Abstract

Abstract: A sonochemical method for the direct controlled synthesis of Cd-Bi nanoparticles from a bulk Cd-Bi alloy is introduced.The nanoparticles were found to be monodispersed and the size distribution can be easily controlled by adjusting the ultrasonic power.The formation and the constituent of the as-prepared Cd-Bi nanoparticles were revealed by means of X-ray diffraction, differential thermal analysis and thermogravimetry, transmission electron microscopy, and electron diffraction.It was found that the Cd-Bi eutectic alloy nanoparticles are made of the hexagonal phase of metal cadmium and the rhombohedral phase of metal bismuth.In addition, we also found through tribological tests that the powder has an excellent antiwear property.

Key words: Sonochemistry, Nanoalloy, Controlling fabrication, Tribology
