The cyclic voltammetry and potentialtime curve at current step were used to investigate the electroreduction of Ni(Ⅱ), Ti(Ⅳ) in the ureaNaBrKBr 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 ureaNaBrKBrNiCl_2TiCl_4 melt. The content of Ti in the TiNi alloy changed with the cathode potential and reached 59% (in mole).
