Study on the anti-wear and anti-friction properties of graphene and boron magnetic rare earth complexity

Abstract

Using graphene and boron magnetic rare earth lubricating oil additive, different mass fraction of graphene boron magnetic rare earth lubricating oil samples were configured with, anti-wear anti-friction effects were tested with different mass fraction of graphene boron magnetic rare earth samples in the four-ball test machine experiment. The experimental results show that the graphene materials used in this paper are multi- layered and have some impurities and defects. Adding a small amount of graphene to the base oil the lubricationcan be significantly improved, and in the sample range, the best quality score of graphene used with dispersant is 0.03%. Graphene and boron magnetic rare earth (T2012) oil additives have a good synergistic effect.
