Evaluation and analysis of wear in progressive cavity pumps
… upon the conditions within each individual tribological system. In order to improve or optimise the wear life of a system, it is first vital to understand the complexity of the mechanisms that generate the material loss. This thesis achieves this goal, with specific reference to a pumping …

Grundlagen für das schmiermittelreduzierte Tribosystem bei der Kaltumformung des Einsatzstahles 16 MnCr 5
… between workpiece and tool during forming, the tribological loads on the tools are high. In order to reach an economical tool life, tool wear has to be reduced. In order to reach this goal, a pretreatment of the workpieces and highly additived lubricants are used in cold forming. This leads to …

Numerical Simulation of Contacts Working Under Mixed Lubricating Conditions
… ML region when simulating the behaviour of the tribological system. A substantial aspect of the ML regime is the asperity-asperity interface, whose tribological performance is significantly influenced by contact mechanisms, flash temperature and tribo-chemistry reactions. However, in this study, …

Life Cycle Assessment der alterungsbedingten Umweltverträglichkeit biogener Hydraulik-Schmierstoffe
… water". During storage at room temperature and tribological application, occurring chemical and toxicological changes take no account in the classification of lubricants until now. However, the ageing and oxidation stability gets increasing importance, since it determines the service life of …
