▎ 摘　　要

NOVELTY - The carbon structure film-graphene additive solid-liquid composite, comprises fullerene-type carbon nanostructures, graphite-type carbon nanostructures or onion-type carbon nanostructures, and uses graphene nanoparticles as lubricating oil additives. The fullerene-type carbon nanostructures are obtained by plasma chemical vapor deposition of methane or acetylene at methane gas pressure of 14-18 Pa, methane to hydrogen pressure ratio of 1:1-1:3 and hardness of 18-31 GPa. The graphite-type carbon nanostructures are obtained by plasma chemical vapor deposition of methane or acetylene at methane gas pressure of 15-18 Pa, methane and hydrogen pressure ratio of 1:1-1:3 and hardness of 6-12 GPa. The onion-type carbon nanostructures are obtained by plasma chemical vapor deposition of methane or acetylene. USE - Carbon structure film-graphene additive solid-liquid composite used for reducing friction rate and wear rate in surface of metal, ceramic and polymer material used in high-end equipment and aerospace component. ADVANTAGE - The carbon structure film-graphene additive solid-liquid composite has long service life, sensitivity and reliability. DETAILED DESCRIPTION - The fullerene-type carbon nanostructures are obtained at pulse bias of 800-1200 V, conduction ratio 0.5-0.7 and frequency of 30-80 kHz. The graphite-type carbon nanostructures are obtained at substrate temperature of 150-350 degrees C, pulse bias of 800-1000 V, conduction ratio of 0.5-0.8 and frequency of 30-50 kHz. The onion-type carbon nanostructures are obtained at pulse bias of 1200-1500 V, conduction ratio of 0.5-0.8, frequency of 80-150 kHz, maintaining methane gas pressure at 15-18 Pa, methane and hydrogen pressure ratio at 1:1-1:3 and hardness of 23-35 GPa.
