Wear transitions in a wear coefficient model [PDF]

open access: yesWear, 2009
The value chosen for the empirical wear coefficient in the frictional-work wear model greatly affects wear simulation results such as those for predicting rail corrugation growth. Furthermore, experimental results have widely shown that this wear coefficient is strongly dependent on the type of wear process involved, however these wear regimes are only

Triboemission of hydrocarbon molecules from diamond-like carbon friction interface induces atomic-scale wear

open access: yesScience Advances, 2019
Triboemission of hydrocarbon molecules such as methane and ethylene induces chemical and mechanical wear of diamond-like carbon. Understanding atomic-scale wear is crucial to avoid device failure.

Strain effects on the wear rate of severely deformed copper [PDF]

open access: yesarXiv, 2021
A variety of severe plastic deformation (SPD) techniques have been developed to process materials to high strains and impart microstructural refinement. High pressure torsion (HPT) is one technique that imparts inhomogeneous strain to process discs with low strain in the center and high strain at the outer edge. In the literature, this inhomogeneity is

Wear-resistant thin films of MRI-230D-Mg alloy using plasma-driven electrolytic oxidation [PDF]

open access: yesWear 271, 1987 (2011), 2017
Wear resistant coatings were produced on a permanent mould cast MRI 230D Mg alloy by (a) PEO in silicate based electrolyte, (b) PEO in phosphate based electrolyte, (c) hybrid coatings of silicate PEO followed by laser surface alloying (LSA) with Al and Al2O3, and (d) hybrid coatings of phosphate PEO followed by LSA with Al and Al2O3.

Critical length scale controls adhesive wear mechanisms

open access: yesNature Communications, 2016
The adhesive wear process remains one of the least understood areas of mechanics. While it has long been established that adhesive wear is a direct result of contacting surface asperities, an agreed upon understanding of how contacting asperities lead to
