Abstract
The purpose of this paper was to investigate the tribological properties of carbon materials with various morphologies ie graphene oxide GO and carbon spheres CSs utilized as lubricating additives on a ball–plate tribotester The morphology and spectroscopy characterization of GO and CSs were investigated by scanning electron microscopy transmission electron microscopy Fourier transform infrared spectrometry and thermogravimetric analysis Friction and wear properties of the sunflower seed oil filled with GO and CSs were investigated by using a MST3000 ballondisk apparatus Results show that the sunflower seed oil containing 03 wt GO nanosheets exhibited a substantial diminution in friction and wear compared with the 30 wt CSs as sunflower seed oil additives Formation of lowshear strength tribofilms containing GO and its selflubricating behavior was the key factor in reduction of the friction and prevention from wear and deformation In addition friction mechanism of CSs was also discussed
