Abstract (en)
[origin: WO2006032562A1] 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.
