A PATTERN FORMING METHOD FOR ALUMINUM OR ALUMINUM ALLAY AND AN ALUMINUM OR ALUMINUM ALLAY PRODUCT THEREBY

摘要

This invention is a new method and aluminum or fabricated thereby forming a three-dimensional pattern on the alloy and colorful as for the aluminum or aluminum alloy product, the process of the polished work piece (2) made of aluminum or aluminum alloy (A) and the workpiece (2) to the first anodic oxidation process (B) and, the blood the workpiece (2) to within Yamauchi process of forming a first resist pattern (10) of the alkaline (C) and the workpiece (2) to the primary as an etchant to form a first etching process, referred to as surface 6 ( D), a second resist pattern of alkali to the first peelable acid etched surface (6) (20) during the formation of the (E) and, the work piece (2), the second referred to as the second acid etching solution process of forming the etched surface (8) (F) and the step of removing the second resist pattern 20 by immersing the work piece (2) to the alkali solution (G) and the workpiece (2) to 2 the process of anodization difference (H) and said workpiece (2), the sealing process of the process (I) and, the first resist pattern 10 including the process (J) for the removal of aluminum, characterized in that made or a method of forming a pattern on the aluminum alloy and thereby the production of aluminum or aluminum alloy product is provided.
