Niobium and aluminium have been electrodeposited from inorganic chloroaluminate melts onto gold substrate at 473 K. The melts were prepared from an equimolar mixture of AlCl3+NaCl with niobium added by anodic dissolution. It was found that aluminium and niobium underpotential deposition on gold precedes overpotential deposition of niobium and subsequent aluminium deposition. Niobium was overpotentially deposited individually and co-deposited with aluminium. Applied electrochemical techniques (linear sweep voltammetry, polarization, open circuit and potential step) indicated, then physical analytical methods (scanning electron microscopy, energy dispersive spectrometry, atomic force microscopy and X-ray diffraction) confirmed formation of several niobium-aluminium, niobiumgold and aluminium- gold alloys in niobium and aluminium underpotential as well as in niobium and aluminium overpotential regions.
