Abstract
A method of making a magnesium alloy housing includes steps as follows: providing a magnesium alloy base; submerging the magnesium alloy base in a phosphate solution, thereby forming a chemical plating layer on the surface thereof; coating a prime coating on the chemical plating layer and drying the prime coating, thereby forming a prime layer; coating an enamel on the prime layer and drying the enamel, thereby forming a color coating layer; grinding the color coating layer with a grinding wheel, thereby forming a hair line layer; coating a metallic coating on the hair line layer and drying the metallic coating, thereby forming a decorative layer; and coating a transparent coat on the decorative layer and drying the transparent coat, thereby forming a transparent protecting layer.
