Abstract

Die vorliegende Erfindung betrifft ein Verfahren zum elektrochemischen Polieren von Oberflächen aus Kobalt oder Kobaltlegierungen. Dabei wird ein Elektrolyt verwendet, der Glykolsäure und mindestens eine Alkansulfonsäure mit einem Alkylrest, der 1 bis 3 Kohlenstoffatome aufweist, umfasst. Dieser Elektrolyt ist ebenfalls ein Aspekt der vorliegenden Erfindung. In einer Ausführungsform umfasst die mindestens eine Alkansulfonsäure Methansulfonsäure. Der Elektrolyt und das Verfahren unter Verwendung dieses Elektrolyten eignen sich besonders für Oberflächen aus Kobalt oder Kobaltlegierungen, darunter Kobalt-Chrom-Legierungen wie etwa Stellit.The present invention relates to a process for the electrochemical polishing of surfaces of cobalt or cobalt alloys. In this case, an electrolyte is used which comprises glycolic acid and at least one alkanesulfonic acid having an alkyl radical having 1 to 3 carbon atoms. This electrolyte is also an aspect of the present invention. In one embodiment, the at least one alkanesulfonic acid comprises methanesulfonic acid. The electrolyte and method using this electrolyte are particularly useful for surfaces of cobalt or cobalt alloys, including cobalt-chromium alloys such as stellite.
