Investigations on electrodeposition of nickel from dimethylsulfoxide

Abstract Process of cathodic deposition of nickel mainly from Ni(BF 4 ) 2 solution in DMSO has been investigated using various experimental techniques. It has been found that this process is complicated. The collected experimental data indicate that passivation of fresh cathodic layer of Ni by chemisorption of DMSO molecules takes place. By basing on the rde methods the values of α n m = 0.4 (± 0.05) and k fh = f( E c ) have been estimated.
