    • Excellent corrosion resistance and paint adherence and low surface electrical resistance can be imparted to magnesium alloys that have been molded by, for example, die casting or thixomolding, by first etching the surface with an acidic aqueous solution having a pH of 1 through 5 and preferably containing a carboxylic acid and then desmutting the resulting surface by contact with an alkaline aqueous solution that has a pH of 7 through 14 and contains an organophosphorus compound. Prior to this etching, the magnesium alloy surface is preferably degreased using an alkaline aqueous solution containing inorganic salt and surfactant or using an acidic aqueous solution containing acid and surfactant. The corrosion resistance and paint adhesion may be further increased by forming a conversion coating over the surface produced by desmutting.
