５頁参照）。Conventional technology and its problems The coloring method of anodizing an aluminum alloy material and dyeing the anodic oxide film formed on the surface with a dye is known from the past (published by Uchida Rokakuga Co., Ltd., “Surface Treatment of Aluminum” by Sadatsugu Kokubo, 158-16

問題があった。However, the coloring method described above has a problem in that the 1D color is too bright and it is not possible to obtain an opaque colored product.
この発明の目的は、用途に応じて不透明な着色を施しう

のである。Means and Effect for Solving the Problems In order to achieve the above object, the method for opaquely coloring an aluminum alloy material according to the present invention is to apply an oxalic acid to an aluminum alloy material made of an aluminum base alloy containing 0.5 to 4.0% of CuO. °1
The process of anodizing by bath dissolution to form an anodized film on the surface, and the subsequent step of increasing the voltage by 5% from the previous voltage value in the same electrolytic bath.
The step of making the anodic oxide film opaque by applying constant voltage electrolytic treatment at a sudden drop of ~35V, and finally the opaque layer formed on the surface! This process consists of a step of dyeing a polarized film.
なお、％は重量基準とする。Note that % is based on weight.
上記において、銅の含有辺を０．０５〜４゜０％に限定
したのは、０．０５％未満では所期する色が得られず、
また４％を超えると、形成せられた陽極酸化皮膜が軟質
となり、耐食性が乏しいことによる。しゅう酸電解浴に
よる￥Ｑ橘酸酸化処理条件、常法どおりである。In the above, the reason why the copper content was limited to 0.05 to 4°0% is because if it is less than 0.05%, the desired color cannot be obtained.
Moreover, if it exceeds 4%, the formed anodic oxide film becomes soft and has poor corrosion resistance. The conditions for the oxidation treatment using oxalic acid electrolytic bath were as usual.
電圧を急激に降下させた後定電圧電解を行なった場合、
電流はすぐに流れず、数秒〜数分経過後徐々に流れ始め
、しばらくして定常状態に達する。この現象は回復現象
と呼ばれている。If constant voltage electrolysis is performed after the voltage has suddenly dropped,
The current does not flow immediately; it begins to flow gradually after several seconds to several minutes, and reaches a steady state after a while. This phenomenon is called a recovery phenomenon.
この回復現象によって、陽極酸化皮膜が形成されるとと

ましい電圧は２０〜２５ｖである。電解処理時間が５分
未満では下地アルミニウム合金の粗面化が進まず、また
２５分を超えると、粗面がなくなる傾向にあるので、処
理時間は５〜２５分、特に１０〜２０分が好ましい。Due to this recovery phenomenon, an anodic oxide film is formed and the aluminum alloy surface underlying the anodic oxide film is uniformly roughened. This diffused reflection on the rough surface makes the anodic oxide film appear opaque. In the above, the voltage was limited to 5 to 35 ■.If it is less than 5V, the current recovery is small and the surface roughening of the underlying surface does not proceed.If it exceeds 35V, an oxide film is rapidly formed and the underlying surface becomes rough. This is because there will be no surface left. A particularly preferred voltage within this voltage range is 20 to 25V. If the electrolytic treatment time is less than 5 minutes, the surface roughening of the base aluminum alloy will not proceed, and if it exceeds 25 minutes, the rough surface will tend to disappear, so the treatment time is preferably 5 to 25 minutes, particularly 10 to 20 minutes. .
