HARDNESS AND STRUCTURE OF NICKEL ELECTRODEPOSITED FROM ITS CHLORIDE AND ACETATE SALTS DISSOLVED IN PURE DIMETHYSULFOXIDE.

Abstract

Earlier studies on the electrodeposition of nickel from nickel chloride or nickel borofluoride dissolved in pure dimethylsulfoxide did not lead to satisfactory results. However, nickel acetate/DMSO bath resulted in deposition but conductivity of the bath was too low. Addition of ammonium acetate improved the conductivity of the bath and quality of the deposit. As an extension of this work, deposition was studied with nickel chloride solutions in presence of varying concentration of ammonium acetate.
