Abstract
A method of preparing an aluminum alloy resin composite comprises: providing an aluminum alloy substrate having an oxide layer on a surface thereof, wherein the oxide layer has one or more nanopores; forming one or more corrosion pores on an outer surface of the oxide layer by using a corrosion agent, wherein the corrosion agent is at least one selected from a group of ammonia, ammonium salt, hydrazine, hydrazine derivative, and water-soluble amine compound; and injection molding a resin composition to the surface of the aluminum alloy substrate.
Claims18
A method of preparing an aluminum alloy resin composite, comprising:
- providing an aluminum alloy substrate having an oxide layer formed by anodic oxidation on a surface thereof, wherein the oxide layer has nanopores;
- forming corrosion pores on an outer surface of the oxide layer by using a corrosion agent, wherein the corrosion agent is at least one selected from a group of ammonia, ammonium salt, hydrazine, hydrazine derivative, and water-soluble amine compound, wherein the corrosion pores have a larger diameter than the nanopores, the corrosion pores and the nanopores form a double-layer pore structure, and the corrosion pores are in communication with the nanopores;
- and
- injection molding a resin composition to the surface of the aluminum alloy substrate through the nanopores and the corrosion pores, wherein the resin composition is fixedly attached to the aluminum alloy substrate.
