Electrodeposition of Al-Ti alloys from aluminum chloride-N-(n-butyl)pyridinium chloride room temperature molten salt

Electrodeposition of aluminum-titanium alloys has been carried out onto platinum and mild steel cathodes from 6.14:3.07:0.09 (mole ratio) AlCl 3 -BPC-TiCl 4 molten bath by controlled-potential and pulse potential methods. High concentration of TiCl 4 (>0.1 mol dm - 3 ) interferes with the deposition processes of Al and Al-Ti alloys. The deposition of pure titanium from this electrolyte is difficult, but titanium is co-deposited with aluminum in the form of alloys. The morphologies of the electrodeposited layers have been investigated by X-ray diffractometer and scanning electron microscope. The cathodic current efficiency for the deposition of alloys is about 97%.
