Macroscale Superlubricity of Hydrated Anions in the Boundary Lubrication Regime.

ACS Applied Materials and Interfaces, 2023
Cations can achieve excellent hydration lubrication at smooth interfaces under both microscale and macroscale conditions due to the boundary layer composed of hydration shells surrounding charges, but what about anions?

Generation mechanism of friction anisotropy by surface texturing under boundary lubrication

, 2020
Continuously variable transmission (CVT) is commonly used in automobile to reduce fuel consumption and emission. Apart from wider gear ratio, reduction of friction loss in a radial direction of the pulley surface is an effective method of improving CVT ...

Lubricity Synergism in Boundary Lubrication

World Tribology Congress III, Volume 1, 2005
Dimethyl Ether (DME) has been known as a ultra clean smokeless fuel for diesel engines for over a decade now. A significant challenge is to ensure full lifetime for the diesel engine injection equipment when handling the low boiling point DME as this fuel has very low viscosity and lubricity.

Boundary lubrication properties and contact mechanism of carbon/MoS2 based nanolubricants under steel/steel contact

Colloids and interface science communications, 2019
Lubrication mechanism of some carbon-based nanoparticles is unresolved and needs proper attention. In this work, friction and wear properties of carbon/MoS2 solid lubricants are tested in the boundary lubrication regime and further compared with oil ...
