▎ 摘　　要

NOVELTY - The method involves ultrasonically dispersing non-defective graphene and nano-molybdenum disulfide in a solvent according to a mass ratio of 5:1-1:5 to form a uniform solution with a concentration of 10-100 Milligrams per Milliliters. The solution is dripped on a surface of a hydrogen-containing diamond-like carbon film. Friction experiment is carried out after the solvent is volatilized. The pair of ball is steel ball, alumina ball, silicon nitride ball and silicon carbide ball. The solvent comprises but not limited to de-ionized water, absolute ethyl alcohol, dimethyl formamide, N-methyl pyrrolidone, glycerol and phosphoric acid. USE - High bearing environment robust two-dimensional heterogeneous structure solid super-sliding method. ADVANTAGE - The method is simple, green and environment-friendly, greatly improving the friction performance of the diamond-like carbon film and realizing ultra-low friction from the vacuum environment to the humidity environment on the hydrogen-containing diamond-containing film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene Transmission electron microscopes (TEM) image obtained by highly ordered pyrolytic graphite (HOPG) mechanical directional shear preparation.
