The aim of this work was the further experimental verification of the existence of the phenomenon of electrochemical phase formation in metals and alloys via a supercooled liquid state stage. Assuming that the phase formation in electrodeposition of metals involves occurrence of some deeply supercooled metallic liquid and its subsequent ultrarapid solidification, it was suggested that quasicrystals may be present in deposit layers next to the cathode. A further suggestion was that such electrochemical phase formation via metal's supercooled liquid state must present a possibility to produce electrodeposits in the form of phases with completely quasicrystalline structure. It was found that the phenomenon under study here is proved by the following experimental facts: (1) occurrence of quasicrystals in electrodeposit layers next to the cathode, a behaviour similar to that in interface-near metal layers at crucible walls in ultrarapid solidification of a deeply supercooled melt; and (2) electrochemical phase formation in metals resulting in phases with quasicrystalline structure when formation of a periodically ordered crystal structure is hindered in the course of deposition.
