A method of preparing a magnesium alloy substrate for an electroless electro-deposition surface treatment includes cleaning the magnesium alloy substrate in a wet solution, whereby a magnesium hydroxide layer is formed on an outer surface of the magnesium alloy substrate, and heating the magnesium alloy substrate to a temperature sufficient to convert the magnesium hydroxide layer to a magnesium oxide layer.
