An electrode structure containing an insoluble metal electrode which is used as an electrode for the electrolysis of an acidic aqueous solution under a high current density is disclosed. An elastic electroconductive material, containing an expanded metal, having formed thereon a corrosion-resistant electroconductive coating, is disposed between an electroconductive electrode substrate and an electrode having on the surface thereof a coating of an electrode material. They are fixed by a detachable fixing device from the surface of the electrode. The electrode can be exchanged when fixing the electrode structure to the electrolytic cell.

Electrode structure

A method for the electrolytic pin plating of a steel plate using an insoluble anode, said anode being an insoluble electrode comprising a corrosion-resistant metal substrate having provided thereon a coating containing a platinum group metal or an oxide thereof, said anode being enclosed with a diaphragm.

Method for electrolytic tin plating of steel plate

A method for the electrolytic pickling or degreasing of a steel plate in an aqueous solution having an electrode disposed therein, wherein an insoluble electrode or a ferrite electrode is used as the electrode, said insoluble electrode comprising an electrically conductive substrate having provided thereon directly or through an intermediate layer, an electrode coating containing a platinum group metal or an oxide thereof.

Method for the electrolytic pickling or degreasing of steel plate

An electrode protector, which is to be attached to the surface of an insoluble metal electrode for use as the counterpart electrode in a continuous electrolytic treatment of a metal strip or the like and serves to prevent short circuiting, comprising a mesh substrate made of a corrosion-resistant metal, and provided on the surface of the mesh substrate, a corrosion-resistant electrically insulating coating.
