The effect of ultrasonic vibration on microhardness, residual stresses and surface finish of nickel electrodeposits was investigated. A comparison was made between the results obtained with an ultrasonically agitated bath and those with a still bath. Ultrasonic agitation increased the deposition rate and limited current density. The deposit from the bath with ultrasound gave a smoother surface and exhibited increased microhardness. The residual stresses of the deposits were reduced with an ultrasonically agitated bath.
