Abstract

The effect of ultrasound sonication on the electroplating of iridium in an aqueous hexabromoiridate(III) is examined at several different ultrasound intensities. Ultrasound sonication is effective not only in inhibiting the crack formation in iridium deposits but also in decreasing the surface roughness of iridium electrodeposits. Those effects of ultrasound sonication are attributed to the enhancement of the amount and uniformity of mass transport caused by the thinning of diffusion layer due to the agitating action of sonication.
