摘要
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/cm2is ideal with the perfect boundary of crystal grain.
