Embodiment 1
[0031] Select the aluminum alloy material and punch it into an aluminum alloy sheet through a punching machine; the aluminum alloy sheet is stretched and formed into a cooker structure through a prepared drawing die, and then the rough edges are trimmed and cleaned with vegetable oil to form an aluminum alloy cooker blank.
[0032] The stretched cookware blank is placed in the shot blasting equipment, and the cookware blank is shot blasted through stainless steel shots with a particle size of 0.1 to 0.8mm; the cookware blank is shot blasted to form a surface with a certain roughness; thus It imitates the micron-scale structure of the surface of the lotus leaf. In addition, the cookware blank has the effect of cold hardening after shot blasting, which can strengthen the cookware blank.
[0033] Put the shot blasted cookware blank into the concentrated sulfuric acid electrolyte for anodic oxidation. The cookware blank is used as the anode, and the aluminum plate is used as the ca...
