Lubricants, consisting of base oils and additives play a crucial role in enhancing the component reliability by reducing friction and wear. Graphene as additive has shown tremendous improvements in lubricants performance. From industrial application viewpoint, there is a need to produce graphene in large-scale instead of conventional smaller quantities. However, large-scale production of graphene has yet to be implemented partly because most approaches currently initiated from graphite, which is a very expensive raw material for graphene. This is the first time we plan to investigate the capability of coal waste derived graphene as an additive to develop novel low viscosity engine oil for unmanned aerial vehicles. We revealed that the surface protection, friction and wear mechanisms under graphite additized lubricants with varied weight percentages of coal derived graphite under UAV Piston engine simulating contact conditions could perform better than standalone PAO base oil.
