Abstract: The title composite organic coatings for ZM5 magnesium alloy was prepared to improve its corrosion resistance. The pretreatment process of magnesium alloy, organic corrosion prevention coating, decorative coating and film's performance were studied. It was indicated that the organic coatings on Mg alloy could provide high corrosion resistance, and the chemical conversion film could effectively improve the adhesion and its anti-corrosion ability.
