摘要： Prior art protective layers can exercise their protecting function because they are depleted in a specific element which forms a protective oxide, or which is used as sacrificial material. When said material has been consumed, the protecting function can no longer be provided. The invention is characterized in that it consists in using powder particles comprising a reserve of the consumed material, which is delivered in delayed manner. Therefor, the material is enclosed in an envelope (4).

摘要： According to prior art, electrolytic methods are used to treat large external surfaces. The invention relates to a method for internally coating the through-holes (7, 7', 7'', 7''', 7'''') of a wall (4), according to which the electrolyte (28) flows through the through-hole (7, 7', 7'', 7''', 7'''') during the treatment and deposits material on the respective inner surface (8, 8', 8'', 8''', 8''''), a single electrode (19) being used for at least two through-holes (7, 7', 7'', 7''', 7'''').

摘要： The invention relates to a method for electrochemical coating, whereby a substrate (14) is subjected to a magnetic field (23) during the layer building process and an electrochemical coating unit. According to the invention, the magnetic field (23) is generated on the surface (21) of the substrate (14) for coating with a locally changing field strength distribution H(x), whereupon electrical field lines (24) in the electrolyte are concentrated in the regions of high magnetic field strength. The layer growth of a layer (22) is increased in these regions, which results, for example, in production of a corrugated profile (27) without subsequent machining steps. Said corrugated surfaces with suitable dimensions advantageously reduce flow resistance of the layer surfaces (27), as a result of which said surfaces are suitable, for example, for flow-optimised turbine blades.
