Plenary Talks

Andreas PAUSCHITZ, ÖTG-President
Opening and greetings
Hannes HICK, TU Graz, Institute of Machine Components and Methods of Development, Austria
Systems engineering for model-based tribological development of electric vehicle drives
  • From viewing and modeling of the system “vehicle” to the “powertrain” subsystem, up to the integrated implementation of the electric motor and transmission.
Markus VARGA, AC2T research GmbH, Austria
Exploring dynamic effects of tribosystems with high sophisticated measurement equipment
  • New generation of measurement equipment, including high-speed imaging, thermography, and frequency analysis via a 3D vibrometer was used to analyse high-speed tribological effects.
Josef BRENNER, AC2T research GmbH, Austria
Synchrotron-supported tribology: In-situ experiments on large-scale research facility
  • With a specially designed in-situ tribometer, investigations have been performed in an X-ray diffraction Synchrotron station. Selected results are highlighted within this talk.
Carsten GACHOT, TU Wien, Institute of Engineering Design and Product Development, Austria
The fascinating world of 2D Materials – How novel MXenes push the limits in Tribology
  • MXenes and in-situ formed transition metal dichalcogenide films are discussed regarding friction and wear performance and aspects of sustainability and resource-efficiency.
Nicole DÖRR, AC2T research GmbH, Austria
Added value of mass spectrometry for research in tribology
  • It is shown how mass spectrometry (MS) provides the knowledge of lubricant chemistry, in particular lubricant condition, to understand lubricant performance.

11:45 Break

Christoph J. ROHBOGNER, OELCHECK GmbH, Brannenburg, Germany
Improvement of the CO2 balance of FAME (B100) operated trucks
  • Systematically performed oil analysis of trucks are presented which aimed to extend the oil change intervals and therefore achieve maximum lubricant life.
Krisztian DUBEK, AC2T research GmbH, Austria
Development environment of sensor systems for lubricant condition monitoring
  • A sensor system for water detection in lubricated wagon components is presented. Focus is put on the monitoring of water in grease-lubricated axle bearings using a humidity sensor.
Stephen R. BEWSHER, AVL List GmbH, Graz, Austria
Simulating the tribological performance of new water-based and mineral-oil-based lubricants for a journal bearing within an electrified powertrain
  • Simulation results of the tribological performance of a journal bearing with a water-based lubricant operating in the hydrodynamic and mixed lubrication regimes up to 10,000 rpm are presented.
Pia PFEIFFER, TU Wien, Institute of Statistics and Mathematical Methods in Economics, Austria
Prediction of engine oil degradation based on FTIR spectroscopic data
  • By means of weighted LASSO regression, a statistical approach and domain experts’ knowledge are combined to derive a quantitative relation between different degradation pathways in engine oils.

14:20 Break

Florian SOBIECZKY, Software Competence Center Hagenberg GmbH, Hagenberg, Austria
Comparing maintenance strategies for small and medium sized enterprises
  • Artificial intelligence shows promising results for the use in predictive maintenance. In this work new methods are compared, especially to aid SMEs in their maintenance of tribological components.
Andreas BLUTMAGER, Voith Austria GmbH, Wimpassing, Austria
High-end cemented carbide coatings for the toughest demands in the paper industry
  • Different WC-based HVOF coatings were characterized with focus on paper industry, and the results are discussed regarding WC particle size, metal matrix, degree of sintering and density.
Franz RAUFER, AC2T research GmbH, Wiener Neustadt, Austria
Model test bench for switching contacts in e-mobility
  • A novel model test bench for electrical switching contacts is presented, enabling the characterization of performance parameters like arc wear.
Alexander PÖLLINGER, Leobersdorfer Maschinenfabrik GmbH, Leobersdorf, Austria
High-strength polymers for dry-running hydrogen compressors
  • Novel polyimide compound materials are presented, exhibiting high strength, high stiffness, and low friction properties in dry-running hydrogen compressor applications.

16:00 Break

Matthias FREISINGER, AC2T research GmbH, Wiener Neustadt, Austria
History-dependent microstructure on railway wheels – Lab imitation by combined mechanical and thermal loadings
  • A combination of twin disc tribotests and laser treatments was performed, and the resulted microstruc¬ture is presented based on detailed microscopic analysis and a novel micro-mechanical testing approach.
Igor VELKAVRH, V-Research GmbH, Dornbirn, Austria
Tribological behavior of industrial sliding materials in dry contact against Cr-based coatings
  • SRV tribotests were performed at enhanced temperatures with different coatings, and gained results are discussed regarding wear, sticking and sliding friction, and contact temperature.
Martin JECH, AC2T research GmbH, Linz, Austria
Critical wear conditions for DLC coatings
  • A methodology is presented to differentiate mild and severe wear of Diamond-like carbon (DLC) coatings and subsequently evaluate various DLC coatings with respect to their lifetime in applications.
Nicole Dörr, ÖTG Vice President
