Abstract

Die vorliegende Erfindung betrifft ein Verfahren zum Elektropolieren von Oberflächen von Metallen und Metalllegierungen. Dieses Verfahren zeichnet sich insbesondere durch seine Anwendbarkeit auf ein breites Spektrum an Metallen aus. So eignet es sich zum Elektropolieren von Metalloberflächen, die aus Eisen, Wolfram, Magnesium, Aluminium oder einer Legierung dieser Metalle bestehen. Der dabei verwendete Elektrolyt umfasst Methansulfonsäure sowie mindestens eine alkoholische Verbindung die ausgewählt ist aus aliphatischen Diolen der allgemeinen Formel CnH2n(OH)2 mit n=2-6 und alicyclischen Alkoholen der allgemeinen Formel CmH2m-1OH mit m=5-8.
