Abstract

This paper describes the beneficial effects of ultrasound in several electrochemical processes. During the electroplating of chromium from chromium (VI) solutions, the application of ultrasound has been found to be effective in controlling mist emission and improving both the efficiency of the process and the hardness of the deposit. During the electroplating of nickel, it was found that efficiency of the process and the hardness of the deposits were dependent on the applied ultrasonic frequency and power. In the case of electroless nickel plating, the effect of ultrasound was dependent on the nickel concentration. In the presence of ultrasound, the rate of removal of silver from waste photographic processing solutions was found to depend on the speed of rotation of the electrode.
