Abstract
Electrochemical impedance spectroscopic (AC impedance) studies have be en carried out on nickel electrodeposits obtained from still and ultra sonically agitated Watts electrolytic bath. The samples have been test ed in 3.5% sodium chloride solution. The beginning of corrosion proces s is well defined by the appearance of semicircle. The variation of cu rrent density (ed) during plating influences the performance of the co ating. Ultrasonic agitation has improved the corrosion resistance prop erties of nickel deposits.
