クロメート皮膜を有するめつ外装品およびその製造法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an eyewear exterior product having a golden chromate film formed on a nickel plating film, and a method for manufacturing the same.

により金属製品の耐食性を向上させるために行われる。As is well known, electrolytic chromate treatment is performed to coat the surface of a metal product with xcr20.・yCrO3・zH
This process is carried out to improve the corrosion resistance of metal products by forming a so-called chromate film consisting of 20% chromate.

ロメート皮膜を形成させるのが普通であった。Typical metal products subjected to electrolytic chromate treatment include chrome chromate steel plates (Tin Free 5teel) and steel plates to be painted (this treatment is performed to improve the adhesion of the paint). The chromate film formed by these electrolytic chromate treatments can be either uncolored or colored, depending on the treatment conditions and the type of metal to be treated, and there are various colored tones. When electrolytic chromate treatment is applied to nickel plating film]2, the resulting chromate film is colorless and transparent on the outside when it is very thin, but as the film becomes thicker, it develops uneven striped interference colors like a rainbow. This results in an undesirable appearance. It has conventionally been considered extremely difficult to form a uniformly colored chromate film on a nickel eyelash outer film, regardless of the color tone. Therefore, nickel-plated articles are not often subjected to further electrolytic chromate treatment, and when they are, it is common to form a very thin chromate film that does not cause coloration.

は、電解クロメート処理あるいは多重メッキ処理の常識
に反して、電解クロメート処理によりぎわめて均一で、
しかも美麗な金色のクロメート皮膜が形成されることを
見いだしたのである。However, in the course of research on post-treatment of nickel plating, the present inventors found that if the surface outside the nickel plating was not a fresh active surface and an oxide film had been formed there, electrolytic chromate treatment or multiple plating could be applied. Contrary to common knowledge about processing, electrolytic chromate treatment is extremely uniform,
Moreover, they discovered that a beautiful golden chromate film was formed.

・ンケルめつ外皮膜上に均一な金色のクロメート皮膜を

製造する方法の発明である。The present invention has been completed based on the above findings, and is produced by placing an oxidation step between the metal treatment step and the metal treatment step, which has a uniform golden chromate film on the outer skin of the eyelid. It is an invention of a method.
以下、本発明の製造法を工程順に説明する。Hereinafter, the manufacturing method of the present invention will be explained in order of steps.

ケルめっきを包含するものである。The first nickel plating can be done using any method, and there are no restrictions on the type of plating solution, the thickness of the plating, etc. Further, in the present invention, nickel plating includes not only simple nickel plating but also the following special nickel plating.
（イ）鉄、コバルト、亜鉛、スズ等の金属とニッケルと

うこともで外る。適当な電解条件は、温度が常温〜８０
°Ｃ１電流密度が０．１〜５０Ａ／ｄｍ２である。Since the surface of nickel immediately after plating is in an extremely highly active state, it is possible to form an oxide film to the extent necessary to form a golden chromate film even by leaving it in water containing dissolved oxygen for one hour. If placed in air, oxidation will proceed more rapidly, and a sufficient oxide film will be formed in about 15 minutes, preferably about 30 minutes. The oxidation treatment can also be carried out by electrolyzing the nickel-plated article in a neutral or alkaline electrolyte solution using the article as an anode. Appropriate electrolytic conditions include temperatures ranging from room temperature to 80°C.
°C1 current density is 0.1-50 A/dm2.

ある。These methods are particularly preferred oxidation methods because they do not cause the risk of undesirably excessive oxidation of the nickel film surface and therefore provide sufficient treatment to ensure the effectiveness of the subsequent electrolytic chromate treatment. However, it goes without saying that other oxidation methods may be used as long as they are uniform and can serve as a pretreatment for forming a romate film.

る。The plated products of the present invention obtained by the method described above are of a beautiful golden color.When the present invention is applied to ornaments, various machines, appliances, miscellaneous goods, and their parts for which appearance is important, Hiiragi This results in a marked improvement in decorativeness. Moreover, since the plated products of the present invention both have a nickel plating film and a chromate film that have excellent corrosion resistance, they inherently exhibit a high degree of corrosion resistance, and the color tone also changes at room temperature to about 200°C. It has the feature of being stable for a long period of time. Conventionally, there was a method to obtain a gold-colored plating film without using expensive gold plating, but the drawback of silver plating was that it was easily discolored, and a coating had to be applied to prevent discoloration. The above features of the product of the present invention are extremely significant.
