Recent Progress on Carbon Nanomaterials for Resisting the Wear Damages

In recent years, carbon nanomaterials such as fullerenes, carbon nanotubes, graphene, and nanodiamonds have been regarded as versatile triboproducts such as copper coins for various engineering/commerce-scaled applications. Their large-scale usages as ideal reinforcements for the key tribomaterials are motivated by their huge interfacial areas, unique physical/chemical characteristics, as well as multiple scale load-transferring mechanisms. Numerous investigators have kept on studying the possibilities of using carbon nanomaterials as solid lubricants, lubricating additives, or the superlubricated push hand. This review offers a comprehensive discussion of up-to-date survey in carbon nanomaterials for achieving the low friction and high wear resistant in the forms of coatings, bulk materials, lubricants; or even superlubric state in the tribosystems from nanoscale to macroscale. Finally, important conclusions, foreseeable challenges, and future outlooks for carbon nanomaterials are highlighted as the concluding remarks that are needed to impulse nanotechnology maturation and developments of tribological fields such as copper coin protections.
