Unidirectional transport of liquids has attracted the attention researchers in recent years for its wide application foreground. However, it is still a challenge to control spreading liquid, especially oils with relatively high viscosity. In this paper, flexible surface textured branch-shaped microstructures proposed. These asymmetric exhibit excellent unidirectional behaviors various oils. By suitably stretching different stretch ratios, length oil droplets can be controlled. Moreover,...
Purpose Scuffing is a severe form of adhesive wear that can lead to catastrophic surface damage in tribological systems. This paper aims investigate the failure mechanism scuffing and propose an effective engineering strategy enhance anti-scuffing performance frictional components. Design/methodology/approach Friction experiments were conducted under oil-lubricated conditions monitor behavior. The morphology parameters before after compared. Based on criterion, linear velocity load selected...
Investigating droplet wetting and icing behavior is crucial for comprehending the principles of surface design anti-icing surfaces. In this study, we present evidence from molecular dynamics (MD) simulations that reveal a hitherto unreported adhesion on surfaces with lattice constants 2.7 to 4.5 Å. Here, observe contact angles (CA) droplets face-centered cubic (FCC) consistently correlate positively constant. Further examination an idealized crystal reveals hydrophilic (e.g., CA = 85°)...
Purpose This paper aims to study different morphology Cu 6 Sn 5 effect on Babbitt alloy tribological properties. Design/methodology/approach Different of was conducted by cooling modes. Bare marked Babbitt-0, modified first mode (marked Babbitt-1) and second Babbitt-2). The microstructure microhardness specimens were tested. Then, properties Babbitt-1 Babbitt-2 performed reciprocating under lubricated condition. Findings results showed that shape changed from mixed needle star-like short...
ABSTRACT Graphene oxide/poly(ethylene glycol) (GO/PEG) composites that have biocompatibility and biodegradability properties been prepared to improve the lubrication of artificial joints, but they would be rapidly degraded absorbed by human body if injected. To prolong effect, GO/PEG lubricants were mixed into a chitosan (CS) sol, then GO/PEG/CS sol was added dimpled texture Co‐Cr‐Mo alloy transformed gel slowly release lubricants. The results friction experiments showed average coefficient...
Self-lubricating polymer–steel laminated composites (SLC) consisting of matrix zones and filled were fabricated by a laminating–bonding process. The silicon steel sheets the polymer with MoS2 graphite, respectively. control specimen was prepared spraying composite coating on GCr15 disc. tribological properties SLC investigated using ball-on-disc tribometer under different loads frequencies. Compared to specimen, friction coefficient wear rate reduced 57% threefold at 4 N 6 Hz, In addition,...
Babbitt alloy is a widely used bearing material. In order to improve its thermal and anti-fatigue performance, the combined effect of additive La heat treatment tin-Babbitt were studied. The microhardness, wettability, tribological performances first considered. modified with element (0.1 wt%) was prepared then carried out (marked by Babbitt). friction wear bare Babbitt, heated conducted ball-on-disc tester under oil lubricated condition. results showed that microstructure homogeneous. cubic...
Abstract Interface interaction between gallium-based liquid metal and copper-based materials results in the formation of intermetallic CuGa2 grains. In particular, grains are able to produce a uniform film newly formed holds peculiar characteristics, which have not been fully explored up now. this study, we present an electrochemical fabrication method situ on copper surface. Surface morphology chemical composition confirmed. Tribological experiments demonstrate that enables good...
Gallium-based liquid metal (GLM) is a promising lubricant candidate due to its high load capacity and thermal stability.
Purpose – This paper aims to optimize the operating condition of mechanical parts, whose working surfaces have macro-crack defects, and surface wear properties with macro-cracks are assessed through experimental investigation. Design/methodology/approach Macro-cracks perpendicular direction sliding were manufactured on discs by electric discharge machining. Tribological tests under oil lubrication conducted a ball-on-disc test rig. Their processes monitored on-line visual ferrography. The...
The artificial joint prosthesis’s surface is subjected to wear due the destruction of lubrication environment after surgery. In this study, an agarose-sodium hyaluronate hydrogel was used as lubricant additive in order supply and preserve lubricating fluid prostheses. A ball on disc experiment conducted using evaluate efficiency release rate under various frequencies. results showed that could pressure then absorb released decompression. Furthermore, acted effective transport mechanism...
