▎ 摘  要

NOVELTY - Improving corrosion resistance of magnesium alloy by using nitrogen-doped graphene quantum dot coating comprises taking graphene quantum solution as electrolyte solution, and three-electrode system, magnesium alloy as working electrode, and saturated potassium chloride/calomel electrode as reference electrode, the platinum electrode is auxiliary electrode, and electrochemically depositing the nitrogen-doped graphene quantum dots on the surface of the magnesium alloy, then placing the deposited nitrogen-doped graphene quantum dot coating in the silylation solution, the temperature of the silylation treatment is 40-55 degrees C, carrying out silylation for 1-2 hours, and drying the silanized magnesium alloy to obtain nitrogen-doped graphene quantum dot coating on the surface of the magnesium alloy. USE - The method is useful for improving corrosion resistance of magnesium alloy by using nitrogen-doped graphene quantum dot coating. ADVANTAGE - The nitrogen-doped graphene quantum dot coating on the surface of the magnesium alloy has high density.
