Send us Fan MailThis podcast episode dives deep into the persistent and often misunderstood issue of micropitting in gears, guided by expert insights from Ben Wainwright. The conversation begins by defining micropitting and examining how it manifests in real-world applications, asking whether it remains a practical concern in modern gear systems and what fundamental factors—such as lambda ratio, surface roughness, and contact conditions—drive its formation. We explore how micropitting should be properly characterized, which surface finishes are most effective at reducing risk, and the complex role lubricants play, including whether antiwear and EP additives mitigate or inadvertently promote damage. The discussion then turns to testing: how micropitting is currently evaluated, whether today’s tests truly reflect field failures, and what an ideal test might look like if designed from first principles. The episode closes with practical guidance for gearbox designers, common misconceptions still seen in industry, trusted rules of thumb, and a forward-looking question on whether micropitting is something we will ultimately engineer out—or simply continue to manage. Our Guest:Benjamin Wainwright completed his studies in mechanical engineering at Imperial college London in 2017.

Send us Fan MailThis month's episode focuses on using friction to help us.  Yes, that's right, embracing the friction that tribologists try to combat.  The focus is of tactile aids that solely rely on physical bumps, lines, and textures are limited in the amount and density of information they can convey due to "tactile clutter" within a small physical space. The lab has found that different surface chemistries alone can create distinct sensations without adding larger scale roughness, and Maryanne's work identifies frictional instabilities as a framework for predicting how different surfaces will feel from each other. This type of analysis and connection between material structure and dynamic friction can help predict how to engineer more advanced materials to expand the types of sensations people can feel, and design more types of tactile aids, such as sensors or medical diagnostics with inherently switchable materials. Our Guests:Maryanne Derkaloustian is a third year PhD candidate at the Department of Materials Science and Engineering at the University of Delaware. She received her BS in Materials Science and Engineering at the University of Illinois at Urbana-Champaign.

Send us Fan MailThe role of tribology in facilitating the move to sustainability does not just involve reducing friction and wear in industrial machinery and automobiles, but also is critical in gaining a better understanding of what we eat and what steps can be taken to improve the availability of healthier foods. This episode focuses on the topic of chocolate and research that is ongoing to better understand how this food is eaten and how tribology is used to better understand this process. A discussion is held with Dr. Siavash Soltanahmadi, Research Fellow at the University of Leeds (UK), who describes ongoing research trying to better understand the process of eating dark chocolate. When eating a piece of chocolate, an enjoyable sensation is felt due to the creamy feel of this food which provides a textural sensation. In discussing the eating of chocolate, a phase transfer takes place as the solid chocolate transitions into a molten fat phase followed by introduction of saliva, leading to the formation of an emulsion as digestion is initiated. Through a series of studies using a tongue-like surface, oral tribology is used to better understand the eating process. From this work, a multiscale tribology-informed smart design of chocolate is proposed that uses a gradient technology to retain the pleasurable eating sensation, but reduces the fat content of chocolate, leading to a healthier food.Contributors: Dr. Neil Canter, STLE Advisor, Technical Programs and Services, Dr. Siavash Soltanahmadi, Research Fellow, University of Leeds, UK For more information on STLE, please visit https://www.stle.org/ If you have an idea for our podcast, or interested in being a guest, please Email STLE Director of Professional Development Robert Morowczynski at [email protected] .   Also, we love your feedback, please take a minute to provide us with your thoughts at Perfecting Motion Podcast Feedback or Email us at [email protected].  

Send us Fan MailTribology, the scientific study of lubrication, friction and wear, is as old as the world itself and can be found in almost every application. The word itself was not entered into the English dictionary until 1966 at the time of The Jost Report. The use of tribology to solve friction and wear problems through the life cycle of a product from manufacture, use and recycling can be used to improve sustainability. This podcast looks at how tribology testing can be used to improve sustainability, and benchtop rigs can be used to scale down full-size application and achieve usable realistic results that can then be scaled back up for real-life applications.Contributors: Dr. Peter Lee, FSTLE, Institute Engineer and Chief Tribologist, Southwest Research Institute, George Plint, Director, Phoenix Tribology Ltd., and Dr. Dirk Drees, CEO, Falex Tribology BelgiumFor more information on STLE, please visit https://www.stle.org/ If you have an idea for our podcast, or interested in being a guest, please Email STLE Director of Professional Development Robert Morowczynski at [email protected] .   Also, we love your feedback, please take a minute to provide us with your thoughts at Perfecting Motion Podcast Feedback or Email us at [email protected].  

Send us Fan MailThe search for finding a way to commercialize vehicles that generate no emissions has led the automotive industry to work with batteries and fuel cells. But another approach is to take the basic internal combustion engine (ICE) and substitute hydrogen as a fuel for both gasoline and diesel fuel. This podcast examines the potential for hydrogen internal combustion engines. In this engine, hydrogen reacts with oxygen in the air as part of a combustion process, but the only byproduct is water. The initial results are quite favorable. Without the use of hydrocarbon fuels, the ICE runs much cleaner and the motor oil used is not impacted. The motor oil looks as pristine as when it was initially put in the engine. There is the potential for the motor oil to last at least 50,000 miles. The conclusion from this podcast is that hydrogen not only has the potential to be a short-term answer to reduce automotive emissions but could also be a long-term solution.Contributors: Dr. Neil Canter, STLE Advisor, Technical Programs and Services, Mike Copeland, Owner and CEO, Arrington PerformanceFor more information on STLE, please visit https://www.stle.org/ If you have an idea for our podcast, or interested in being a guest, please Email STLE Director of Professional Development Robert Morowczynski at [email protected] .   Also, we love your feedback, please take a minute to provide us with your thoughts at Perfecting Motion Podcast Feedback or Email us at [email protected].  

Send us Fan MailNuclear power is emerging as a viable energy generation option that does not release greenhouse gases in contrast to fossil fuel energy sources. While the nuclear power industry has come under scrutiny due to past issues with specific plants, overall, the industry practices excellent safety protocols and nuclear power plants operate in a very safe manner. Currently, nuclear power contributes about 10 percent of global electricity production behind coal, gas, and hydro, according to a 2019 study by the International Energy Agency (IEA). There is interest in bringing on additional nuclear power capacity to assist with reducing greenhouse gas emissions attributed to power generation. This episode includes a discussion with a representative from the nuclear power industry to get an update on whether adding more nuclear power plants is under consideration as an energy generating option. This podcast focuses on the growing interest in using small modular reactors (SMRs), which are downsized versions of existing nuclear power plants that can be designed for operation in specific locations that may be remote or have a specific power requirement that cannot be handled by existing power generation options. Prefabrication of the components used in SMRs is discussed, as this is an advantage in reducing the cost of manufacturing nuclear reactors. Components can be shipped to the location where the SMR will be placed and installed at that point in a similar manner to using Lego bricks. Contributors: Dr. Neil Canter, STLE Advisor, Technical Programs and Services, Robin Manley, Vice President, New Nuclear Power Development, Ontario Power Generation For more information on STLE, please visit https://www.stle.org/ If you have an idea for our podcast, or interested in being a guest, please Email STLE Director of Professional Development Robert Morowczynski at [email protected] .   Also, we love your feedback, please take a minute to provide us with your thoughts at Perfecting Motion Podcast Feedback or Email us at [email protected].
