Abstract

See full text

The present disclosure discloses a method for realizing macroscopic super-lubrication by a matching pair of nano metal-coated steel balls and hydrogen-containing carbon films, which is based on the use of nano metal-coated steel balls and diamond-like films with a hydrogen content of 25-30% as the matching pair. Further, a tribochemical reaction occurs through the catalytic action of nano metal during the friction process to form a nano graphene transfer film with incommensurate contact at the contact interface to achieve macroscopic super-lubrication.
