Title: METHOD OF PREPAIRING ALUMINUM ALLOY RESIN COMPOSITE AND ALUMINUM ALLOY-RESIN COMPOSITE OBTAINABLE BY THE SAME
Abstract:
A method of preparing aluminum alloy-resin composite and an aluminum alloy-resin composite obtainable by the same are provided. The preparation method may comprise: S1: anodizing a surface of an aluminum alloy substrate to form an oxide layer on the surface, in which the oxide layer is formed with nanopores;S2: immersing the resulting aluminum alloy substrate in step S1 in an alkaline solution having a pH of about 10 to about 13, to form corrosion pores in an outer surface of the oxide layer, wherein the alkaline solution is an aqueous solution containing at least one selected from a soluble carbonates, a soluble alkali, a soluble phosphate, a soluble sulfate and a soluble borate;S3: injection molding a resin onto the surface of the resulting aluminum alloy substrate in step S2 in a mold to obtain the aluminum alloy-resin composite.
