Abstract
The discharge process of Nb(IV) complexes to Nb was studied by cyclic voltammetry. A galvanostatic electrolysis with the cathodic current density of 1.5·10-2 A cm-2 in the NaCl-KCl-NaF-K2NbF7 melt in contact with Nb was used for deposition of niobium coatings at temperature 1023 K, and time of process from 8 to 12 hours. The coatings were continuous and smooth due to the special design of the cathode. The rotation speed of the stirrer in all experiments did not change and was chosen equal to 35 rpm. Such conditions made it possible to obtain coatings with the thickness up to 150 μm. The main characteristics of the niobium coatings such as purity, roughness, nonsphericity and superconductivity were investigated.
