Abstract
The present invention discloses a method for treating magnesium alloys by chemical conversion. This method can improve corrosion resistance and paint adhesion of magnesium alloys, and produces an admirable appearance. Additionally, the method of the present invention is more environmentally friendly than conventional processes, because non-chromate chemicals are used in acid pickling and chemical conversion. Furthermore, the method of the present invention can be widely applied to the magnesium alloys manufactured by casting and rolling.
