Andreas PAUSCHITZ, ÖTG-President
Opening and greetings
09:15
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.
09:45
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.
10:15
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.
10:45
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.
11:15
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

13:00
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.
13:20
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.
13:40
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.
14:00
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

14:40
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.
15:00
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.
15:20
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.
15:40
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

16:20
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.
16:40
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.
17:00
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.
