Friction is the most important phenomenon that emerges in everywhere two surfaces in close proximity to each other moves. The resulting wear and release of thermal energy causes failures of engines. Wear and friction lead to a decrease in the performance of the mechanical system and most importantly lead to energy loss [1]. The most effective ways to control friction and wear, is lubrication which plays an important role in conserving energy. In recent years, nanoparticles such as pure metals, metal oxides, metal sulfides and carbon allotrops due to their potential in emission reduction and improving fuel economy are widely used as lubricant additives [2,3]. Among nanoadditives, molybdenum disulfide (MoS2) with lamellar individual atomically-thin planes that can easily slide against each other, holds special importance [4]. We have synthesized molybdenum-graphene nanocomposites and have investigated the synergistic effect of carbon allotropes and MoS2 on tribology properties of them (Fig 1).
