Abstract The process of electrolytic deposition of copper-aluminium alloys from a nonaqueous ethylbenzenetoluene bath was studied using an electrical system consisting of two independent current circuits to control cathode alloy deposition and anode copper dissolution separately. The influence of electrical parameters on current efficiency and chemical composition of the Cu-Al alloys was determined, as was the phase composition, microhardness and surface morphology. In alloys containing about 10% Al the presence of a martensiticβ′1 phase was detected. Due to the very fine-grained structure of the electrolytic alloys obtained, no shape memory effect was observed in copper microelements with Cu-10.6%A1 alloy coatings.
