Electrodeposition of Al on magnesium alloy from aluminum chloride/l-ethyl-3-methylimidazolium chloride ionic liquids

Abstract

A continuous and adhesive Al layer was successfully electrodeposited on a Mg alloy in aluminum chloride/1-ethyl3-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 Al-coated Mg alloy was also evaluated.
