ABSTRACT

Carbon nanomaterials have attracted great interest for their well-established friction and wear performance. This chapter introduces four typical carbon nanomaterials, namely fullerenes, carbon nanotubes (CNTs), graphene, and nanodiamonds, which have been widely studied for their roles in advanced lubrication systems, and highlights recent progress in using each carbon nanomaterial for various tribological applications, such as anti-wear enhancement and friction reduction for coatings, improvement of tribological behaviors for bulk materials, additives in lubricants, and superlubricity. It also discusses emerging carbon nanomaterials including carbon quantum dots, nano-onions, and nano-horns used for the reduction of friction and wear. Finally, it concludes with an outlook of future studies for carbon nanomaterials on tribological issues, including key challenges in tribology and possible solutions.
