| 摘要 |
The present invention relates to a method of electrochemical polishing of surfaces of cobalt or cobalt alloys. It employs an electrolyte comprising glycolic acid and at least one alkane-sulfonic acid with an alkyl residue that has 1 to 3 carbon atoms. This electrolyte is also one aspect of the present invention. In one embodiment, at least one alkane-sulfonic acid comprises methane-sulfonic acid. The electrolyte and the method using this electrolyte are suitable in particular for surfaces of cobalt or cobalt alloys, including cobalt-chromium alloys such as stellite.
