Advances of Superlubricity

Superlubricity, as a new and an important area in tribology, has attracted more and more attentions from researchers over the world. In recent years, some new phenomena, new materials, and new mechanism both in liquid and solid superlubricity have been obtained. In the liquid area, a new system of superlubricity liquids has been found and the new mechanism has been proposed, which exhibits very good characteristics of superlubricity under the higher pressure. In solid area, more materials in superlubricity have been observed both by experiment and the molecular dynamics simulation (MDS), such as grapheme to grapheme surfaces, highly oriented pyrolytic graphite (HOPG) to grapheme etc. Mechanism for different tribo-systems has been discussed.
