PATTERN FORMATION OF THE ALUMINUM OXIDE FILM DEVICES

摘要

The present invention relates to a device to form an oxide film pattern of aluminum and, more specifically, to a device to form an oxide film pattern of aluminum capable of easily forming a matt specific pattern on the surface of an aluminum material (20) and anodizing only the part to be printed. According to the present invention, the device to form the oxide film pattern of the aluminum includes: an electrolyzer (10) whereby an electrolyte (5) is accommodated; a working electrode (30); and a counter electrode (40) to anodize the surface of the aluminum material (20).
