Effect of Ultrasound Power on Ni-Nd₂O₃ Nanocomposite Coatings Prepared by Electrodeposition in Combination Ultrasonic Field

Abstract

The Ni-Nd2O3 nanocomposite coatings were prepared by electrodeposition under combination ultrasound field. The Nd2O3 content and surface morphology of coatings were analyzed by scanning electron microscopy (SEM). And the microhardness of coatings was tested. The results showed that ultrasound power is a great influence on Nd2O3 content in coatings. The Nd2O3 content of the nanocomposite coating prepared by electrodeposition using combination ultrasound was high at 3.48%, when bath-type ultrasound power was 240W and probe-type ultrasound power was 30W. And the surface morphologies of nanocomposite coating showed better smooth surface, finer grain and more compact microstructure.
