Characteristics Of Titanium Electrodeposited By Potential Pulse Method In Molten-Salts

Titanium deposits were prepared on nickel substrate by potential pulse method in molten LiCl-NaCl-KCl eutectic salts with 2 mol% K2TiF6. The influence of the electrolysis conditions on crystal orientation and morphology of the deposits was investigated by X-ray diffraction and scanning electron microscopy, respectively. The preferred crystal orientation of (110) of titanium deposits increased as temperature increases, and the crystal orientation of the deposits varied also with potential and pulse shape during electrolysis. The morphology of titanium deposits showed well-crystallized grains, which became larger with increase of temperature. The change in crystal orientation of the deposits was tried to be explained by the absorption inhibition model.
