Abstract

The metalliding of nickel with niobium was carried out by electrolysis in moten fluorides in the temperature range 850 to 1050° C. Several alloy layers were prepared and analysed. The composition of the bulk of the layer corresponds to the NbNi3 compound but it is assumed that during the metalliding process a thin layer of NbNi is formed at the surface of the electrode. Electrochemical measurements were related to the kinetics of layer growth; these allowed the determination of the diffusion coefficient and the Arrhenius linear relationship of this parameter with the temperature.
