摘要：
A simple and rapid process has been developed for the preparation of indium nanoparticles from bulk indium via ultrasound irradiation. Transmission electron microscopy (TEM) shows the as-prepared indium nanoparticles are appear to be close to a spherical shape. X-ray diffraction (XRD) pattern indicates that the samples are the tetragonal phase of indium with the same crystal structure as that of the bulk indium. It is confirmed by X-ray photoelectron spectrum (XPS) analysis that there is an indium oxide layer at the surface of the indium nanoparticles. The tribological property of indium nanoparticles as additives in oil is evaluated on a four-ball tester and shown that indium nanoparticles exhibit good performance in wears. (c) 2005 Elsevier B.V.
