Abstract (en)
[origin: WO2006053877A1] The invention relates to a counter-electrode arrangement (14) that, e.g. can be used when coating and removing coatings from turbine blades, and to a method for the operation thereof. The counter-electrode arrangement comprises a reference electrode arrangement that is connected to the counter-electrode (15) in an electrically non-conductive manner via contact elements (17). During the treatment process, a balanced potential over the surface to be treated is created by adapting the reference electrode arrangement, which has individual electrodes (18), to a surface to be treated. In a method for operating the counter-electrode arrangement, a measuring current can be applied to this arrangement in a first step for creating a balanced potential. The individual electrodes (18) of the reference electrode arrangement can be separately contacted in order to determine the respective local potential on the surface of the component to be treated. The counter-electrodes can be adjusted so that a balanced potential prevails on the individual electrodes. During the subsequent treatment of the workpiece, the individual electrodes are interconnected in parallel and used as a reference electrode for maintaining a required treatment potential.
