Leveraging trace nanofillers to engineer ultra-low wear polymer surfaces
Wear, 2021Abstract Trace nanofillers have proven unable to stabilize polymer surfaces due to their inability to reinforce the subsurface. Thus far, their effects on surface wear have been obscured by potentially unrelated subsurface mechanics. In this paper, we addressed this problem by first eliminating matrix (PTFE) subsurface instability with a secondary ...

Molybdenum disulfide/carbon multilayer films achieve ultra‐low wear in vacuum
Surface and Interface Analysis, 2023Although diamond‐like carbon (DLC) films are known for their low friction and wear properties in atmospheric environments, they commonly experience failure in vacuum environments. On the other hand, MoS 2 exhibits a low friction coefficient under vacuum conditions, but its columnar structure ...

Ultra-low wear rates for rigid-on-rigid bearings in total hip replacements
Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2000With the increased clinical interest in metal-on-metal and ceramic-on-ceramic total-hip replacements (THRs), the objective of this hip simulator study was to identify the relative wear ranking of three bearing systems, namely CoCr-polyethylene (M-PE), CoCr-CoCr (M-M) and ceramic-on-ceramic (C-C).

Tribology Letters, 2017
The wear rates of tribological polymers are strongly influenced by counterface roughness through competing mechanisms such as polymer abrasion by counterface asperities and mechanical engagement of debris into the features of the rough surface. Previous studies have shown that an ultra-low wear (k ~ 10−7 mm3/Nm) alumina–PTFE solid lubricant loses wear ...

Microstructure of tribologically induced nanolayers produced at ultra-low wear rates
Wear, 2007Abstract Wear in modern tribological systems is characterized by ultra-low rates in the order of a few nanometers per hour. Even under low wear conditions, morphology, crystalline arrangement, and chemical bonds of surface and subsurface are modified significantly and considerable plastic deformation occurs up to 1 μ m depth.

Thin films of fullerene-like MoS2 nanoparticles with ultra-low friction and wear
Nature, 2000The tribological properties of solid lubricants such as graphite and the metal dichalcogenides MX2 (where M is molybdenum or tungsten and X is sulphur or selenium) are of technological interest for reducing wear in circumstances where liquid lubricants are impractical, such as in space technology, ultra-high vacuum or automotive transport.

Wear and Friction Effects on Engine Materials of N-Butanol in Ultra-Low Sulfure Diesel Mixtures
International Journal of Surface Engineering and Interdisciplinary Materials Science, 2022The lack of the sulfur beneficial lubricity in ultra-low sulfur diesel (ULSD) may lead to premature wear and failure of diesel-fuel systems. Mixing of small percentages of, for instance, biodiesels and other biofuels is typically used to add lubricity in ULSD.
