Abstract
Nickel electrodeposits were formed directly on to AA 1100 aluminium alloy using a simple chemical pretreatment both by direct current plating (DCP) and pulsed current deposition (PCD) methods in the absence and presence of a-picoline and quinoline. In dc plating the current density was varied between 1 and 4 A dm22. In pulse plating, the current density was varied between 1 and 4 A dm22 and the duty cycle was varied between 10 and 80% at the frequency of 100 Hz. The throwing power and current efficiency of the bath were determined. The influence of current density, duty cycle, a-picoline and quinoline on throwing power and current efficiency of the bath during direct and pulse current plating have also been studied.
