Investigation of Tribological Properties of Oleic Acid-modified RGO-based Engine Oil Nano Fluid
Seenaa Rumh Kadhim, Hayder Jabbar Kadhim, Adil Kadhim Shakir
Abstract
In this study, reduced graphene oxide was synthesized using hydrothermal method. After reducing the graphene oxide, oleic acid was added to the reduced graphene oxide solution in order to increase the solubility and dispersion of RGO in oil. Final, RGO/GO was mixed with engine oil. Structural and morphological properties of GO, RGO and OL-RGO were studied by TEM, FTIR, PL, XRD analysis. Investigation the friction force for rotating the pin‐on‐disk shows that the lowest friction force is related to the addition of graphene oxide at a concentration of 0.01 mg / ml.
