| Abstract: In the presence of stearic acid, the surface modified Pb-Sn alloy nanoparticles were prepared through the liquid phase dispersion method in liquid paraffin. The morphologies and structures of the material were characterized by TEM, XRD, DTA and TG. The results indicate that the samples have an average diameter of 20 nm, with Pb-Sn structure and oxide shell, and have at least 12% organic covered layer. The tribology test indicates that, when the concentration of Pb-Sn alloy nanoparticles as additives in lubricating oil is between 0.25%～0.75%, the improved tribological properties are achieved. |
