金属箔製造用電着ドラム材または金属箔製造用電着ドラムの検査方法

Japanese Patent JP7269472

B2

To provide a method of inspecting an electrodeposition drum material for producing metal foil or an electrodeposition drum for producing metal foil, capable of nondestructively performing quality inspection of the whole of an electrodeposition drum material for producing metal foil or an electrodeposition drum for producing metal foil.SOLUTION: The method of inspecting an electrodeposition drum material for producing metal foil or an electrodeposition drum for producing metal foil according to the present invention, comprises a first process of causing a pair of conducting electrode probes to contact the surface of an electrodeposition material made from industrial pure titanium or a titanium alloy for producing metal foil or of an electrodeposition drum for producing metal foil comprising the electrodeposition material for producing metal foil, to supply the surface with a constant electric current, and causing pairs of potential detection probes to contact the surface supplied with the constant electric current at a plurality of positions thereof at a specified probe interval apart to detect a plurality of voltages at the plurality of positions on the surface, and a second process of comparing two or more of voltages selected from the plurality of voltages.SELECTED DRAWING: Figure 1
