Abstract: Disclosed is a method of treating the surface of an aluminum substrate, including (a) forming a porous oxide film on the surface of the aluminum substrate and (b) applying a corrosion inhibitor on the surface of the aluminum substrate having the oxide film formed thereon. The method of treating the surface of the aluminum substrate enables the formation of the porous oxide film on the surface of the aluminum substrate through surface treatment so that the applied corrosion inhibitor is partially absorbed into the porous oxide film, thus exhibiting superior corrosion resistance and anti-fouling effects of the metal substrate, compared to conventional surface treatment methods involving coating only with a corrosion inhibitor.
