“…Niobium-aluminum alloys were formed in the LiCl-KCl eutectic melt at tungsten and niobium electrodes. This melt was suitable for the electrowinning of Nb-Al alloys [162]. Al-Mn amorphous plating layers were electrodeposited in AlCl 3 -NaCl-MnCl 2 .…”

“…The literature reports aluminium deposition results in molten chloride media, only on an inert cathode: Mohamedi et al [11], Chryssoulakis et al [12], Bouteillon and Marguier [13] agree that AlCl 3 is reduced to Al metal in chloride media in a single step with three electrons exchanged. Similar behaviour is reported by other authors in chloroaluminate baths [14,15].…”

“…Some of those works [12,[19][20][21][22][23][24] describe alloys being formed from cathode substrate and Nb deposited. However, there are only a few works [11,22,23,25,26] describing Al and Nb co-deposition that results in Nb-Al alloy formation and those are on W, Cu and Nb cathodes, but not on vitreous carbon.…”

Niobium and aluminium were electrodeposited at 200 °C under argon atmosphere onto vitreous carbon from inorganic chloroaluminate melts (AlCl 3 +NaCl) with added niobium. Niobium was introduced into the electrolyte by anodic dissolution of metallic niobium or by chemical dissolution of Nb 2 O 5 in a melt of equimolar AlCl 3 +NaCl mixture. The processes of deposition/dissolution onto/from vitreous carbon were investigated by cyclic voltammetry and chronoamperometry. Characterization of the obtained deposits was done by Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). The only observed reduction processes on the working electrode in the potential window from 1.000 V to -1.000 V vs. Al, were individual niobium deposition and codeposition of niobium and aluminium with Al-Nb alloys formation.Electrodeposition of niobium from the chloroaluminate melt with added niobium (V) oxide seems to start at around -0.100 V vs. Al and at about -0.200 V vs. Al aluminium starts codepositing. During the codeposition Nb-Al alloys were formed. Niobium deposition starting potential from the electrolyte with niobium added by anodic dissolution starts at 0.100 V vs. Al, and aluminium codeposition starting potential was at around -0.025 V vs. Al, followed by Nb/Al alloy formation.
