zinc-nickel electrodeposits have been widely adopted for surface treatment of automobile steel sheet for high corrosion resistance. in this work the effect of pulse parameters on the zn-ni alloy electrodeposits was investigated. the hardness, thickness, corrosion resistance and composition of deposits thus produced were investigated. the surface topography of the deposits was also observed in s...

A review on pulse and pulse reverse techniques for electrodeposition have been attempted. Pulse electrodeposition (PED) of some metals and lloys are reported. The effects of mass, transport, electrical double layer pulse parameters and current distribution on surface roughness and orphology are presented. Applications, advantages and disadvantages of PC and PRC techniques are discussed along wi...

Amorphous alloys can be electrodeposited by direct or pulsed current. According to electrocrystallization theory, a high crystallization overpotential produces microcrystalline structure in the deposits. Thus if the amorphous phase consists of microcrystals, pulsed current is preferable for preparing amorphous alloys. However, another newly proposed theory holds that the amorphous phase structu...
