Abstract (en)
[origin: EP0018522A1] 1. A method of maintaining cathodic corrosion protection for metal surface which are in contact with an electrolyte, with external current, using an inert electrode as the external current anode and a potentiostat, characterised in that periodically the protective current is switched off and a measurement is taken of the potential (Eist ) directly between the external current anode which in this phase operates as a reference electrode, and the surface to be protected, and the potential (Eist ) is compared to the protective potential (E soll ) which is set at the potentiostat, and the difference (E ist - E soll ) is used directly as a control value in respect of the protective current.
