    This paper used graphite nanoparticles with the diameter of 35 and 80 nm and LB2000 vegetable based oil to prepare graphite\noil-based nanofluids with different volume fractions by two-step method. The tribological properties of graphite nanoparticles as\nLB2000 vegetable based oil additive were investigated with a pin-on-disk friction and wear tester. Field emission scanning electron\nmicroscope (FE-SEM) and energy dispersive spectroscopy (EDS) were used to examine the morphology and the content of some\ntypical elements of wear scar, respectively. Further, the lubrication mechanism of graphite nanoparticles was explored. It was found\nthat graphite nanoparticles as vegetable based oil additive could remarkably improve friction-reducing and antiwear properties\nof pure oil. With the increase of volume fraction of graphite nanoparticles, the friction coefficient and the wear volume of disk\ndecreased. At the same volume fraction, the smaller particles, the lower friction coefficient and wear volume.The main reason for\nthe improvement in friction-reducing and antiwear properties of vegetable based oil using graphite nanoparticles was that graphite\nnanoparticles could form a physical deposition film on the friction surfaces
