Definitions
- DE 40 32 862 A1 describes a method for pretreating metallic surfaces known for thermal spray coatings, in which a constant on a component surface Water drop jet with a pressure of 2500 to 3500 bar hits as controlled erosion; To increase the erosive effect, solid particles can be added to the water as additives will.
- the object of the invention is to use a method for pretreatment Specify metallic surfaces for reactivable electrodes, in which an enlarged Surface can be created and possibly firmly adhering local contaminants, or Remove residual coatings and passive layers and, if necessary, the surface roughen for the coating process.
- the electrode substrate as well as inside already existing micro-structures or roughness of the substrate are unfavorable Case remain.
- a major advantage is the fact that minimal changes in pressure and Nozzle system, the possibility exists of cutting already coated anodes without heat input, which leads to a deactivation and deterioration of the quality of the electrode in the Edge area could result.

Description
Claims (3)
- Verwendung eines Verfahrens der Vorbereitung des Beschichtungsprozesses von reaktivierbaren Elektroden für elektrolytische Zwecke, deren Oberfläche eine Anfangsrauhigkeit aufweist bei dem ein Hochdruck-Fluidstrahl aus einer Düse auf die zu beschichtende metallische Elektrodenoberfläche auftritt, wobei der Fluidstrahl mit einem Druck von 1000 bis 4000 bar aus einer Düse austritt, zum Entfernen einer auf der Oberfläche befindlichen Beschichtung ohne Veränderung der bestehenden Oberflächenstruktur.
- Verwendung des Verfahrens nach Anspruch 1, wobei der Hochdruck-Fluidstrahl unter einem Winkel im Bereich von 10 bis 90° auf die Elektroden-Oberfläche auftrifft.
- Verwendung des Verfahrens nach Anspruch 1 oder 2 zur zusätzlichen Aufrauhung der zu beschichtenden Oberfläche.
