Abstract
A metal-and-resin composite includes an aluminum or aluminum alloy substrate, an aluminum oxide film on the aluminum or aluminum alloy substrate, and at least one resin article coupled to the aluminum oxide film. The aluminum or aluminum alloy substrate defines a plurality of corrosion pores, and the aluminum oxide film defines a plurality of nano-pores. Some of the nano-pores extend through the aluminum oxide film and couple to the corrosion pores. Some parts of the resin article fill in the nano-pores and the corrosion pores, thus greatly improving bond between the resin article and the aluminum or aluminum alloy substrate.
