The invention relates to a method for
anodizing the surface of a high
corrosion-resistant aluminum profile. The method particularly comprises four steps of
degreasing, oxidation, modification and
electroplating, specifically, an
anodizing solution is a
mixed solution of
pyruvic acid,
sulfuric acid, ANODAL EE solution additive,
dipotassium hydrogen phosphate,
monopotassium phosphate, aluminum
sulfate, artificial
plasma and deionized water. According to the
anodizing method, firstly, the surface of the aluminum
alloy is degreased by using a degreaser, an
oxide film on the surface is removed by
dilute acid, then the surface of the aluminum
alloy is oxidized to form an
oxide film by means of the matching of
anodic oxidation and cathodic
electroplating, and a high
corrosion-resistant
chromium film is electroplated on the outer layer of the
oxide film, so that the
corrosion-resistant performance of the surface of the aluminum
alloy is remarkably improved, and the surface of the aluminum alloy is modified; and compared with a common
anodic oxidation process, the oxide film is higher in
hardness, more resistant to
scratching,
impact and abrasion, higher in corrosion resistance, and capableof improving customer experience value, and the method has excellent practicability and creativity, high market value and wide application prospects.
