Excellent Water Lubrication Additives for Silicon Nitride To Achieve Superlubricity under Extreme Conditions

, 2019
Superlubricity has been recognized as the future of tribology. However, it is hard to achieve superlubricity under extreme conditions such as a high load and low sliding speed on the macroscale.

Origin of superlubricity of diamond-like carbon (DLC)

Friction
Hydrogenated diamond-like carbon (H-DLC) is typically produced as a coating or thin film through plasma-enhanced chemical vapor deposition (PE-CVD). H-DLC is relatively hard and well known to exhibit superlubricity.

Whole course oil-based superlubricity for polyetheretherketone-bearing steel sliding pair by introducing tribocatalytically active dialkyl-dithiophosphoric-modified copper nanoparticles in poly-alpha olefin oil

Friction
At present, achieving oil-based superlubricity depends on lubricating oil viscosity and rubbing pair materials excessively. Therefore, establishing a new route is of scientific significance and application value.

Superlubric sliding ferroelectricity

Applied Physics Reviews
Structural superlubricity at incommensurate van der Waals interfaces leads to ultra-low friction coefficients. In this study, we try to apply a similar strategy to reduce the barrier of sliding ferroelectricity in van der Waals bilayers/multilayers with commensurate interfaces, since the writing speed in ferroelectric memories would be enhanced almost ...

Evolution of tribo-induced interfacial nanostructures governing superlubricity in a-C:H and a-C:H:Si films

, 2017
Hydrogenated amorphous carbon (a-C:H) is capable of providing a near-frictionless lubrication state when rubbed in dry sliding contacts. Nevertheless, the mechanisms governing superlubricity in a-C:H are still not well comprehended, mainly due to the ...
