M361504 IV. Designated representative map: (1) The representative representative of the case is: (4). (2) Brief description of the symbol of the representative figure: (1) Ming substrate (11) First oxide layer (12) Protective layer (13) Exposed portion (14) Second oxide layer V. New description: TECHNICAL FIELD [0001] The present invention relates to a multi-color structure of an is alloy surface 5, in particular, a protective layer such that the second oxide layer is not formed on the outer surface of the first oxide layer to avoid overlapping Multi-color structure of the surface of the alloy [previous technique #f] [0002] According to the general aluminum alloy, it is easy to oxidize, although the oxide layer has a certain

Passivation, but as a result of long-term exposure, the oxide layer will still peel off and lose its protective effect. Therefore, it is usually anodized on the surface of the aluminum alloy. The purpose is to control the formation of the emulsion layer by using the characteristics of easy oxidation. In order to prevent further oxidation of the name material and increase the mechanical properties of the surface, the above-mentioned anode treatment is an electrolysis process, the metal sheet providing the plated metal acts as the anode, the object to be plated acts as the cathode, and the electrolyte is usually the plating layer. The metal ion solution is connected to the input voltage between the anode and the cathode, and then the metal ions in the electrolyte are attracted to the cathode. After the metal ions are reduced, the metal ions are plated thereon, and the metal piece of the anode is redissolved to provide an electrolyte. A large amount of metal ions, and in some cases an insoluble anode will be used, so that an electrolyte must be added during plating to fill the form number A0101 page 2 / total 10 pages M361504 charge metal ions. [0003] When the above-mentioned aluminum alloy is subjected to anodizing treatment (generally referred to as decorative anodizing treatment), a bright and corrosion-resistant film is formed on the surface of the aluminum alloy, and the film thickness of the film is about 6 β to 15// or so, it can protect both the base material and the beautification function. At the same time, it can also provide the surface properties that the raw materials cannot provide by changing its physical properties or chemical properties, and the film system can choose the glossy surface treatment according to the customer's preference. Or matte treatment (pear surface treatment), because the formed film is porous and has excellent permeability, the film can be immersed in an organic or inorganic dye to penetrate into the pores of the film to form various colors and patterns. Finished products, with a variety of colors, are the characteristics of general anodizing, and the products used for aluminum materials are the best appearance protection method. [0004] However, the above-mentioned anode treatment method has the following defects in actual use: [0005] 1. The above-mentioned anode treatment method requires a plurality of anode treatments.

In order to form a plurality of colors, it is necessary to perform surface treatment such as cutting, polishing or laser engraving on the aluminum alloy between the respective anode treatments to remove the film produced by the previous anodizing treatment, so as to form another color at the surface treatment. The film, but the surface treatment often requires the use of cutting fluid or coolant, so that the surface treated aluminum alloy will residual oil collapse, resulting in the next anode treatment, the other film produced on the oil collapse will easily fall off, resulting in anode The increase in the rate of treatment failure. [0006] 2. The above-mentioned anodizing treatment method has a defect that it is easy to fall off due to the newly produced film, and not only affects the overall color development effect, but also forms No. 1010101 Page 3/10 pages M361504 In this case, even the overall strength is reduced.
