News 42 Tribologie + Schmierungstechnik · volume 71 · issue 2/ 2024 This year we are celebrating the 65 th annual conference of the German Society for Tribology GfT. Reason enough to look back, to reassure ourselves of our current status and to look ahead to future developments: because for a society like ours, 65 years is not the time to think about retirement or even just ‘shifting down a gear’, but on the contrary: the best is yet to come, tribology has never been as valuable as it is today. So we are celebrating an anniversary: well, we want to do justice to this with this year’s programme and offer some special ‘treats’, for example a plenary lecture on ‘The history of tribology in Germany and future prospects’. So let’s try to define the position of tribology in the 65 th year of the GfT: Won’t tribological research come to an ‘end’ at some point? Don’t we have to constantly ask ourselves the self-critical question of the effort involved in any further progress? Hermann Heinrich Gossen (1810 - 1858) was a German lawyer and economist who, as part of his work on consumption theory, developed two rules that became known as Gossen’s Laws. In a publication from 1854, he formulated the first ‘law of diminishing marginal utility’ as follows: ‘The size of one and the same pleasure, if we continue to prepare the pleasure without interruption, decreases continuously until satiation finally occurs.’ What does Gossen mean by ‘pleasure’? Applied to tribology, we can replace ‘pleasure’ with ‘friction reduction’, for example: ‘If we continue to reduce friction without interruption, the amount of friction reduction decreases continuously until saturation finally occurs.’ In this context, saturation means that the effort becomes greater than the benefit. Yes, of course we will always have to base our findings on the costs! Changes in the ‘general weather situation’ must also be soberly recognised: In recent years, efforts to reduce CO 2 emissions in motor vehicles have been a key driver of tribology research - the threat of CO 2 fines in conjunction with mandatory testing programmes (NEDC, WLTP, etc.) have been at the forefront. Due to electrification and changes in the political framework conditions, mobile drives are no longer at the centre of tribological interest. This makes it all the more important and promising to transfer the findings and improvements developed for mobile systems to other industrial systems: Another increasing driver of tribology is the reduction of wear in technical systems - the service life of devices, machines and systems is becoming significantly more important. In this context, we would like to draw your at- Gesellschaft für Tribologie Foreword: 65 th annual conference of the German Society for Tribology tention to the recently published GfT position paper on white etching cracks (WEC): In a joint effort of 25 representatives from research and industry, a comprehensive overview of damage patterns, development hypotheses, influencing factors, risk assessment and recommendations for action of the rolling bearing damage pattern WEC was compiled in a total of 42 meetings in the period from 2021 to the end of 2023. There is also a lot of positive news to report from other GfT working groups. The Training and Further Education Working Group has launched a new series of seminars under the overall management of Prof. Bartel and in cooperation with the Research Association for Drive Technology (FVA): The first seminar on plain bearing lubrication was successfully held in May 2024. Further events on the basics of tribology, gearbox lubrication and rolling bearing lubrication are in preparation. The Regional Working Groups in Munich, Rhine-Neckar and Berlin-Brandenburg have continued or resumed their regular lecture events with renewed vigour. One new feature is that the events are being offered in a hybrid format and therefore also offer supra-regional participation. If you say three, you have to say four: Following our 3 rd GfT study ‘Effects of tribology on CO 2 emissions in the use phase of products - contributions of tribology to defossilisation’, the Climate Protection & Sustainability Working Group has started work on a fourth study, which will include concrete examples of tribological contributions to friction reduction and defossilisation, in short: to avoided emissions. The Public Relations Working Group has launched further important initiatives to better present the GfT, its tasks and its benefits in the modern media world. The GfT’s presence in the social media is being expanded in order to reach young tribologists in particular on today’s relevant information channels. At this point, we would also like to mention that we have started regular dialogue contacts with the Austrian Tribological Society (OeTG) and SwissTribology. The Young Tribologists Working Group will be holding the 7 th Young Tribological Researcher Symposium on 22 and 23 July 2024 at the Friedrich-Alexander University Erlangen-Nuremberg. This year in particular, the GfT Annual Conference aims to offer you plenty of inspiration for new tribological approaches and solutions. In addition to already established News 43 Tribologie + Schmierungstechnik · volume 71 · issue 2/ 2024 In November, 65 years ago, the Gesellschaft für Schmiertechnik (GST), the predecessor organization of the GfT, was founded. Since annual conferences on the topics of friction, lubrication and wear have been held regularly from the very beginning, the German Tribology Conference can also celebrate its 65 th anniversary this autumn. On this occasion, the plenary event will begin with a look back not only at the history of GfT, but will also highlight the milestones of tribological re- Gesellschaft für Tribologie 65 th German Tribology Conference 2024 Some highlights of the 65 th Tribology Conference: Plenary Session: Monday, 23.09.2024: • 65 Years of GfT - History of Tribology in Germany and Future Prospects of the Field • C. Gachot, Vienna University of Technology: Perfect Friction in 2D - Solid Lubrication with MXenes and Transition Metal Carbo Chalcogenides • M. Marian, Leibniz Universität Hannover/ Pontificia Universidad Católica de Chile: AI think, therefore AI am a Tribologist • M. Dienwiebel, Karlsruhe Institute of Technology KIT / Fraunhofer IWM: Verständnis tribologischer Mechanismen durch Kombination multiskaliger Experimente und Simulation (Understanding tribological mechanisms by combining multiscale experiments and simulation) search in Germany over several centuries. In interviews and other contributions, however, the present and the outlook on future challenges are not neglected. As every year, the current state of the art of tribological research and development, mainly in Germanspeaking countries, is reflected by the program of the conference, which includes more than 70 lectures from almost all areas of tribology. special sessions, e.g. on the Research Field of Tribology, it includes many exciting contributions, poster and technical exhibitions and, of course, stimulating discussions ‘in between’ in the circle of the GfT family! Finally - after the GfT conference is before the Nextlub: The international tribology conference Nextlub will take place for the second time - as a joint format of Uniti, FVA and GfT - from 22 to 23 January 2025 in Leipzig. We can already reveal that there will once again be an extremely interesting and varied programme! But first: See you again in Göttingen! Rolf Luther Chairman of the Executive Board of GfT Dr. Thomas Gradt, Managing Director of GfT News 44 Tribologie + Schmierungstechnik · volume 71 · issue 2/ 2024 Wednesday, 25.09.2024: • Matthias Scherge, Fraunhofer KIT: Bowling, the Tribological Eldorado Closing ceremony: • Andreas Krüger, Fuchs Lubricants Germany: The Tribological Possibilities in the Interior of an Automobile Special Sessions: In 2024, the progress in the DFG priority program “Fluid-Free Lubrication Systems with High Mechanical Loads” will again be presented in a full-day session. The research field “Tribology” is also represented with its own session. The research field is funded as a part of the energy research programme of the Federal Ministry for Economic Affairs and Climate Action and thus contributes to the energy transition in Germany. The following awards and prizes will be presented during the conference: • Georg-Vogelpohl-Ehrenzeichen for personalities who have rendered outstanding services to tribology • Sponsorship awards for the best submitted bachelor’s, master’s and doctoral theses • The prize “Tribologie ist überall” (Tribolgy is everywhere) for submissions tribological everyday phenomena (donated by Werner Stehr) After the success of the last years, we can also look forward to a “Triboslam” again. The conference will again include a poster and a trade exhibition in the foyer of the conference hotel. There are still free places available for the latter. You can find out the prices and conditions at the GfT office.

KG in Burghausen. Twenty participants from research and industry gathered to use the event as a forum for discussing research and application topics in tribology. Engaging interdisciplinary presentations on ‘Sustainable Fuels and Lubricants in the Context of the Energy Transition’ encouraged lively exchanges and discussions among the attendees. We are delighted with the success of the event and extend our gratitude to all participants for their enthusiastic interest and active engagement in the discussions. Details about the next meeting of the GfT Arbeitskreis München will be announced in due course. Gesellschaft für Tribologie 7 th GfT-Kolloquium Arbeitskreis München News 46 Tribologie + Schmierungstechnik · volume 71 · issue 2/ 2024 The presentation “Efficient and sustainable machine operation with the help of lubricant analyses” clearly showed the importance of oil analysis for sustainable machine and plant operation. The first part of the presentation focused on typical characteristic values for various oils and applications, as routinely carried out and evaluated by Oelcheck. Mr. Mitterer then used illustrative practical examples to show that regular oil analysis is not only important from an environmental point of view, but that there are also financial benefits for operators of vehicle fleets, wind turbines or paper machines if, for example, oil change intervals can be extended without risk. After an extensive discussion and question and answer session, the participants continued to talk shop in a relaxed atmosphere over drinks and pretzels.
