Electrodeposition of Al on Magnesium Alloy from Aluminum Chloride/1-ethyl-3-methylimidazolium Chloride Ionic Liquids

A continuous and adhesive Al layer was successfully electrodeposited on a Mg alloy in aluminum chloride/1-ethyl-3-methylimidazolium ionic liquid at room temperature. Surface morphology, crystal Structure, and chemical composition of the deposit were examined with a scanning electron microscope, an X-ray diffractometer, and an X-ray energy dispersive spectroscope, respectively. The corrosion resistance of the M-coated Mg alloy was also evaluated.
