Document Type and Number:
WIPO Patent Application WO/2015/093159
Kind Code:
A1
Abstract:
Provided is a method for performing an electropolishing treatment on an aluminum material, the method making it possible to readily produce aluminum materials having uniform luster and exceptional appearance on an industrial scale. The method for performing an electropolishing treatment on an aluminum material involves performing an electropolishing treatment on the surfaces of an aluminum material by immersing the aluminum material in an electrolytic treatment solution within an electrolytic treatment tank, and, using the aluminum material as an anode, applying an electrolysis voltage, wherein the method comprises a method in which an anodization treatment is carried out as a pretreatment for the electropolishing treatment, a method in which a bubble-diffusion-preventing treatment is carried out during the electropolishing treatment, and a method in which an electropolishing-film-peeling process is carried out as a post-treatment for the electropolishing treatment.
