Abstract
In this paper, the corrosion film of Sodium Dodecyl Sulfate (SDS) and graphene aqueous solution has been studied. The results showed that the corrosion film is a kind of graphene/Fe3O4 film, representing the positive effect of tribological performance under water lubrication. Under the protection of graphene/Fe3O4 film, the friction coefficient of steel decreases from 0.41 to 0.17, and the wear scar depth falls from 2.57 μm to 0.98 μm at load of 2 N. Graphene/Fe3O4 film exhibits excellent tribological properties under water lubrication due to three reasons. Graphene and Fe3O4 are both antifriction materials, effectively reducing the friction coefficient and wear rate under water lubrication. The hydrophilicity of graphene/Fe3O4 film is significantly improved, making graphene enter the gap between friction pairs easily. As a result, the pitting in the corroded surface can continuously collect and release the Fe3O4 and graphene. These antifriction materials can work longer. Under the synergistic effect of the above three aspects, graphene/Fe3O4 film had excellent friction reducing and anti-wear effect under water lubrication.
