Abstract

The invention relates to a method for electropolishing light metal alloy surfaces containing a portion of silicon greater than 3 wt. % in an electrolyte which essentially contains phosphoric acid. The surface is anodically connected and the electrolyte contains a fluoride and iron (III) ions. The invention also relates to an electrolyte used for carrying out said method.
