ABSTRACT:
A long-term electrode for electrolytic processes comprises a skeleton of a metal passive under the conditions of the electrolytic process and an electrically conductive first coating which is bound to the metal skeleton in a tightly adhesive manner covering at least part of the metal surface and to which is applied electrochemically active substances selected from the group of platinum metals and platinum metal compounds.
The first coating is produced on the metal surface by flame or plasma spraying. Subsequently at least one electrochemically active substance containing a platinum metal or oxide thereof is formed by a thermal degradation process and anchored to the pores of the first coating.
