Onion-like carbon films endow macro-scale superlubricity

Onion-like carbon films were prepared by constant current high-frequency dual-pulsed plasma enhanced chemical vapor deposition technique. Owing to the unique carbon onions both in bulk and debris of nanostructured carbon matrix, the films not only showed a super-high elastic recovery up to 92%, but also obtained a super-low friction coefficient below 0.01 and wear rate about 6.41â?¯à?â?¯10â??18â?¯m3/Nm in ambient atmosphere. The carbon onions achieved an incommensurate contact and played as â??molecular bearingâ? in the friction process, resulting in both super-low friction and wear rate.
