An electrode which is suitable for use in devices for protection against corrosion with the applied electric power and the method for protecting an electrically conductive substrate from corrosion

摘要

Methods of preventing corrosion in which current flows between the to-be-protected substrate and a distributed electrode whose electrochemically active surface provided by an element which is composed of a conducive polymer and which is at least 500 microns thick. In one embodiment, the electrode is a flexible strip comprising a highly conductive core, eg. of copper, and a conductive polymer element surroundng the core. In another embodiment, the electrode is a conductive polymer layer which conforms to the surface of the substrate but is separated from it by a layer of insulation.
