Abstract: The cyclic voltammetry and potential-time curve at current step were used to investigate the electroreduction of Ni(Ⅱ), Ti(Ⅳ) in the urea-NaBr-KBr melt. The electroreduction of Ni(Ⅱ) to nickel is irreversible in one step. The transfer coefficient and the exchange current density of the reaction Ni(Ⅱ)+2e =Ni were determined as 0.4 and 1.1×10-6A·cm-2 at 100℃. The Ti(Ⅳ) was reduced to Ti(Ⅲ) and formed alloy with Ni on cathode in urea-NaBr-KBr-NiCl2-TiCl4 melt. The content of Ti in the Ti-Ni alloy changed with the cathode potential and reached 59% (in mole).
