Abstract

Ni-CeO2 nanocomposite coatings were prepared by pulse electrodeposition method in an ultrasonic field. The CeO2 content in the Ni-CeO2 nanocomposite coatings and surface morphology of the nanocomposite coatings were examined. The corrosion resistance of Ni-CeO2 nanocomposite coatings in 10% HCl solution was studied using static immersion method. Effects of the pulse parameters by electrodeposition with ultrasound on the corrosion resistance of Ni-CeO2 nanocomposite coatings were analyzed. The results show that the pulse parameters and ultrasound conditions obviously influence the CeO2 content in coatings and the microstructure of the nanocomposite coatings. Moderate pulse parameters can increase the CeO2 content in the coatings and refine grains, while ultrasound can make the grains finer. The corrosion resistance of the Ni-CeO2 nanocomposite coatings is related to the CeO2 content in coatings, grain size and compact microstructure of the coatings. The best corrosion resistance for the Ni-CeO2 nanocomposite coating is obtained under the condition of 0.2 duty cycle and 1000Hz pulse frequency in the presence of ultrasound, where Ni-CeO2 nanocomposite coating has higher CeO2 content, finer grains and more compact microstructure.
