Abstract

A metal surface is prepared by erosion, being blasted by means of a high pressure fluid jet. The metal, after coating with a further metal layer, will become an electrode of high dimensional stability, to be used in electrolytic processes. The outer surface is reactive, or can be activated. The impact of the jet removes foreign matter and any clinging remains of a previous coating, thanks to its high pressure, 1000 to 4000 bar, directed from a nozzle and impinging on the surface at an angle between 10 to 90 degrees .
