The 25th Leeds-Lyon Symposium on Tribology was held at the Institut des Sciences Appliquées de Lyon, from 8-11th September, 1998. Its central theme was, "Lubrication at the frontier: the role of the interface and surface layers in the thin film and boundary regime". This topic was chosen because it represents an important evolution of the research field.The Symposium opened with a keynote address entitled "Role of surface-anchored polymer chains in polymer friction" which described the processes taking place at the interface between "solid" and "liquid". The keynote address was followed by two invited lectures. Firstly, "Fuel efficient engine oils, additive interactions, boundary friction and wear" presented the industrial point of view on lubricant formulation and engine testing and its evolution. The second lecture was entitled "For establishment of a new EHL theory" and stressed the need to extend the current EHL theory.Beginning in 1974, The Leeds-Lyon Symposia have now covered a wide range of topics. The essential aim each year is to select a topic of current interest to tribologists and to contribute to further the advance of knowledge in selected fields.

This collection of fully peer-reviewed papers were presented at the 26th Leeds-Lyon Tribology Symposium which was held in Leeds, UK, 14-17 September, 1999. The Leeds-Lyon Symposia on Tribology were launched in 1974, and the large number of references to original work published in the Proceedings over many years confirms the quality of the published papers. It also indicates that the volumes have served their purpose and become a recognised feature of the tribological literature.This year''s title is ''Thinning Films and Tribological Interfaces'', and the papers cover practical applications of tribological solutions in a wide range of situations.The evolution of a full peer review process has been evident for a number of years. An important feature of the Leeds-Lyon Symposia is the presentation of current research findings. This remains an essential feature of the meetings, but for the 26th Symposium authors were invited to submit their papers for review a few weeks in advance of the Symposium. This provided an opportunity to discuss recommendations for modifications with the authors.

These papers represent the proceedings from the 29th Leeds-Lyon Symposium on Tribology, ''Tribological Research and Design for Engineering Systems'' which was held in September 2002. Over 130 delegates from 18 countries attended the symposium, and the extensive discussions generated over 150 written questions and responses, which are documented at the end of this proceedings volume.There have been many advances in the field of tribology in recent years, with progress being made in the engineering and interaction of surfaces; micro and nano-tribology; elastohydrodynamics; surface films; surface texture; tribochemistry; wear and life prediction; with both experimental and theoretical contributions. These advances were reviewed, and the impact of this understanding on the fundamentals upon total engineering activity in design, manufacture and machine operation were considered.Readership:Scientists and researchers in the field of tribology.

The 24th Leeds-Lyon Symposium was held in London from 4th-6th September 1997, where it was hosted by the Imperial College of Science, Technology and Medicine.The meeting addressed the topic of "Tribology for Energy Conservation" and attracted a wide range of stimulating papers and speakers. Some 150 delegates from nineteen countries attended and about sixty papers were presented in fifteen sessions. These covered the topics of lubricants, wear, friction reduction, hydrodynamics, elastohydrodynamic lubrication, surface roughness, manufacturing, component life (including condition monitoring), and automotive aspects.

The thirteenth Leeds-Lyon Tribology Symposium was devoted to the topic of Fluid Film Lubrication in celebration of the centenary of the publication of the classical paper by Professor Osborne Reynolds in which he identified the mechanism of hydrodynamic lubrication.These proceedings contain more than seventy papers, written by authors from all over the world, covering the entire spectrum of fluid film lubrication. Of particular interest is the detailed consideration of a wide range of machine elements - bearings, seals, cams, rolling elements, as well as the in-depth, state-of-the-art, analytical contributions.

Many tribologists are today not only explicitly concerned with interface action but also with interface composition. This proceedings volume presents a timely review on topics ranging from interface dynamics to interface elimination, covering all factors such as contact stress fields, interface rheology, and boundary slip, that control the passage from formation to elimination. The volume contains 45 papers divided into 13 sessions, that were presented at the symposium.

On previous occasions each Symposium has focused attention on a current and significant research topic, usually reflecting the interests of the Leeds or Lyon research groups, however this time the main focus was on the vitally important subject of technology transfer, providing the 154 delegates from 21 countries with the rare opportunity to discuss the impact of their studies on machine design.

Mechanics of Coatings was chosen as the topic for the 16th Leeds-Lyon Symposium, as it was decided to be a timely opportunity to bring together experts of many disciplines connected with coatings to find ways of extending the industrial use of these coatings particularly in the field of tribology. The volume contains 51 papers divided into 20 sessions.

Vehicle Tribology was chosen as the topic for the 17th Leeds-Lyon Symposium, as it was decided to be a timely opportunity to bring together experts of many disciplines connected with problems of emissions, particulates and energy efficiency associated with the automobile engine. The volume contains 55 papers divided into eighteen sessions.

The Leeds-Lyon symposia have well established themselves in the tribological calendar. Industrial progress requires a better understanding of interfacial phenomena than now exists and it is exciting to see that the topics addressed in these proceedings volumes are at the forefront of progress in tribological research. These proceedings contain 61 papers written by authors from all over the world, covering the entire spectrum of wear particles. Of particular interest is the detailed consideration of a wide range of particle formations and detachments, as well as a close look at the physics and chemistry of the wear of mechanisms, together with other in-depth state-of-the-art analytical contributions.

The tribological properties of relatively moving surfaces are greatly influenced by thin surface films which are of considerable importance in the design of machine components. From Victorian days when working lubricant films were calculated in tens of micrometres, to today when molecular dynamics simulations and even experiments are beginning to look at nanometre, single molecule thick films, the study of surfaces which is the tribologists'' challenge has moved to finer and finer scales.The 66 papers in this volume provide reviews across the tribological field with thin films as their theme, giving a comprehensive and concise description on topics ranging from coatings and surface modification to bio-tribology. The articles provide the reader with an outline of their most effective application and potential uses in new technologies. The volume will be of interest not only to research workers and design engineers in the fields of new machine developments and lubrication, but also to engineers and students specialising in tribology.

This book discusses dissipative phenomena, in particular the origins of friction at all scales, in mechanics, physics and chemistry, encountered in all fields of tribology, from thick film lubrication to dry friction.

These proceedings review progress in the development of lubricants and in the understanding of the phenomena of lubrication.The contents include papers on the impact of automotive technology and environmental factors upon lubricant requirements, elasto-hydrodynamic lubrication, boundary lubrication, machine elements, bio-tribology, metal forming, rheology, lubricated wear and very thin film (nano metre) lubrication. Presented by leading scientists from 22 different countries, these proceedings provide an up-to-date review of developments in this field.

The central theme of this book, The Third Body Concept: Interpretation of Tribological Phenomena, was chosen to honour the work of Professor Maurice Godet. The aim of this and previous conferences in the series is to select a topic of current interest to tribologists in order to further advance knowledge in selected fields. Presented by leading scientists from 23 countries, these proceedings provide an up-to-date review of developments in this field..

This volume represents the latest issue of a collection of Proceedings each dealing with a different topic in Tribology. This volume contains the Proceedings from the 23rd Leeds-Lyon Symposium which addressed the topic of Elastohydrodynamics and was attended by many international experts in the field.The Keynote Address was presented by Professor Stathis Ioannides on the subject of "Tribology in Rolling Element Bearings" and was followed by fifteen other sessions covering a wide variety of general areas from "Experimental" to "Lubricant Properties". In addition, nine other invited technical papers were presented to support the sessions.

The objective of the 28th Leeds-Lyon Symposium on Tribology was to define current understanding of the science relating to boundary and mixed lubrication and to compare this with the needs of industry in terms of applications.

Major advances have been made in recent years in areas such as contact mechanics, wear, elastohydrodynamic lubrication incorporating surface texture, lubricant interactions with surfaces and the experimental interrogation of surface topography, surface films and lubricant film thickness. However, the needs of industry are equally intense with a seemingly relentless drive towards more compact, efficient and durable tribological systems.

Boundary and Mixed Lubrication: Science and Applications publishes peer-reviewed papers presented at the 28th Leeds-Lyon Symposium on Tribology. The Keynote address was presented by Professor Koji Kato, Tohoku University, Sendai, Japan under the title "Wear of Boundary or Mixed Lubrication Regimes", which set the scene for the meeting with a review of recent scientific developments with a clear focus on the potential for technological and industrial development.

Tribology of Reciprocating Engines documents the proceedings of the 9th Leeds-Lyon Symposium on Tribology held at the University of Leeds, England on September 7-10, 1982. This book emphasizes advances in the working principals of the tribological components that operate with relative motion. The topics discussed include the dynamic analysis of engine bearing systems, measurement of oil film thickness in diesel motor main bearings, and temperature variations in crankshaft bearings. The theoretical and experimental study of ring-liner friction, tribology in the cylinders of reciprocating compressors, and lubricant properties in the diesel engine piston ring zone are also described. This text likewise considers the metallurgy of scoring and scuffing failure, impact of oil contamination on wear and energy losses, and role of tappet surface morphology and metallurgy in cam/tappet life. This compilation is a good reference for triblogists, lubrication engineers, and specialists researching on reciprocating engines.

The Running-In Process in Tribology is a collection of papers presented during the 8th Leeds-Lyon Symposium on Tribology held in the Institut National des Sciences Appliquées de Lyon, France in September 1981. The symposium was attended by 87 delegates from 13 countries, which showed a great level of interest on the scientific and industrial problems of running-in. Twenty eight papers are presented in the book, covering basic thermodynamics, mechanics of continuous solids, metallurgy, polymers, profilometry, and surface physics. Major topics such as elastohydrodynamics, roughness, and thermal effects in tribology are discussed as well. Mechanical engineers and materials scientists will find the book very insightful.

Developments in Numerical and Experimental Methods Applied to Tribology contains the proceedings of the 10th Leeds-Lyon Symposium on Tribology held at the Institut National des Sciences Appliquées in Lyon, France, on September 6-9, 1983. The papers explore developments in numerical and experimental methods used in tribology and cover topics ranging from ferrography and rheology to bearings and bearing dynamics, hydrodynamics, contact phenomena, and plasticity. The papers are organized into 13 sessions. The first two papers examine the use of ferrography in the analysis of non-ferrous particles as well as some of the methods of obtaining approximate numerical solutions to boundary-value problems that arise in elastohydrodynamic lubrication. The next session is concerned with rheology and contains papers that describe numerical solutions for power law fluids as applied to slider bearings; grease lubricated finite length bearings; and the use of the ball bearing as rheological test device. The papers that follow discuss bearings and their dynamics, oil films on lubricated surfaces, hydrodynamic lubrication, and finite element analysis of transient elastohydrodynamic lubrication. The final session considers plastic deformation, two body abrasion processes, and micropitting and asperity deformation. This monograph will appeal to tribologists.
