CHUNG, P.P. ... et al., 2008. Electrodeposition of zinc-manganese alloy coatings from ionic liquid electrolytes. Transactions of the Institute of Metal Finishing, 86 (4), pp. 211-219
Electrodeposited zinc-manganese alloys have been found to have potentially
attractive corrosion resisting characteristics for ferrous substrates. However,
researchers have found their formation problematic from aqueous
electrolytes, due particularly to the reactive nature of manganese and its low
reduction potentials. The present investigations examine the possibility of
electrodepositing this alloy utilising an ionic liquid electrolyte. In this manner
electrolytes based upon manganese and zinc chlorides and boric acid were
made by dissolution in a 2:1 molar ratio urea: choline chloride solvent.
Physical measurements of electrolyte characteristics as well as pertinent
electrochemical information on alloy electrodeposition were obtained to
examine the efficacy of this metal/electrolyte combination.
