Sonoelectrochemical Deposition of Functional Composite Layers

摘要

Ultrasound was applied for the electrodeposition of metal/ceramic and metal/metal composites. Ni/ceria composites were deposited from Watts and sulfamate based electrolytes containing dispersed ceria using ultrasonic irradiation for the deagglomeration of oxide particles. The electrochemical deposition of silver at the tip of an ultrasonic horn probe using pulsed ultrasound was explored for its potential to electrodeposit Ni/Ag composites. First results are presented. Sonoelectrochemical processes were in part monitored in-situ by the electrochemical quartz crystal microbalance technique. Compositions of the electrodeposits were analyzed by energy dispersive spectroscopy and in part by electron probe microanalysis.
