Description
【考案の詳細な説明】 本考案は電気メツキ用電極支持部材に関する。[Detailed explanation of the idea] The present invention relates to an electrode support member for electroplating.
一般に、連続電気メツキライン、特に、水平型ラインに
おける電極支持部材は、メッキ液中で電極をその上に静

いう機能を有している。In general, an electrode support member in a continuous electroplating line, particularly in a horizontal line, has the function of holding the electrode stationary thereon in the plating solution and supplying current to the electrode through it.
従って、このような電極支持部材に要求される特性とし
ては、（１）メッキ液に対する耐食性があること、（２
）メッキ液中で正極の電位を与えても溶解しないこと、
（３）通電性の良好なこと等があげられる。Therefore, the characteristics required of such an electrode support member are (1) corrosion resistance against plating solution;
) It does not dissolve even if a positive electrode potential is applied in the plating solution;
(3) Good conductivity, etc.
しかしながら、従来において電気メツキ用電極支持部材
の被覆材としてＰｂやＴｉ等の金属が使用されていたが
、Ｐｂを電極支持部材の被覆材として使用した場合には
、メッキ液中で正極の電位を与えるとｐｂが徐々に溶解
しこのメッキ液から得られるメッキ皮膜は外観、耐食性
、化成処理性等の性態が低下するようになり、また、Ｔ

と電極支持部材の部分で電極に接していないＴｉ表面が
不働態化し通電する電気量が増減することによって電位
が変動した時に不働態化皮膜が破壊されてスパークが発
生するという不都合が生じる。However, in the past, metals such as Pb and Ti have been used as coating materials for electrode support members for electroplating, but when Pb is used as a coating material for electrode support members, the potential of the positive electrode is reduced in the plating solution. When given, PB gradually dissolves, and the properties of the plating film obtained from this plating solution, such as appearance, corrosion resistance, and chemical conversion treatment properties, deteriorate.
When Ti is used as a covering material for an electrode support member, the above three properties are almost satisfied, but there is a problem due to the characteristics of Ti, that is, when a positive electrode potential is applied, the electrode and electrode support member The Ti surface that is not in contact with the electrode becomes passivated at the part, and the amount of electricity supplied increases or decreases, causing the inconvenience that when the potential fluctuates, the passivation film is destroyed and sparks are generated.
そして、このスパークによって局所的に孔食を生じ電極
支持部材の補修回数が増大するという問題がある。This spark causes local pitting corrosion, which increases the number of times the electrode support member must be repaired.
本考案は上記した従来の電極支持部材の問題点に鑑み、
メッキ液に対する耐食性があり、メッキ液中で正極の電
位を与えても溶解しないで通電性が良好で、かつ、耐ア

のである。The present invention has been developed in view of the problems of the conventional electrode support members mentioned above.
An object of the present invention is to provide an electrode support member for electroplating that has corrosion resistance against a plating solution, does not dissolve even when a positive electrode potential is applied in the plating solution, has good conductivity, and has arc resistance.
