Overcoming friction and steps towards superlubricity: A review of underlying mechanisms

open access: yesApplied Surface Science Advances, 2021
Herein, we present a topical review of the advances and the mechanisms involved in achieving superlubricity - the regime of friction in which the coefficient of friction (COF) is less than 0.01. In light of the race towards achieving superlubricity on an

Macroscale Superlubricity Achieved With Various Liquid Molecules: A Review

open access: yesFrontiers in Mechanical Engineering, 2019
Superlubricity is generally classified as solid superlubricity and liquid superlubricity according to the lubricants involved at the interfaces, and is a popular research topic in tribology, which is closely linked to energy dissipation.

Superlubricity mechanism of diamond-like carbon with glycerol. Coupling of experimental and simulation studies [PDF]

open access: yes, 2007
We report a unique tribological system that produces superlubricity under boundary lubrication conditions with extremely little wear. This system is a thin coating of hydrogen-free amorphous Diamond-Like-Carbon (denoted as ta-C) at 353 K in a ta-C/ta-C ...

Molecular dynamics of cleavage and flake formation during the interaction of a graphite surface with a rigid nanoasperity [PDF]

open access: yes, 2009
Computer experiments concerning interactions between a graphite surface and the rigid pyramidal nanoasperity of a friction force microscope tip when it is brought close to and retracted from the graphitic sample are presented.

Superlubricity in Layered Nanostructures [PDF]

open access: yes, 2014
Interaction between two surfaces in relative motion can give rise to energy dissipation and hence sliding friction. A significant portion of the energy is dissipated through the creation of non-equilibrium phonons. Recent advances in material synthesis have made the production of specific single layer honeycomb structures and their multilayer phases ...

Photoinduced superlubricity on TiO2 surfaces

open access: yesFriction, 2023
Superlubricity control is of great interest in both industry and scientific research, and several methods have been proposed to achieve this goal. In this work, ultraviolet (UV) light was introduced into titanium dioxide (TiO2) and silicon nitride (Si3N4)

Role of surface roughness in superlubricity [PDF]

open access: yes, 2006
We study the sliding of elastic solids in adhesive contact with flat and rough interfaces. We consider the dependence of the sliding friction on the elastic modulus of the solids.

Superlubricity under ultrahigh contact pressure enabled by partially oxidized black phosphorus nanosheets

open access: yesnpj 2D Materials and Applications, 2021
Superlubricity has recently raised an increasing interest owing to its great potential in energy saving and environmental benefits. Yet how to obtain stable superlubricity under an ultrahigh contact pressure (>1 GPa) still remains a challenge.

Macroscale Superlubricity of Black Phosphorus Quantum Dots

open access: yesLubricants, 2022
In the present work, Black Phosphorus Quantum Dots (BPQDs) were synthesized via sonication-assisted liquid-phase exfoliation. The average size of the BPQDs was 3.3 ± 0.85 nm.
