Nachhaltige Schmierstoff-Additive auf Basis von Mikroalgen in der Umformung und Zerspanung. Teil 1

Microalgae offer a very good basis for use as a sustainable source of raw materials for technical applications, since a large number of suitable chemical compounds can be obtained from them. In the research project ALBINA (German acronym for: Algae-based – Biological – Renewable), components of micro-algae have been processed in order to test them as additives for lubricant applications. The obtained results of the technical tests in machining and forming show a great potential of the algae extracts with regard to their use as EP/AW additives. Under the premise of certain process parameters, in metal cutting it is possible to achieve an equivalent tool life time compared to conventional additives, when algae substances are used. In metal forming, positive results have been obtained by using algae extracts in the ring compression test and deep drawing process. Part 1 of the publication describes the technical parameters and chemical analyses from the investigations, while Part 2 focuses on the results obtained from the technical tests.
