Abstract: In this paper, we reported, for the first time, a novel and simple solution method for preparing stearic acid (SA) modified Bi nanoparticles from bulk bismuth granules. The SA-Bi nanoparticles with an average size of 60nm were characterized by TEM, XRD and other techniques. The results show that SA-Bi nanoparticles have the same crystalline structure as that of bulk bismuth and exhibit good oil solubility. The tribological properties of SA-Bi nanoparticles as a additive in oil were evaluated on a four-ball tester. The tribological results show that the SA-Bi nanoparticles have good antiwear performance. In addition, the mechanism for formation of SA-Bi nanoparticles was discussed.
