[0002] Alloy surface treatment is a treatment method that performs a series of processing on the surface structure of the alloy to make the processed product have functions such as anti-corrosion and anti-rust. It only includes processes such as pickling and passivation, and lacks relevant requirements for the steps of alloy pretreatment and drying treatment, which may lead to water stains on the surface of the alloy cost or imperfect processing products, etc., which need to be improved

[0003] Chinese Patent No. CN110359047A discloses a surface treatment method for an aluminum alloy, which includes the following steps: performing alkali etching on an aluminum alloy to form a first structure on the surface of the aluminum alloy, the first structure comprising a plurality of evenly distributed the first groove; washing the aluminum alloy with water; acid etching the aluminum alloy to form a second structure part, the second structure part comprising a plurality of second grooves uniformly distributed on the first structure part, The surface of the aluminum alloy treated by the invention has a uniform and delicate white atomized appearance. The concentration of chemical reagents used in the aluminum alloy surface treatment method of the invention is low, and the corrosion amount to the aluminum alloy is less than 5%, which avoids damage to the size of the aluminum alloy. The aluminum alloy surface treatment method of the invention avoids the use of fluorine-containing ion reagents, which is safer during processing and production. In this method, the invention only has the function of pickling protection for the alloy, and lacks a perfect pretreatment process for the alloy, and furthermore The effect of the treatment of the alloy has caused an impact and needs to be improved

[0004] Chinese Patent No. CN113604805A discloses a method for surface treatment of an alloy, comprising the following steps: the alloy undergoes pickling treatment, cleaning treatment and passivation treatment respectively; Treatment in the pool and passivation pool, the pickling pool, cleaning pool and passivation pool are separated from each other by a rolling door, pickling solution is placed in the pickling pool, distilled water is placed in the cleaning pool, and passivation solution is placed in the passivation pool; The car is placed in the operation room, and a pair of slide rails are set on the bottom surface of the operation room. The rollers on the transfer car are placed on the slide rails, and the transfer car moves on the slide rails; the transfer car passes the alloy to be treated through the pickling pool in turn, The cleaning tank and the passivation tank are processed, and when passing through the pickling tank, the cleaning tank and the passivation tank, the separation and sealing between the various processes are realized by opening and closing the shutter door. The inventive device has high processing efficiency and is safer In this method, the main treatment methods in this invention are pickling and passivation, but there is no drying treatment process for the alloy surface, and the records of the execution methods of each step are not detailed enough, and there is no corresponding data support for the finished product effect of the alloy. make improvements
