本発明は電気メッキ用高耐食性通電ロールに関するもの
である。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a highly corrosion-resistant energizing roll for electroplating.
（従来の技術）

給口５からメッキ液６を供給し、通電ロール２を介して
鋼帯１全陰極とし、電極４を陽画として通電し、鋼帯１
に連続してメッキ全施すことが行なわれている。(Prior art) For example, in continuous electrogalvanizing, etc., as shown in FIG.
As shown in the figure (supplying the plating solution 6 from the supply port 5 at approximately the center of the electrode 4, using the energizing roll 2 as the steel strip 1 as a total cathode, and energizing the electrode 4 as a positive electrode, steel strip 1
Plating is applied continuously to all parts.
かかるメッキに於いては、通電ロール２がメッキ液６に
常時接触しており、このメッキ液は一般に酸性度が高＜
、ｐＨが低く、従って通電ロール２表面が電解腐食し
、肌荒れ金生じ、銅帯１表面に疵全つけ、長期の使用に
耐えない欠点があった。In such plating, the current-carrying roll 2 is constantly in contact with the plating solution 6, and this plating solution generally has a high acidity.
, the pH was low, and therefore the surface of the energizing roll 2 was electrolytically corroded, a rough surface was formed, and the surface of the copper strip 1 was completely scratched, making it unsuitable for long-term use.
このため従来鋼製ロール表面にＮｉ、Ｃｒ等のメッキ処

金メッキが提案され、又特公昭５８−５７５００号公報
では、Ｎｉ −Ｍｏ Ｃｒ系の耐食耐摩耗合金の通電
ロールが開示されているが、まだ十分とは言えない。For this reason, steel rolls whose surfaces have been plated with Ni, Cr, etc. have been conventionally used. For example, JP-A-58-14
No. 1399 proposes a Ni-Cr-Mo-W-based alloy plating, and Japanese Patent Publication No. 58-57500 discloses a Ni-Mo-Cr-based corrosion-resistant and wear-resistant energized roll. I can't say it's enough.
本発明はこのような欠点全有利に解決するためなされた
ものであり、電気腐食、摩耗全防止し、耐久性全向上し
た通電ロール全提供するものである。The present invention has been made to advantageously solve all of these drawbacks, and provides a current-carrying roll that is completely prevented from electrical corrosion and abrasion and has improved durability.
（問題点全解決するための手段）
本発明の特徴とするところは、ロール表面にＴａ８２又

に於ては、第１図に示すごとく例えば金属製（鋼、ステ

覆層７を設けたものである。(Means for Solving All Problems) The present invention is characterized by a highly corrosion-resistant current-carrying roll for electroplating, characterized in that a coating layer of Ta82 or TiC is provided on the roll surface. That is, in the present invention, as shown in FIG. 1, a coating layer 7 of TaB2 or TiC is provided on the surface of a roll 20 made of, for example, metal (steel, stainless steel, etc.).
ＴａＢ２． ＴｉＣは耐食性、耐硬性に優れ、かつ導電
性も十分確保でき、通電ロールとして優れた性状全付与
することができる。TaB2. TiC has excellent corrosion resistance and hardness resistance, and can also ensure sufficient electrical conductivity, and can provide excellent properties as a current-carrying roll.
被覆方法としてはプラズマ溶射が用いられるが他に蒸着
、箔に加工し、直接貼る方法もあり、被覆量としては０
．１１以上あれば良い。このような金属は直接鋼等の表
面に付着しにくいので、例えばＴａ等を下地に被覆する
ことが好ましい。Plasma spraying is used as a coating method, but there are also methods such as vapor deposition, processing into foil, and directly pasting.The coating amount is 0.
．． It is good if it is 11 or more. Since such metals are difficult to adhere directly to the surface of steel or the like, it is preferable to coat the base with, for example, Ta or the like.
金属ロール２に被覆したＴａＢ２． ＴｉＣの溶射層の
気孔が多発した場合は、例えばフェノール樹脂やフッ素
樹脂等により埋める方法、又は金属Ｔａ全アンダーコー
トとして被覆することで、ロール母材の耐食性全改良す
る。TaB2 coated on metal roll 2. If a large number of pores occur in the TiC sprayed layer, the corrosion resistance of the roll base material can be completely improved by filling them with, for example, phenol resin or fluororesin, or by coating the pores with a metallic Ta undercoat.
