Tribology research minus the automotive IC engine

The Jost Report resulted in establishment of UK tribology centres focused on nuclear energy, steel production, and friction and wear in plant and machinery. Their primary functions completed, most of these centres have somewhat faded from view.

Automotive tribology only really took off during the 1980s, resulting in the transfer of many tribologists from academe to industry; whole departments were stripped away from universities, by companies able to pay good salaries and with large budgets to equip laboratories. Since then, the automotive internal combustion engine and associated materials, fuels, lubricants and lubricant additives, have dominated tribological research, but that era is demonstrably coming to an end. What happens when the automotive IC engine goes the same way as the steam engine or the fax machine?

At Phoenix Tribology, we have seen a dramatic shift away from our long-term dependence on customers with interests in IC engine tribology; so who are our customers now and what are the tribological problems they are hoping to address?

Presenter: George Plint, Phoenix Tribology Ltd.
In 1983, Dr Michael Plint and Professor Alastair Cameron, (late of Imperial College, London) had the idea of establishing a business based on their research work in the field of tribology. I gave up a well-paid and secure job as an army engineer, to join the embryonic company, Cameron Plint Tribology Ltd, as its first Managing Director. Over the next few years, I fulfilled the combined role of design engineer, tribology researcher and sales and marketing manager.
In 1987, I took over as managing director of Plint and Partners Ltd, a company specialising in engine, transmission and production line test rigs. By the turn of the century, the market for this type of equipment was in steep decline and restructuring of the business proved necessary. Plint and Partners Ltd was wound up in 2002 and with my then business partner, David Harris, we acquired the intellectual property of company’s tribology division. The establishment of Phoenix Tribology Ltd effectively resurrected the original, independent, tribology business of Cameron-Plint Tribology Ltd.

In 2017 I was awarded the Tribology Trust Silver Medal, allegedly for a sustained contribution to the science and technology of Tribology. The Medal is award by the Tribology Trust, which is administered by the Institution of Mechanical Engineers, London. The Awards Committee comprises representatives from the Institution of Mechanical Engineers, the Institution of Engineering and Technology, the Institute of Materials, Minerals and Mining, the Royal Aeronautical Society and the UK Department for Business, Energy and Industrial Strategy.

Presenters Bio: Dr. Peter Lee
After leaving school, Dr. Peter Lee qualified and worked as a motor vehicle technician for four years before attending university.  At the University of Leeds in the UK, he studied for an automotive engineering degree and was then asked by Shell and Infineum to study for a PhD in the field of automotive tribology.  After receiving his PhD in 2006, Peter was awarded a five-year Royal Academy of Engineering Fellowship to continue his research in automotive tribology.  In 2011 he moved from the UK to San Antonio, Texas, where he established the Tribology Research and Evaluations Laboratory at Southwest Research Institute (SwRI).  Initially being automotive focused, the labs are now multidisciplinary and have tested for all clientele from deep sea to deep space. Peter is part of the Advanced Fluids for Electrified Vehicles Consortium recently started at SwRI.

Ensuring a sustainable chemical supply chain through the constant of change
November 11, 2024

There has been a rapid increase in globalization since the late 1970’s and especially since the turn of this century. It has enabled the chemical supply chain – and indeed all supply chains – to develop and evolve to become highly integrated and efficient, allowing the swift and economical movement of goods, services, and people across the world.

The chemical supply chain is one of the most complex in the world. It is truly global, with raw materials and finished products, including hazardous materials, moving between or through multiple countries. However, in recent years it has faced unprecedented challenges and disruption with far reaching consequences.


Presenter: Tim Doggett, Chemical Business Association
Tim Doggett, CEO of the Chemical Business Association will present on key factors and considerations, and some of the actions and initiatives being taken to ensure a sustainable chemical supply chain.



Oil Drain Levels

October 9, 2024

Oil Change Intervals: How accurate are the oil life indicators on modern vehicles? Some people still say every 3 months or 3,000 miles (regardless of what the oil life indicator says), but some oils claim 25,000 mile oil change intervals, which is much further than what the oil life indicators allow. These consumer perceptions and brand positions create a lot of confusion in the marketplace. So what does the data say? Let’s take some real world used oil analysis results and get to an answer.

PFAS: Guidance on How to Deal with a Potential Health Hazard
August 21, 2024


PFAS, the acronym for per-and polyfluorinated alkyl substances, have come under regulatory scrutiny due to real and potential health & safety concerns. The purpose of this Industrial Insight program is to provide basic information on PFAS.

Included will be an update on what is known about the health & safety problems associated with exposure, what is the main source of exposure, water, regulations that have been implemented to limit PFAS exposure, and what should be done at the workplace to minimize exposure. In the latter case, attendees will be urged to check the raw materials used in their plants and work with their suppliers to make sure no PFAS containing products are being used, and request alternatives that are PFAS-free.

An update will be provided on the three main issues concerning how to deal with PFAS: detection, isolation and destruction. The presence of an estimated 15,000 PFAS in the environment makes it more difficult to understand which PFAS are hazardous. An assessment will be made that isolation techniques are significantly ahead of the other two issues making it difficult to manage PFAS contamination.

The two panelists will take time to answer attendee questions about PFAS and point out that further information will be provided in the September 2024 issue of TLT.

Taming Friction: The Potential of Ionic Liquids in Tribology
July 11, 2024

Ionic liquids (ILs) have gained considerable attention owing to their unique and tunable physico-chemical properties (e.g., low vapor pressure, high thermal stability, low flammability, good ionic conductivity, wide electrochemical stability window), which have made them useful for a range of applications, including energy storage, catalysis, and chemical processing. ILs are particularly attractive in lubrication, since their properties make them suitable for reducing friction and/or wear in a variety of applications, such as automotive, manufacturing, aerospace, and semiconductor devices


In this talk, I will provide an overview of the potential use of ILs in tribology with a particular focus on their promising properties when used in the boundary lubrication regime, i.e., when applied loads are too high and sliding speeds are too low for a full fluid film to be maintained. Under these conditions, the interfacial structure and properties of ILs start to deviate from the ones in their bulk phase. Specifically, the strong spatial confinement of ILs between sliding surfaces promotes the interaction between the IL molecules and the confining surfaces as well as between the functional groups within the ions. These strong interactions under confinement affect the behaviors of the ILs in terms of phase transition, ion mobility, and chemical reactivity. As the properties and dynamic evolution of IL/solid interfaces under tribological applications play a critical role in determining the lubrication performance in the boundary lubrication regime, I will discuss in detail the current state-of-the-art concerning the interfacial phenomena occurring between IL and solid materials under confinement using the results of our research group as particular example. I will then highlight the emerging knowledge on the interrelationship between the molecular structure of ILs and their behavior at sliding interfaces.

Finally, I will discuss the potential application of ILs in future technologies enabled by research efforts aiming to overcome three major challenges for ILs, namely their sensitivity to ambient moisture, corrosivity and toxicity, and high-cost.

Technology Evolution in the Transportation Industry and the Need for Enhanced Testing

Continuous evolving electrified systems within the transportation industry have occurred at an accelerated pace. Aerospace and automotive manufacturers are tasked to significantly reduce carbon emissions. Various designs that are being developed have both strengths and weaknesses. Proper lubrication and cooling have been key to ensure the proper performance of any vehicle. High-speed electric vehicle systems are performing with electrified system, causing significant wear and pitting conditions. In some designs, the electric motor and its corresponding electronics are in contact with lubricant or its ensuing vapor. This raises concerns regarding copper corrosion and the potential formation of conductive deposits on critical parts. Other areas require immense cooling systems that have a propensity to cause other potential failures. There are hybrid systems that incorporate both technologies, but some are attempting single source coolant and lubrications systems.
In this presentation, we will review tools that are available or being developed to evaluate lubricant performance. Subsequent shortcomings to access lubricant suitability for electrified drivetrains will also be demonstrated. Various versions of test methods are already in use within the automotive industry, but some of these tests are not standardized or widely available. We will discuss the collaborative efforts to standardize these test methods and make them widely available.

Varnish MythBusters

Lube oil varnish has been an issue plaguing the users of rotating equipment and hydraulic systems for years. Most people understand that varnish is comprised of oil-derived deposits, however it is amazing how little is still understood about varnish. Even more damaging are myths about varnish, that are not based on science, as financial decisions are made based on this inaccurate information. This event will examine several myths about varnish and discuss whether they are in fact accurate or if the myth is “busted”. Half of the session is also dedicated to audience questions. Do you have a question about varnish? Here’s your chance to talk with the experts to get an answer…based in science.

Post Machining Cleaning - How to Pick the Right Surfactant For the Job

With the hundreds of available surfactants on the market to incorporate into a metal cleaning formulation, the task of picking the correct surfactant can be daunting. Determining whether your formulation requires emulsification or rejection of foreign oil is critical for selecting the proper surfactant in a cleaning formulation. Understanding surfactant performance with various soil types, metal types, and pH stability will help the end-user achieve their desired cleanliness. The backbone of the surfactant chemistry will determine the functionality of the surfactant and its application performance. This paper will define trends associated with different surfactant chemistries and how to apply this theory to developing a cleaning formulation.

Simulation of noise and vibration of systems with real rolling bearings

Noise and vibration (NVH) is becoming a more emphasized performance criteria not only for single components like rolling bearings, but also for complex systems like drive trains or gearboxes. For life and friction assessment of these systems ideal component geometries are typically used and sufficient for the design. For NVH, tolerances of the components and their interaction is much more important and cannot be neglected. For some issues single component simulations are sufficient to optimize the design for NVH. The interaction of components, impact on system level (i.e., perception of the customer) can only be assessed by system investigations. Due to the huge set of geometry parameters, tolerances and operating conditions, simulation is the only efficient way to the optimum design. In this session Dr. Grillenberger will show the simulation approaches on NVH design for single bearings and complete rotatory systems. 

Presenter: Dr. Hannes Grillenberger

Improved Throughput and Analysis of Scratch Test Results via Automation and Machine Learning The STLE Early Career Research Poster Award Winner

A data analysis automation interface that incorporates machine learning (ML) has been developed to improve productivity, efficiency, and consistency in identifying and defining critical load values (or other values associated with optically identifiable characteristics) of a coating when a scratch test is performed. An optical examination of the scratch by a human operator is currently used to determine where this value occurs. However, the vagueness of the standard has led to varying interpretations and nonuniform usage by different operators at different laboratories where the test is implemented, resulting in multiple definitions of the desired parameter. Using a standard set of training and validation images to create the dataset, the critical load can be identified consistently amongst different laboratories using the automation interface without requiring the training of human operators. When the model was used in conjunction with an instrument manufacturer’s scratch test software, the model produced accurate and repeatable results and defined LC2 values in as little as half of the time compared to a human operator. When combined with a program that automates other aspects of the scratch testing process usually conducted by a human operator, scratch testing and analysis can occur with little to no intervention from a human beyond initial setup and frees them to complete other work in the lab.

Atomistic Understanding of Grease Tribolayers on Bearings Surfaces 

Grease lubricated bearings are commonly utilized in the industrial applications like construction and mining, cement, steel and aluminum mills, food machinery, paper and pulp, and wind turbines. Greases and thickener chemistries have a big impact on the bearing lubrication. This study investigates morphological and compositional characteristics of grease-generated tribolayers at an atomistic level. Tribolayers from lithium-based and polyurea based grease thickeners formed on 52100 bearing steel were investigated using atom probe tomography and transmission electron microscopy. The results reveal formation of multilayer chemistries resulting from tribochemical reactions between the steel interfaces, featuring evidence of oxygen diffusion, air pockets via mechanical deformation, and metallic clusters. The results indicate that the polyurea grease tribofilm’s amorphous nature, size of the air pockets, and top FeS layer provided exceptional friction and wear properties compared with tribofilm generated using greases with lithium complex thickeners.

Keys to Implementing a Successful In-Service Grease Analysis Program

New grease testing has been around nearly as long as modern greases have been manufactured to evaluate manufactured greases' performance and quality.  Standards have been introduced to ensure accurate and representative sampling, along with a broad test slate to help make decisions to optimize grease life and enhance asset performance. More recently, methods have been developed that focus on the unique challenges of taking representative samples and analyzing smaller grease volumes available when testing in-service greases. This testing allows us to evaluate the wear condition of the asset, along with the presence of contaminants and the physical condition of the grease. This presentation will present the steps necessary to set up a successful in-service grease analysis program that can help asset owners meet reliability goals, extend the grease and grease components' life, and optimize the grease's sustainability lubricated components.

Wind Turbine Lubrication Challenges


Energy in the U.S. has surpassed 120 GW of installed capacity and continues to be a leading source of new generation additions. In 2020, wind power contributed the most energy compared to all other sources (solar, natural gas, etc.) at 18.5 GW. However, wind turbines are commonly plagued by reliability issues, including drivetrain components that experience unusually short lives. This is due to numerous reasons, many of which stem from lubrication issues. The replacement of these components comes at a very high cost due to these turbines' location and size. Furthermore, the industry is progressing to larger turbines, increasing power ranges from 0.75- 2.5 MW to 4-10 MW capacity, as well as moving turbine locations offshore, where access to the turbines becomes more costly, and environmental concerns of possible lubricant leakages arise.
