【Abstract】 DDP-coated Sn nanoparticles were prepared by ultrasonic irradiation method. The nanoparticles were found to be well dispersed and coated with the surfactant DDP. The tetragonal phase of the as-prepared nanoparticles was characterized by selected area electron diffraction (SAED) and X-ray diffraction (XRD). In addition, the powder was found to have an excellent antiwear property by tribological test.更多还原
