Preparation of Ni-Nd₂O₃ Nanocomposite Coatings by Electrodeposition under Dual-Frequency Ultrasound

Abstract:

The Ni-Nd₂O₃ nanocomposite coatings were prepared by electrodeposition under dual-frequency ultrasound(DU). The Nd₂O₃ content and surface morphology of Ni-Nd₂O₃ nanocomposite coatings were analyzed by scanning electron microscopy (SEM). The results showed that the Nd₂O₃ content of the nanocomposite coating prepared by electrodeposition using DU was high at 3.48% and the surface morphologies of DU nanocomposite coating showed better smooth surface, finer grain and more compact microstructure. A kind of method to prepare high quality Ni-Nd₂O₃ nanocomposite coating was obtained, which was: 40 g/L Nd₂O₃ nanoparticles, 45°C the temperature of electrolyte, 4A/dm² cathode current density, 240W the power of bath-type ultrasound(BU), 100kHz the frequency of BU, 30W the power of probe-type ultrasound(PU), 20kHz the frequency of PU, and 1000r/min the stirring speed.
