Abstract
The effects of metal ions such as Mg2+, Li+, Na+ and K+ on the cathodic cur rent efficiency, deposit morphology, crystallographic orientation and polar ization behaviour during nickel deposition on stainless steel from aqueous sulfate solutions containing boric acid were investigated. There was virtua lly no change in current efficiency in presence of these metal ions, but ch anges were observed in the deposit morphologies and crystal orientations ev en though all the deposits looked bright, smooth and coherent. Changes were also observed in the polarization behaviour during nickel electrocrystalli zation in presence and absence of boric acid. An attempt has been made to c orrelate the effect of these metal ions on various parameters studied.
