Abstract

Friction and wear remain as the primary modes of energy dissipation in transmission system. Here, the uniform coating of graphene on the diamond like carbon (DLC) surface is achieved with the effect of argon protection and low-temperature heating of the substrate. The generation of graphene nanoscrolls is induced by the dual function of high-contact stress at the friction interface and frictional heat. The results show that the Graphene/DLC coatings maintain a stable low friction coefficient (average friction coefficient < 0.03) for a long time in atmospheric, vacuum (Before and after AO and UV irradiation) environments.
