“…The recycling of aluminum metal matrix composite via electrolysis in the same ionic liquid was examined at 103 • C. Pure aluminum was deposited on a copper electrode. The deposit microstructure ranged from columnar to spherical one [80]. The electrodeposition of Al in three different water-and air-stable ionic liquids, [BMP]Tf 2 N, [EMIM]Tf 2 N and trihexyl-tetradecylphosphoniumbis(trifluoromethylsulfonyl)imide (P 14,6,6,6 Tf 2 N), was studied.…”

“…We can conclude that the kinetics of Ti-Al alloy deposition is a quasi-reversible process for AlCl 3 -BmimCl electrolyte and was reported by other investigator. [25] Region B defines a steady state for a short period of 10 to 15 minutes. The decreasing rate in current density is due to the effect of both activation and concentration polarization.…”

“…[17][18][19][20][21] Recently, Reddy et al [22][23][24][25] investigated the electrorefining of aluminum alloy in 1-butyl-3-methyl imidazolium chloride (BmimCl) and the production of high-purity aluminum deposit from AlCl 3 -BmimCl melt at 100°C ± 3°C. Karpinski et al [26] studied the finding that, when BmimCl is present in molar excess over AlCl 3 , i.e., (AlCl 3 : BmimCl) < 1.0, the ionic liquid becomes basic and melt contains only AlCl 4 À anions.…”

Application of novel low-temperature ionic liquid electrolytes for the extraction of Ti-Al alloys was investigated. The study was focused on the production of Ti-Al alloys from AlCl 3 -1-butyl-3-methyl imidazolium chloride (BmimCl) (molar ratio of AlCl 3 and BmimCl is 2:1) at different temperatures between 70°C and 125°C ± 3°C. The Ti-Al alloys were deposited on titanium sheet (>99.9 wt pct) cathodes at various voltages between 1.5 and 3.0 V. Titanium sheet was used as the anode and its dissolution served the source of Ti ion in the electrolyte. Morphology and composition of deposited Ti-Al alloys were investigated using a scanning electron microscope (SEM) with energy-dispersive spectroscopy (EDS) and an inductively coupled plasmaoptical emission spectrometer (ICP-OES). The phase analysis was carried out using X-ray diffraction (XRD). This study was focused to determine the effect of process variables such as applied voltage and temperature on cathode current density, current efficiency, composition, and morphology of Ti-Al alloys. The Ti-Al alloys containing about 13 to 25 atom pct Ti were produced with a current efficiency of about 79 to 87 pct. This study shows that uniform and fine particle size with high titanium content Ti-Al alloy was obtained in the voltage range of 1.5 to 2.0 V and temperature between 70°C to 100°C.

“…[1] Therefore, recycling of this type of scrap composites has become an important technological and environmental issue. Recycling of SiC-reinforced Al-matrix composites has been reported to be possible by five different technologies: (1) by simple remelting, [2,3] (2) by filtration of the liquid composites, [4] (3) by electromagnetic separation, [5] (4) by electrochemical separation, [6] and (5) by flux treatment. [7][8][9][10] The latter technique will be addressed in more detail in the present article.…”
