Abstract

This work studies the direct electrochemical preparation of Ti-Fe alloys through molten oxide electrolysis (MOE) at a liquid iron cathode. Cyclic voltammetry and potentiostatic electrolysis have been employed to study the cathodic process of titanium ions. The results show that cathodic behavior happens during the negative sweep at a potential range from -0.80 to -1.25 V (vs. QRE-Mo), corresponding to the electro-reduction of titanium ions. Importantly, Ti-Fe and titanium-rich Ti-Fe alloys have been successfully produced by galvanostatic electrolysis at different current densities of 0.15 and 0.30 A cm^-2, respectively. The results show that it is feasible to directly prepare Ti-Fe alloys by the MOE method at a liquid iron cathode.
