Advances in atomic-scale tribological mechanisms of solid interfaces

It is important to explain the triboligical mechanism of solid interfaces at the atomic scale. Theoretical models developments involving atomic-scale tribology and the most classical first-principles theory for atomic-scale friction have been described. The construction of potential energy surface based on first-principle calculation is found extremely useful to unveil the tribological mechanism for atomic-scale solid sheets. Furthermore, atomic-scale tribological mechanisms exploring achievements for metals interfaces, tribo-chemisty, carbon-based solid lubrication material and 2h-MoS2 have also been reviewed.
