantilever can be...
This study proposed a physics-based heuristic modeling for the nonlinear constitutive relation of bolted joints based on Iwan model accompanying with rough surface contact theory. The approach led to an distribution function which possesses tribology-related features interface. In particular, break-free force Jenkins elements could be expressed in terms height asperities. considered contribution elastically, elasto-plastically as well plastically deformed asperities total tangential loads....
ABSTRACT Fatigue performance of reinforced concrete (RC) components strengthened with fibre polymer (FRP) is largely improved. However, temperature changes service environment have a great effect on the fatigue behaviour RC FRP. Concerning about variations in subtropical areas such as South China, this paper analyses beams carbon laminate (CFL) from experimental studies and theoretical analysis under four different temperatures (5 °C, 20 50 80 °C) five stress levels (0.60, 0.66, 0.72, 0.78,...
Cobalt alloys are currently employed in the development of hip implants due to their relatively good strength and wear properties. However, some instances exhibited rates excessive alloy modification improve this is possible. In present work, properties a cast wrought Co–Cr–Mo sliding against ultrahigh molecular weight polyethylene (UHMWPE) were investigated as functions implemented heat treatment. For purpose pin-on-disc testing machine was used. It found that athermal epsilon martensite...
