Abstract
Using an ultrasonic field frequency of 20 kc/s and field intensities from 0 to 1·2 W/cm2, the influence of ultrasonic vibrations on the electrodeposition of gold from a bright gold cyanide bath was studied at 28°C, with reference to the brightness, microhardness, porosity and structure of the deposit at various current densities. It was found that ultrasonic vibrations confer an increase in brightness, and increase the permissible current density and the current efficiency; the microhardness of the deposit is unproved and its structure is changed. At an ultrasonic field intensity of 0·8 W/cm2, the permissible current density is raised to 1·8 A/dm2 and a deposition rate of 54 μ/h is achieved.Keywords
