方法が行われている。Metals such as iron and aluminum are often subjected to cold plastic working in recent years. In these processes, it is necessary to closely adhere lubricant to the material surface in order to prevent seizure, cracking, etc. during processing. In addition, in order to ensure good adhesion of paint during the painting process, a pretreatment method for a metal surface is generally to form a phosphate chemical film or oxalate chemical film on the metal surface, and then apply a lubricant on top of it. , the method of painting is being done.
しかしながら銅及び銅合金については上記のような処理

A method has been proposed in which a phosphate conversion film is formed thereon, or the surface of the material is roughened by shot blasting, and then the surface is treated with chromic anhydride (Japanese Patent Publication No. 57-37968). However, these methods require long steps, high costs, and use chemicals that cause pollution problems, so improvements are desired.

820f32-eH202 is used.
しかし、銅はイオン化傾向が水素よシ小であるため、上
記反応が起シにくいのである。However, since copper has a smaller ionization tendency than hydrogen, the above reaction is less likely to occur.

ることが判明し念。As a result of the study, active oxygen-releasing oxidizing agents such as persulfuric acid and persulfates (beloxonisulfates), chloric acid and chlorates, perchloric acid and perchlorates, and periodic acid were found. Salts, perboric acid, permanganates, dichromates, hypochlorites, peracetic acid, hydrogen peroxide, and other inorganic and organic peroxides are added to a phosphate chemical treatment solution at a certain concentration or higher. It has been found that it is possible to form a phosphate chemical conversion film on the surface of copper and copper alloys by allowing the presence of copper.
酸化剤の濃度は活性酸素として０．１係（重量割合、対
処理液、以下同じ）以上が好ましい。上限は特に限定さ
れるものではないが、・１度が高すぎる場合は酸化剤の
分解消費率が大になり経済的に不利である。The concentration of the oxidizing agent is preferably 0.1 factor (weight ratio, relative to the processing liquid, the same applies hereinafter) as active oxygen. The upper limit is not particularly limited, but if the temperature is too high, the decomposition and consumption rate of the oxidizing agent will increase, which is economically disadvantageous.
実用上、活性酸素に換算して０．１〜１０％が妥当で、
とくに０．３優〜２チの範囲が好ましい。また酸化剤は
処理に従って消費されるので上記濃度範囲に保つように
項次追加して行く必要がある。Practically speaking, 0.1 to 10% in terms of active oxygen is appropriate.
In particular, a range of 0.3 to 2 is preferable. Further, since the oxidizing agent is consumed as the process progresses, it is necessary to add it periodically to maintain the concentration within the above range.
