Abstract (en)
[origin: WO2009100745A1] The invention relates to a method for producing a component for a heat engine, especially for producing a component for a turbine, a compressor or an expander, according to which a blank of the component is machined by erosion at least in sections, and the surface produced by erosion is finished by barrel polishing and/or electropolishing in such a way that the recast layer created by the erosion is completely removed at least in sections. The invention also relates to a component for a heat engine, produced by means of said method.
