Friction has memory

Experiments show that the friction between two surfaces depends on their history of contact and that this “memory” is reminiscent of the behavior of glasses. Contrary to what you may have learned in high school, […]

Switching from frictional to superlubricity regime

11.04.2018 tribonet 194 Views
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 […]

Graphene, a wonder just one atom thick material, shows incredible wear-resistance and super low friction levels. This behavior is ascribed to its low inter-layer shear properties and high normal load carrying capabilities. However, in many […]

Switchable Friction on Graphene

15.08.2016 Aydar Akchurin 140 Views
Graphene is a unique material in many aspects and has recently been applied in various ways. In tribology, it has been shown to lead to a superlubricity – an ultra low friction state. In laboratory […]
