NOVELTY - Magnesium alloy surface anticorrosive coating comprises 83-90 wt.% aluminum powder, 9.5-15 wt.% aluminum oxide powder, and 0.5-2 wt.% graphene oxide powder. The coating is prepared by coupling graphene oxide with a part of aluminum powder to obtain graphene oxide-coated aluminum composite powder, uniformly mixing remaining aluminum powder and aluminum oxide powder with graphene oxide coated aluminum composite, and cold-spraying on the surface of the magnesium alloy. USE - The method for preparing magnesium alloy surface composite anti-corrosion coating is useful in the field of automobile, aerospace and weapon equipment. ADVANTAGE - The magnesium alloy surface composite anti-corrosion coating has high hardness, good stability, excellent corrosion resistance of oxidation graphene comprehensive coating phase function and characteristics, and can reach excellent anticorrosion effect to the magnesium alloy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparing the magnesium alloy surface anticorrosive coating.
