✦ Synopsis

Wear rates of nickel electrodeposits obtained from a conventional Watts bath were studied. A comparison was made between the wear rates of nickel electrodeposits obtained with an ultrasonically agitated bath and those obtained with a still bath. Deposition was done on mild steel, and wear rates were measured for unlubricated rubbing against a rotating hardened steel disc. The wear loss of the deposits obtained with the ultrasonic bath was lower than that with the still bath. When ultrasonic waves are passed through the electrolyte solution, bubbles are formed which grow and collapse due to continuous absorption of energy from alternating compression and expansion cycles of the sound waves.
