Experimental evaluation of a silicone oil as an oxidation inhibitor for magnesium alloy under contact sliding at elevated temperatures [PDF]

open access: yes, 2022
This paper experimentally investigated the effects of silicone oil on the tribological behaviour of AZ31B/86CrMoV7 contact pair under a pin-on-disk configuration. A commercial silicone oil was used as an oxidation inhibiter for the AZ31B at elevated temperatures to 300 oC.

Correlation between test temperature, applied load and wear transition of Mg97Zn1Y2 alloy

open access: yesJournal of Magnesium and Alloys, 2021
Dry sliding wear tests were performed on Mg97Zn1Y2 alloy at various temperatures of 20, 50, 100, 150 and 200 °C using a pin-on-disc wear testing machine in order to reveal mild-severe (M-S) wear transition mechanism during elevated-temperature wear ...

Negative thermal expansion induced suppression of wear in dry sliding friction [PDF]

open access: yesPhys. Rev. E 102, 042801 (2020), 2020
Surface temperature is among crucial factors, which control wear during sliding dry contact. Using computer modeling, we study the possibility to achieve close to zero rate of surface wear during sliding friction of the special type of materials, which possess negative thermal expansion.

Wear mechanism of Cr3C2/Ni3Al composites showing excellent wear resistance

open access: yes工程科学学报, 2019
The Ni3Al intermetallic compound is considered an excellent wear-resistant material. The addition of Cr3C2 particles can further improve the wear resistance of Ni3Al-based alloys.

Design and development of a novel sliding friction and wear tester with complex working conditions

open access: yesScientific Reports, 2021
Serious wear phenomena occur in mining machinery under complex working conditions, and the wear of machine parts is primarily caused by the synergistic effect of adhesive wear, abrasive wear, corrosive wear, etc.

Adhesive wear with a coarse-grained discrete element model [PDF]

open access: yes, 2022
The use of molecular dynamics (MD) simulations has led to promising results to unravel the atomistic origins of adhesive wear, and in particular for the onset of wear at nanoscale surface asperities. However, MD simulations come with a high computational cost and offer access to only a narrow window of time and length scales.

Bionic design perspectives based on the formation mechanism of dental anti-wear function

open access: yesBiosurface and Biotribology, 2017
Human teeth are the important masticatory organ and therefore are subjected to friction and wear everyday. Both the loading condition and the environment are relatively complex in the mouth, however, normally human teeth can serve in mouth all their time

An in vitro study of the wear mechanism of a leucite glass dental ceramic

open access: yesBiosurface and Biotribology, 2015
Ceramics and glass-ceramics are materials of choice for dental crowns due to their attractive hardness, biocompatibility, etc. However, a major problem with their usage is the observed high wear of either the opposing dental enamel or both the enamel and

Breakdown of Reye's theory in nanoscale wear [PDF]

open access: yes, 2022
Building on an analogy to ductile fracture mechanics, we quantify the size of debris particles created during adhesive wear. Earlier work suggested a linear relation between tangential work and wear debris volume, assuming that the debris size is proportional to the micro contact size multiplied by the junction shear strength.

Wear-mechanism modelling [PDF]

open access: yes, 1993
Goals of the program are to calculate the surface temperatures in dry sliding, develop a soft wear tester for ceramics, survey the wear mechanisms in brittle solids, and couple the temperature calculations with models to give wear maps for brittle solids. (DLC)
