Abstract:An ionic liquid was prepared by mixing AlCl₃ and 1-methyl-3-ethylimidazolum bromide (EMIM)Br under dry argon atmosphere. Electrodeposition of aluminum on magnesium was conducted at 298.15 K for 1 h by the ionic liquid and the electrochemical behavior was discussed. The results show that the aluminium deposition occurs at a potential about −0.1 V. Cathode surface was analyzed by SEM, XRD and EDS. Aluminum is successfully electrodeposited on magnesium from (EMIM)Br-AlC1₃ ionic liquid, and the crystal grain quality of the deposit at 15 mA/cm² is ideal with the perfect boundary of crystal grain.

Key words: aluminum; ionic liquid; (EMIM)Br-AlC1₃; electrodeposition
