Switching from frictional to superlubricity regime

Studying particles sliding over a 2D potential lattice, researchers have observed a phase transition between a frictional regime and a frictionless, “superlubric” regime. Superlubricity—a regime in which the static friction between two surfaces vanishes—could improve […]

Currently, a large portion of consumed energy is used to overcome friction. Design of low friction components is a primary goal in building a sustainable society. Superlubricity, the state of ultralow friction (<0.01), has already […]

The Mechanism of Glycerol Superlubricity

09.05.2016 Aydar Akchurin 342 Views
Glycerol is a highly viscous liquid, generating friction coefficient of 0.1 and up for bearing steels in boundary lubrication. In full film EHL, pure glycerol generates high friction as well and therefore is rarely used […]
