ニッケル皮膜は耐蝕性が特に優れ、硬度が高く、耐摩耗

ホールがなく、所望の厚みを有するニッケル皮膜が浸漬
時間に対応して得られる特長を有している。Recently, nickel-plated and blackened products have been widely used for solar heat absorbing plates, optical equipment, ornaments, etc. There are two methods to obtain a nickel film: electroplating and electroless plating. In the electroless plating method, the body to be plated is immersed in an electroless plating bath after pretreatment such as cleaning and activation. It has the advantage that a nickel film having a desired thickness without pinholes can be obtained uniformly over the entire surface in a very short time by just dipping in a short period of time.

に要望される点が多かつた。However, in the latter method, much of the plating coating and substrate are damaged by nitric acid. The former method, which involves painting and chemical conversion treatment, produces a nearly uniform black nickel film, but has drawbacks in light absorption properties, corrosion resistance, and abrasion resistance. Since galvanizing or black galvanizing is performed, the resulting black film is not uniform, and there are many requirements for light absorption, abrasion resistance, and corrosion resistance.

。The present inventors conducted research to eliminate the above-mentioned drawbacks, and to provide a method for forming a black nickel film on the surface almost uniformly with excellent light absorption, abrasion resistance, and corrosion resistance.
When performing electroless nickel plating, a phosphoric acid-based compound is used as a reducing agent to form a film containing phosphorus in the nickel plating layer on the surface of the workpiece, and then the plated product is coated with acidic permanganate. The present invention was completed based on the knowledge that the nickel plating layer becomes extremely black if the two are immersed in a solution to react. The gist of the present invention is that electroless nickel plating is applied to the surface of the object to be treated using a phosphorus compound as a reducing agent, and then the electroless nickel plating film is immersed in a permanganese acetic acid bath. .

〜１５重量％であることが好ましい。The object to be treated is not limited to any material as long as it can be subjected to electroless nickel plating, such as metal, porcelain products, and plastic products. The phosphorus compound 5 to which electroless nickel plating is applied is a compound that exhibits reducing properties, such as hypophosphite, and phosphorus is present in the plating coating layer obtained by electroless nickel plating.
Preferably it is 15% by weight.

などの酸溶液に溶解したものが用いられる。過マンガン
酸イオン濃度は特に限定されないが１．０〜２０ｔ／１
１硫酸濃度は５〜１００ｒ／１であることが好ましい。If the phosphorus content is 15% by weight or more or 1% or less, the reaction with the treatment liquid becomes slow, which is not preferable. The manganic acid acid bath is prepared by dissolving sodium permanganate or potassium permanganate in an acid solution such as sulfuric acid. The permanganate ion concentration is not particularly limited, but is 1.0 to 20t/1.
The sulfuric acid concentration is preferably 5 to 100 r/1.
処理温度は処理する時間、処理液の組成によつて対応さ
れるが、１０〜５０℃が目安となる。The treatment temperature depends on the treatment time and the composition of the treatment liquid, but a rough guideline is 10 to 50°C.
時間は５秒〜５分が目安となる。本発明はまた前述した
方法で得た無電解ニツケルめつき体を陽極にして電解酸
化することによつても、黒色めつき体が得られる。The approximate time is 5 seconds to 5 minutes. In the present invention, a black plated body can also be obtained by electrolytically oxidizing the electroless nickel plated body obtained by the above-described method as an anode.
これによつて金属表面にさらに一層均一に黒色ニツケル
皮膜を形成することができる。本発明の方法によれば、
黒色ニツケル皮膜はなんら損傷せずに、密着性がすぐれ
、かつ均一に耐蝕性及び耐摩耗性にすぐれた超黒色化し

できる。This makes it possible to form a black nickel film even more uniformly on the metal surface. According to the method of the invention,
A super black electroless nickel plating film with excellent adhesion, excellent corrosion resistance and abrasion resistance can be uniformly formed on the surface of the black nickel film without any damage.
