Electroforming Technology of Ni-CeO₂ Nanocomposites Using Rotating Cylindrical Cathode in Ultrasonic Field

Abstract:

Ni-CeO₂ nanocomposites were electrodeposited using rotating cylindrical cathode in ultrasonic field. The surface morphologies and the CeO₂ contents in the nanocomposite were examined by the Scanning Electron Microscopy and the Energy Disperse Spectroscopy. The microhardness of nanocomposites were also evaluated by digital microscopical Weis Sclerometer. The effect of ultrasonic power and cathode rotating speed on the CeO₂ nanoparticles contents and the distribution condition of the nanocomposites were investigated. The results indicate that both the ultrasonic power and cathode rotating speed effect the microstructure and property of the nanocomposites remarkably. Prepared under the technology parameters of cathode current density 4A/dm², cathode rotating speed 1200rpm, CeO₂ nanoparticles addition 40g/L and ultrasonic power 300W, the Ni-CeO₂ nanocomposites present refined crystal grains, compact microstructure, smooth surface morphology and high microhardness.
