Abstract
Official abstract text for this publication.
A titanium foil or a titanium sheet is produced by electrodeposition from molten salt using constant current pulse, the method comprising: forming an electrodeposited titanium film on a surface of a cathode electrode made of glassy carbon, graphite, Mo, and Ni, and separating thereafter the electrodeposited titanium film from the cathode electrode by performing one or both of applying an external force to the electrodeposited titanium film and removing the cathode electrode. This enables the electrodeposited titanium film electrodeposited on the cathode electrode to be peeled from the cathode electrode simply and at low cost.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a titanium foil or a titanium sheet by electrodeposition from molten salt using constant current pulse, the method comprising: forming an electrodeposited titanium film on a surface of a cathode electrode made of one or more kinds selected from glassy carbon, graphite, Mo, and Ni, and thereafter separating the electrodeposited titanium film from the cathode electrode, wherein the separating process comprises steps of: on an interface between the electrodeposited titanium film and the cathode electrode, forming a grasping portion in the electrodeposited titanium film by removing a portion of the cathode electrode, and thereafter, a) peeling the electrodeposited titanium film from the cathode electrode with the grasping portion as a starting point, or b) bonding a separation member to the grasping portion and then peeling the electrodeposited titanium film from the cathode electrode with the separation member as the starting point. 2. The method for producing a titanium foil or a titanium sheet according to claim 1 , wherein the process of removing comprises a step of: removing by physical means or chemical means.
