Carbon nanomaterials have piqued the interest of researchers over the last two decades due to their proven wear and friction properties, in addition to tribological application. This review provides a detailed analysis of the latest discoveries in tribology of four common carbon nanoparticles are carbon nanotubes (CNTs), graphene, nanodiamonds and fullerene. First, the four forms of carbon nanomaterials are described in terms of their applicability in coating for friction and anti-wears. Second, the use of graphene and CNTs as additions to improve tribological behaviours in bulk materials is discussed. Finally, the mechanisms of CNTs, fullerene, fullerene, nanodiamond and graphene, working as additive to lubricate to reduce wear and friction are discussed. Fourth, the advancements in super-lubricity employing carbon nanotubes and graphene are emphasised. Finally, this study finishes with a look ahead at future research on carbon nanoparticles in tribology, their major barriers for practical use, and prospective remedies.
