Ansatz zur Bewertung der Kühl- und Schmiereigenschaften kryogener Minimalmengenschmierungen

Abstract

Abstract Cryogenic minimum quantity lubrication systems (MQL) combine the high cooling effect of cryogenic media and the resource-efficient lubricating effect of an MQL. However, for efficient use, the cooling and lubrication properties must be precisely matched to the respective application and the load case that occurs. This article presents a tribological approach that enables the quantification of the coefficient of friction and the thermal load in frictional contact. This has shown that the use of a cryogenic MQL can significantly reduce both friction and the temperatures that occur.
