いる。DETAILED DESCRIPTION OF THE INVENTION In the present invention, electrodes, copper electrodes, etc. used in electroplating such as zinc plating, tin plating, nickel plating, and copper plating have been widely used. However, these electrodes dissolve due to electrolytic dissolution and chemical dissolution during plating. Therefore, the electrode wears out as it is plated, so if the distance between the plating material and the electrode (distance between the electrodes) is not kept constant during plating, the quality of the plated product will vary, so the distance between the electrodes must be kept constant. This creates a complicated process in which the electrodes must be adjusted or replaced frequently depending on the degree of wear.

オンを除去しなければならない等の欠点も生じる。Furthermore, while the dissolution of these electrodes has the advantage of replenishing metal ions into the plating bath, depending on the plating speed, the metal ions in the plating bath may increase too much, which may have a negative effect on the quality of the plated material. There are also drawbacks such as the need to remove these dissolved metal ions.

ものが少なく種々の欠点を生じている。In order to solve these drawbacks, a conventional method has been used for electroplating using an anode material that is very unlikely to be dissolved by electrolytic dissolution or chemical dissolution, that is, an insoluble anode. However, there are currently few insoluble anode materials in such plating methods that are completely satisfactory, resulting in various drawbacks.

陽椿である。In addition, electrodes made by plating titanium with platinum (thickness 3 to 5 μm) are used for tin plating or zinc plating, but even with this platinum plating, the cost of platinum plating is quite high, and Because platinum is soft, the platinum plating layer is not only dissolved by electrolysis but also peeled off by polishing etc. due to the solid floating matter (sludge) generated in the plating bath, and its lifespan is not very long, making it difficult to improve economic efficiency and There is a problem in terms of the complexity of replacing electrodes.1゜The present invention solves the problem of electrolysis of zinc anodes, copper anodes, nickel anodes, and copper anodes (due to the drawbacks caused by the electrolysis of zinc anodes, copper anodes, nickel anodes, and copper anodes) and the insoluble anodes currently used in some cases. The purpose is to provide a positive material that solves the drawbacks, and its gist is that it contains 51 or more iron (by weight), 1096 or more nickel, and the total amount of iron and nickel is 20 ~40%, with the remainder consisting of titanium and non-sewable impurities.

Forms a passive film on the surface to reduce electrical conductivity. In order to prevent this deterioration, iron and nickel are mixed. Iron is a cheap and effective component that makes titanium □ conductive, with a 5%
If the content is less than that, the effect cannot be obtained. In addition, nickel prevents cracks that occur during the cooling process of molten titanium and iron after casting, and because it has a higher natural potential than iron, it significantly improves electrical conductivity and significantly reduces the amount of waste when energized. It has a suppressive effect.

The amount was limited to 20 to 40% to provide the necessary electrical conductivity and the effect of suppressing electrical consumption as an electrode material.
