Cathode Process in the Electrolytic Codeposition of Titanium Diboride in Molten Fluoride

The mechanism of the electrochemical reduction of Ti(Ⅳ) and B(Ⅲ) as well as the electrochemical synthesis of TiB₂ on platinum and molybdenum electrode in molten Li-NaF-K₂TiF₆-KBF₄ system has been investigated for the first time by. Means of cyclic voltammetry. The electrodeposited coating has been analysed by X-ray diffraction. The results show that the electrolytic codeposition of titanium and boron with the formation of TiB₂ can be achieved at molar ratios B/Ti>2.
