Design of Catalytically Active Tribomaterials, Coatings, and Additives for More Effective Boundary Lubrication
Erdemir, G. Ramirez, O. Eryilmaz, Argonne National Laboratory, Argonne, IL 60564, USA
We have developed a breed of novel catalytically active materials, coatings, and lubricant additives that can lead to the formation of carbon-rich boundary films affording much superior friction, wear, and scuffing properties to sliding contact interfaces. Specifically, these materials, coatings, and additives comprise catalytically active metallic ingredients with extraordinary responsiveness to the long-chain hydrocarbon molecules of oils especially under the high contract pressure, shear, and flash-heating conditions of sliding contact interfaces. They can also positively interact with the traditional anti-friction and –wear additives whose backbones are also made of hydrocarbons. The resultant boundary films are in a hybrid form and consist not only the conventional P and S-based compounds but also copious amounts of carbon. These catalytically active surfaces and additives are also compatible with other hydrocarbon-based fuels and lubricants including bio-derived fuels and lubricants as well as natural gases (or methane) in which the resulting tribofilms consist of a mixture of tribologically favorable carbon nanostructures like graphene, nano-onions, nanotubes and disordered graphite which are well-known for their exceptional friction and wear properties. Using TEM, UV Raman and TOF-SIMS, we analyze these tribofilms and reveal their structural chemistry, which are responsible for their unusual friction and wear properties.
Greg Croce received his bachelor’s of science degree in chemical engineering and an MBA from the California State Polytechnic University, Pomona. He first worked as an analytical chemist for Weck Laboratories and then a process engineer and manager of engineering for Technip USA/KTI, where he was a combustion engineer, designing fired heaters. In 2000 Croce joined Chevron as a global account manager/OEM service engineer. At Chevron he has held several positions including North American product line specialist, regional sales manager for Techron, base oil optimization specialist, and Product line manager for global marine. In his current role, he manages the heavy duty product line for Chevron globally, including Heavy Duty Engine Oils, Driveline Products, Coolants and Greases. he is also the current President of the Society of Tribologists and Lubrication Engineers (STLE).
Hugh Spikes graduated in Natural Sciences from the University of Cambridge in 1968 and obtained his PhD for research in Tribology from Imperial College in 1972. He is currently Emeritus Professor in the Tribology Group, Mechanical Engineering Department, Imperial College London. Professor Spikes is a Fellow of the Royal Academy of Engineering and also of the Society of STLE and ASME. He has been involved in research in tribology for over forty years and has received a number of recognitions for his research achievements including the ASME Mayo D Hersey Award and the STLE International Award. In 2004 he was awarded the Tribology Trust Tribology Gold Medal, the highest international honour in Tribology. Ten of his research publications have received best paper awards, from STLE, IMechE and ASME. Professor Spikes’ research interests span a wide range of liquid lubrication research, including hydrodynamic, elastohydrodynamic and boundary lubrication. A particular interest has been thin film lubrication and the influence of lubricant composition on the film-forming properties of lubricants and thus on friction and wear performance.

He currently serves as Deputy General Director in Charge of Research & Innovation of Arts et Métiers ParisTech, France. He also chaired the Mechanical Engineering and Manufacturing Research Group (www.lmpf.net). He received his B.Sc. in Physics from the University of Hassan II in 1993 (Casablanca, Morocco), and his Ph.D. in Mechanical Engineering from the Institut National Polytechnique de Lorraine in 1997 at Nancy, France. His research interests include the interface of thermo-mechanics characteristics of material and physics behind the tribological performances of both metallic and composite materials. The research activities carried out within the last decade have engulfed to the problems concerning the tribological characteristics of engineering systems and manufacturing processes. The interests of this approach are in its capability to “bridge the gap” between the traditional approach of academia and the industrial requirements. He has more than 65 papers in JCR referenced international journals and more than 150 publications in international and national conference proceedings. He has been an invited speaker to several conferences and has taught short courses on tribology in the multiscale manufacturing process.
