Carbon allotropes are of prime interest to the field of tribology because of their peculiar structures and properties. In this article, a review of recent development in the research on the properties of carbon allotropes (fullerenes, diamond, graphite, and diamond-like carbon) is presented. In particular, their mechanical and tribological characterization is investigated in detail. It is observed that their tribological properties and behaviors are closely related to the structures and the environments. Among carbon allotropes, diamond-like carbon (DLC) coatings show sublimed characteristics including high stiffness and mechanical strength, self-lubricating properties, low friction coefficient, high thermal conductivity, high wear and corrosion resistance etc. DLC protective coating is thus a good candidate for applications to tribological engineering. The crystal structures, hydrogen content, deposition techniques, and environmental factors related to the tribological behaviors of DLCs are studied. This paper also details the tribological mechanisms and phase transformation of DLC films during sliding.
