Description of the Invention: [Technical Field] The present invention relates to a metal surface anode treatment method, and more particularly to a multi-color anode treatment method that can be used for a curved surface. [Prior Art] Ming, Qin and its alloy materials are widely used in aviation, electronics, communications and other fields due to their high strength and light weight. In order to further improve the surface quality and visual effect, the industry usually uses anodizing process or painting method to achieve. A method for decorating a titanium-based article is disclosed, for example, in U.S. Patent No. 5,215, the disclosure of which is incorporated herein by reference. The voltage controls the color of the surface oxide layer, and the thickness of the emulsion film obtained by the method is “--the lack of a three-dimensional feeling of concave. The conventional anodizing process also has a method of obtaining an oxide film of different colors by using multiple anode treatments and multiple coloring, but this method can obtain a multi-color oxide film on a metal surface, but each treatment can only be the same - Performed on a plane, no ^ person) Born on the surface to obtain a continuous three-dimensional color pattern. The paint pattern is simple, the outline is blurred and the adhesion of the paint film is weak. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a metal surface anodizing method capable of obtaining a continuous three-dimensional color pattern on a curved surface. A metal surface anodizing method for treating a surface of a titanium alloy substrate, comprising the steps of: (1) anodizing the substrate to form a gas on the surface of the substrate: 200928005 < ruthenium film; (2) The oxide film is subjected to a coloring treatment; the ink is sprayed on the substrate to completely shield the oxide film on the surface thereof; (4) the non-forest film having the desired pattern of Xingzhuang and _荼 is attached to the sprayed ink 1 body U-light treatment 'curing is not partially obscured by the pattern on the film film ❹ (6) removing the uncured ink; (7) removing the oxide film not covered by the ink; (8) performing the second anodizing on the substrate The oxidation film obtained after the first anodic treatment is subjected to coloring (10) to remove the remaining masking ink; (11) Steps (3) to (10) are repeated. The technique of the gossip is carried out by vacuum-bonding the non-forest film which has the required pattern to the photocuring section VIII, and Zhanli (on the emulsified film ink) by first exposure to oxo oxime Eight knives,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, On the curved surface, so that it can be - timed, "the entire surface obtains a continuous and three-dimensional pattern. The same as the ancient low ^ change the conditions of each anodic anode treatment to make the metal surface obtain a texture pattern with low fluctuations [Technical Embodiment] A metal surface anode treatment method according to a preferred embodiment of the present invention is described by taking an anode surface treatment of a metal substrate as an example, and includes the following steps: (1) cleaning a metal substrate with a solution containing a corresponding metal degreaser, Then, the metal substrate is placed in a solution containing phosphoric acid and sulfuric acid for chemical polishing treatment, and then the chemically polished metal substrate is stripped with a solution containing nitric acid. The black film is used to remove a black film formed on the surface of the workpiece by the above chemical polishing treatment. (2) The metal substrate is anodized to form an oxide film on the surface of the metal substrate. In this step, the anode treatment solution contains 18 Å. ~2〇〇g/L of sulfuric acid and less than 20g/L of aluminum ion, the treatment voltage is u~13v, and it is treated at room temperature for 30~50 minutes. (3) Adsorption or coloring of the above-mentioned anodized metal substrate or Chemical coloring treatment (4) The above-mentioned colored metal substrate is subjected to a sealing treatment to improve the anti-pollution and anti-corrosion properties of the surface oxide film. (5) Spraying the ink on the metal substrate and completely shielding the surface oxide film The ink is a photosensitive ink, and the thickness of the ink is 1 〇 5 5 μm. ' (6) A film film having a desired pattern is vacuum-applied to the metal substrate coated with the ink. a vacuum generator forms a vacuum between the film film and the metal substrate, and the film is attached to the surface of the metal substrate under the vacuum adsorption. The patterned portion of the film has been The light is black, and the non-patterned part is transparent. 200928005 (7) Exposure treatment to cure the oil that is not partially covered by the pattern on the film. The exposure process uses an astigmatism exposure machine with an exposure energy of 1〇0. ~15〇mj/cm2, the exposure intensity is 5~25. After the treatment in this step, the ink on the base of the two genus that is not blocked by the film on the film is solidified, and the ink blocked by the pattern on the film is not cured. (4) Dissolution The vacuum state causes the film to be detached from the metal substrate to dissolve the uncured ink in a developing solution. (9) Laser engraving or chemical etching removes oxygen not covered by the ink (4) 1 (4) The chemical (4) liquid is 峨, 4Qg/L of sodium hydroxide Loose solution, the cooking time is 1 〇 ~ 6 〇 seconds. (10) The chemical polishing and the metal substrate after the black film is subjected to the first anodic treatment. The chemical polishing and blackening method and the method are the same. The oxidation treatment obtained after the extreme treatment is treated. (12) Sealing the oxide film obtained after the first under-anodic treatment H removes the remaining masking ink by the ink-specific separating agent, that is, β ' ^ , and obtains a pattern with a clear outline and a strong stereoscopic effect on the substrate. It can be understood that the above steps (5) are repeated until (the metal substrate obtains a pattern of more colors. The treatment = every owable =: the condition of each anode treatment such as the oxidation of the anode to the mother-man depolarization treatment) The thickness of the film does not allow the entire metal surface to obtain a high-low relief perspective view 200928005. The method of the present invention is applicable to the surface treatment of metal substrates such as ingots, gold, and titanium alloys. The method of the present invention is made by having the desired pattern The Lin film is vacuum-applied to the masking oxide film ink, and the method of pre-expanding a part of the ink to re-develop a part of the uncured ink to accurately distinguish the area to be anodized again, so that the pattern is finer and clearer. The film can not only be pressed against a certain plane of the metal substrate, but also can be deformed, so that it can also be pressed on the curved surface of the gold matrix, so that it can be applied to the entire surface of the metal substrate at one time. Obtain a continuous and three-dimensional pattern. At the same time, the metal surface is obtained by changing the conditions of each anode treatment. There are many texture patterns with high and low undulations. [Simple description of the diagram] None [Key component symbol description] 〇 No 11
