Wear and friction of TiAlN/VN coatings against Al2O3 in air at room and elevated temperatures [PDF]

open access: yes, 2010
TiAlN/VN multilayer coatings exhibit excellent dry sliding wear resistance and low friction coefficient, reported to be associated with the formation of self-lubricating V2O5.

Clast collision frequency as an indicator of glacier sliding rate [PDF]

open access: yesJournal of Glaciology, 1997
Abstract The mechanical interaction between a glacier and subglacial sediment can be observed using an instrumented rod that we refer to as the UBC ploughmeter. For clast-rich sediments, the rate of collision between clasts and a rod dragged through these sediments should be related to the glacier sliding rate. By

ANTISEIZURE CHARACTERISTICS OF LEADED ALUMINUM ALLOYS UNDER DRY SLIDING CONDITIONS

open access: yesJournal of Engineering, 2008
Aluminum-Silicon alloys, with soft lubricant metal, are considered to be one of the important tribological alloys which resist seizure. The effect of different lead percentages (1-20%Pb) that added to the modified eutectic Al-12%Si alloy on the wear ...

Complexity, rate, and scale in sliding friction dynamics between a finger and textured surface. [PDF]

open access: yes, 2018
Sliding friction between the skin and a touched surface is highly complex, but lies at the heart of our ability to discriminate surface texture through touch.

Landslide motion assessment including rate effects and thermal interactions: revisiting the Canelles landslide [PDF]

open access: yes, 2019
The re-activation of a large (40 Mm3) landslide on the valley slopes of a reservoir motivated a research initiative to estimate the risk of a fast-sliding mass moving into the reservoir.

Effect of Heat Treatments on Sliding Wear Behavior of Medium Carbon Steel [PDF]

open access: yesEngineering and Technology Journal, 2012
The aim of this work is to study the effect of heat treatments on the wear rate of the medium carbon steel which included normalizing and different quenching media (air, oil, salt solution at concentration %25). Quenching Include heating to a temperature

Non-monotonicity of the frictional bimaterial effect

open access: yes, 2017
Sliding along frictional interfaces separating dissimilar elastic materials is qualitatively different from sliding along interfaces separating identical materials due to the existence of an elastodynamic coupling between interfacial slip and normal ...

Non-Cyanide Electrodeposited Ag–PTFE Composite Coating Using Direct or Pulsed Current Deposition [PDF]

open access: yes, 2016
The effects of FC-4 cationic surfactant on electrodeposited Ag–PTFE composite coating using direct or pulsed currents were studied using scanning electron microscope (SEM), energy dispersive X-ray (EDS), optical microscope, and a linear tribometer.

ANOVA Study on Wear Parameters in Aluminum metal matrix Nano Composites [PDF]

open access: yesE3S Web of Conferences
In this paper, the effect of wear parameters on the wear rate of AA5086 alloy reinforced with Alumina (Al2O3) and Titanium boride (TiB2) is investigated.

How does a protein search for the specific site on DNA: the role of disorder

open access: yes, 2006
Proteins can locate their specific targets on DNA up to two orders of magnitude faster than the Smoluchowski three-dimensional diffusion rate. This happens due to non-specific adsorption of proteins to DNA and subsequent one-dimensional sliding along DNA.
