摘要：
A method for electroplating aluminum metal on a magnesium alloy includes providing an Lewis acidic ionic liquid having dissolved species of an aluminum metal salt; pre-treating a surface of the magnesium alloy including subjecting the surface of the magnesium alloy to a reverse current etching in the ionic liquid; electroplating the aluminum metal on the surface using the ionic liquid as the electrolyte; and subjecting the surface of the magnesium alloy to a post-treatment including neutralization rinsing in a rinsing solvent solution.
