Summary:The invention discloses a processing method for a cast aluminum alloy workpiece, and a cooker thereof, the cast aluminum alloy workpiece contains silicon. The processing method comprises the steps of dealloying treatment and hard anodic oxidation treatment. The dealloying treatment comprises the steps that the cast aluminum alloy workpiece interacts with an oxidizing acid solution, and the oxidizing acid solution generates a complex reaction on aluminum in the cast aluminum alloy workpiece for protection; silicon in the cast aluminum alloy workpiece is corroded and stripped, and therefore an aluminum element enriched surface is formed; and the hard anodic oxidation treatment comprises the step of carrying out hard anodic oxidation on the cast aluminum alloy workpiece subjected to dealloying treatment, so that a hard anodic oxidation film is formed on the surface of the cast aluminum alloy workpiece. According to the processing method, the hard anodic oxidation treatment quality of the cast aluminum alloy work
