Tribological habits of graphene oxide-Fe3O4 nanocomposites for components in water-based lubricants: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0

Summary

Graphene oxide-Fe₃O₄ (GO-Fe₃O₄) nanocomposites had been synthesized by way of the solvothermal technique and used as lubricant components. The tribological assessments and a collection of characterization strategies had been performed to know the lubrication mechanism of GO-Fe₃O₄ nanocomposite. The GO-Fe₃O₄ nanocomposites exhibited wonderful tribological properties as a result of excessive dispersion stability in water. Friction outcomes indicated that the GO-Fe₃O₄ can considerably enhance the tribological properties and the friction coefficient and put on scar diameter had been decreased by 33.6% and 32.3% in contrast with base fluid, respectively. Raman outcomes confirmed that the GO nanosheets fashioned a protecting movie on the contact interfaces, which facilitated shear, decreased the damage and inhibited the tribo-corrosion. The lubrication mechanism was attributed to the synergistic lubrication impact between the Fe₃O₄ nanospheres and the GO nanosheets.
