In this paper, we reported a facile and rapid process to prepare tin nanoparticles from bulk tin via ultrasound dispersion. The morphology and structure of synthesized tin nanoparticles were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectrum (XPS) and thermogravimetric analysis (TGA). The results show that the morphology of tin nanoparticles is spherical and the structure of tin nanoparticles has the same crystal structure as the bulk tin. In addition, the tribological property of tin nanoparticles as additives in oil is evaluated on a four-ball tester and the results show that tin nanoparticles exhibit good performance in wear.
在本文中，我们报道了一种通过超声分散从块状锡制备锡纳米颗粒的简便快速方法。采用透射电子显微镜（TEM）、X射线衍射（XRD）、X射线光电子能谱（XPS）和热重分析（TGA）对合成的锡纳米颗粒的形貌和结构进行了表征。结果表明，锡纳米颗粒的形貌为球形，且其结构与块状锡具有相同的晶体结构。此外，在四球试验机上评估了锡纳米颗粒作为油中添加剂的摩擦学性能，结果表明锡纳米颗粒在磨损方面表现出良好的性能。
