Abstract
Nickel and manganese were codeposited from acidic chloride-sulfate solution in the presence and without sodium gluconate as complexing and buffering agent. Equilibrium pH-dependent distribution of soluble species in the baths was calculated. Deposition of metals was studied by cyclic voltammetry and Hull cell tests. Deposits were obtained in potentiostatic (−1.6 to −1.7 V vs. Ag/AgCl) and galvanostatic (4–8 A/dm2) conditions. It was found that the buffering action of gluconate ions improved the quality of the deposits, and compact Ni-Mn with a grid of fine crack layers was produced. The additive inhibited the formation of nonmetallic inclusions represented by decreased oxygen content in the deposits. Layers produced at constant potentials contained 67–79 % Ni, 1–8 % Mn, and 15–30 % O. Under galvanostatic conditions, the average compositions were in the range of 18–80 % Ni, 2–48 % Mn, and 17–42 % O. Despite of the bath composition, the main cathodic reaction was hydrogen evolution resulting in very low amounts of the cathodic deposits.
