Nanocrystalline materials have gained considerable attention, especially du
ring the last decade. In this context, this paper reviews the work done in
this period, paying specific attention to nanocrystalline nickel, prepared
by electrodeposition D.C, as well as pulse plating have been dealt with in
detail and the suitable parameters have been discussed. It also discusses t
he structure of the deposit and its improved properties, with special focus
on corrosion resistance, micro-hardness, adhesion, etc. A few current indu
strial applications are also discussed.
