چکیده
To investigate the synergistic effect of oleic acid modification and dispersant on dispersion stability wear resistance graphene in base oil. Modified was prepared by using as surface modifier T161 dispersant. The microstructure characterized SEM Raman. effects were investigated, optimal addition amount determined. At same time, optimum modified determined MMU–10 testing machine. And feasibility finished lubricating oil studied. also results showed that with level 0.5wt% had best modification, there no obvious precipitation after standing for one week. sample 0.075wt% +0.5%T161 anti-wear a friction coefficient 0.52. Compared oil, is increased 26.9%. analysis could greatly improve Graphene added lubrication mechanism particles to fill pits presence adsorption film. will not antiwear antifriction destroys original

Lubricating Oil Additives
1.1 Lubrication (Rizvi, 2009) The principle of supporting a sliding load on a friction reducing film is known as lubrication (Ludema, 1996). The substance of which the film is composed is a lubricant, and to apply it is to lubricate. These are not new concepts, nor, in their essence, particularly involved ones. Farmers lubricated the axles of their ox carts with animal fat centuries ago. But mo...
