| description | Graphene loaded ferric oxide (G/Fe<sub>3</sub>O<sub>4</sub>) composites were prepared by chemical modification using graphene and nano-Fe<sub>3</sub>O<sub>4</sub> as raw materials. The composites were characterized by transmission electron microscope, X-ray diffractometer and Fourier infrared spectrometer, and G/Fe<sub>3</sub>O<sub>4</sub> composites were added to SN 5W-30 lubricating oil, and the dispersion stability and tribological properties of composites in lubricating oil were studied by plasma spectrometer and four ball friction tester. The results show that G/Fe<sub>3</sub>O<sub>4</sub> composite materials generated by the co-modification of oleic acid and silane coupling KH570 are better dispersed on the graphene surface than with oleic acid modification alone; precipitation stability experiments show 10 days later,iron content in the lubricating oil is decreased by 48.3% without composite added,iron content is decreased by 39% with oleic acid modified composite added, and iron content is decreased by 31.1% with oleic acid and KH570 jointly modified composite; four-ball experiments show that G/Fe<sub>3</sub>O<sub>4</sub> composites acting as lubricating oil additives have good tribological properties, the use of oleic acid and KH570 joint modification effect is better than the use of oleic acid modification, the maximum card-free bite load <i>P</i><sub>B</sub> is increased by 6.5%, the diameter of the mocha is decreased by 4.4% and the coefficient of friction is decreased by 4.8%. |
