Abstract
Titanium deposits were prepared on 304 stainless steel substrates by both constant current and pulse current methods in molten KCl-NaCl-LiCl eutectic salts with 2 mol % potassium hexafluorotitanate. The influence of electrolysis conditions on the crystal orientation and morphology of the titanium deposits was investigated by using X-ray diffraction and scanning electron microscopy, respectively. It was found that the orientation index of the titanium deposits varied with temperature, electrolysis time, current density and pulse shape during electrolysis. The deposits showed a granular structure, in which the grains became larger with increase in temperature. Titanium deposits with pulse current above 873 K had a better corrosion resistance than pure titanium sheet.
