PbSe nanoparticles have been prepared by solvothermal method using lead acetate with selenium source in polyvinyl pyrrolidone (PVP) and ethylene glycol medium. The morphology and crystal structure of obtaining black crystalline products were characterized by powder X-ray diffraction (XRD), energy dispersive spectroscopy (EDS) and scanning electron microscopy (SEM). The XRD pattern of the sample can be readily indexed as PbSe. The tribological properties of PbSe as additives in base oil were investigated using a UMT-2 ball-on-disc tribotester. Under the determinate conditions, the friction coefficient of the base oil containing 1.0 wt. % PbSe was lower than that of the base oil. A stable tribofilm on the rubbing surface could explain the improved tribological properties of PbSe as additives.
