Abstract

The present invention relates to a surface treatment method of a magnesium alloy for a smartphone exterior material, which can enhance film formation, stabilization and corrosion resistance of the magnesium alloy. The surface treatment method of magnesium alloy for a smartphone exterior material comprises: a washing step of washing impurities of the surface of a magnesium alloy for a smartphone exterior material using acid solution or alkaline solution; a preprocessing step of widening a specific surface area of the washed magnesium alloy for the smartphone exterior material using sand blast; an anodizing step of anodizing the preprocessed magnesium alloy for the smartphone exterior material to form a film; and a postprocessing step of washing and drying the anodized magnesium alloy for the smartphone exterior material using distilled water.
