Abstract (en)

[origin: US4379723A] A method of removing electrocatalytically active protective coatings from electrodes with metal cores, in which a non-adhesive intermediate layer of a compound of the substrate metal is produced in a position between the protective coating and the substrate structure by means of controlled thermal treatment. By using the method, deactivated protective coatings can be removed in a particularly easy manner from electrodes with valve metal cores.
