| Abstract Scope |
Ti-Al alloys were electrodeposited from the Lewis acidic ionic liquid (IL) containing 1-butyl-3-methylimidazolium chloride (BMIC) and aluminum chloride (AlCl3). A constant potential electrodeposition was performed in a two-electrode configuration on copper cathode for 4 h at 383 K from BMIC-AlCl3 electrolytes with different AlCl3 mole fractions and deposition potentials. Titanium was served as anode and also the source of Ti ions. Ti-Al alloys deposited on Cu substrate at different synthesis conditions were analyzed using scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray diffraction techniques. A Ti0.4Al0.6 phase with 40-atom % Ti was obtained in the final deposit at optimized parameters and was confirmed by repeating electrodeposition experiments with identical synthesis conditions. The cathode weight gain and anode weight loss was measured to determine the Faradaic current efficiency and energy consumption values of Ti-Al electrodeposition process. More work is underway to further improve the percentage of Ti in the Ti-Al deposits. |
