Abstract: Electrodeposited zinc alloys have long been recognised as effective barrier and sacrificial coatings for ferrous substrates. The effect of alloying zinc with, in the main, more noble metals, has produced finishes of higher corrosion resistance than simply electrodeposited zinc. In this manner zinc alloys such as zinc-nickel, zinc-cobalt and zinc-iron are routinely electrodeposited on an industrial scale. A further zinc alloy, zinc-manganese, has shown a high level of promise in terms of corrosion resistance but is difficult to electrodeposit from conventional aqueous solutions. The present investigations are centred around examining the formation of zinc alloys, by electrodeposition, from non-aqueous ionic liquids. These electrolytes are essentially molten salts which maintain their liquid state at, or near, to room temperature. Being non-aqueous they are unlikely to promote significant hydrogen evolution from active metal surfaces - a severe problem for the electrodeposition of zinc-manganese alloys from aqueous electrolytes. Electrodeposition conditions for the latter will be discussed in terms of electrolyte types, current density and solution characteristics such as agitation type and temperature. Zinc-manganese alloy electrodeposits will be characterised in terms of their composition and morphology. Finally corrosion resistance data will be presented and this will be compared with other more conventionally deposited zinc alloys.
