Beschreibung
Zusammenfassung:	The present invention relates to a method for mechanically working of cobalt-containing metals or performing metalworking with a tool made of a metal containing cobalt. The method is carried out in the presence of an aqueous cooling lubricant containing a combination of an alkanolamine, a mono- or diphosphate ester and a mono- or dicarboxylic acid. The combination is capable of reducing both the release of cobalt ions and the corrosion of iron. In addition it also contributes essentially to the lubrication.
