Book Description
Tribology is emerging from the realm of steam engines and crank-case lubricants and becoming key to vital new technologies such as nanotechnology and MEMS. Wear is an integral part of tribology, and an effective understanding and appreciation of wear is essential in order to achieve the reliable and efficient operation of almost any machine or device. Knowledge in the field has increased considerably over recent years, and continues to expand: this book is intended to stimulate its readers to contribute towards the progress of this fascinating subject that relates to most of the known disciplines in physical science. Wear – Materials, Mechanisms and Practice provides the reader with a unique insight into our current understanding of wear, based on the contributions of numerous internationally acclaimed specialists in the field. Offers a comprehensive review of current knowledge in the field of wear. Discusses latest topics in wear mechanism classification. Includes coverage of a wide variety of materials such as metals, polymers, polymer composites, diamonds, and diamond-like films and ceramics. Discusses the chemo-mechanical linkages that control tribology, providing a more complete treatment of the subject than just the conventional mechanical treatments. Illustrated throughout with carefully compiled diagrams that provide a unique insight into the controlling mechanisms of tribology. The state of the art research on wear and the mechanisms of wear featured will be of interest to post-graduate students and lecturers in engineering, materials science and chemistry. The practical applications discussed will appeal to practitioners across virtually all sectors of engineering and industry including electronic, mechanical and electrical, quality and reliability and design.

Book Description
Sur tous les carters de moteurs d'avions, les vibrations se traduisent au niveau des assemblabes mécaniques par une sollicitation de fretting. Les dégradations qui en résultent peuvent générer des dysfonctionnements plus ou moins importants. Deux résultats essentiels sont mis en avant au cours de cette recherche. Le premier concerne une corrélation entre les paramètres de fretting et la propagation de fissures. Cette corrélation a abouti à la mise en oeuvre d'une méthodologie originale pour la détection in-situ de la propagation des fissures courtes sous fretting-wear. Le deuxième résultat est le développement d'une stratégie d'analyse de l'usure extensible aux matériaux sujets à l'adhésion. Dans le but de synthétiser cette approche, une carte d'usure en fretting est proposée. Elle tient compte simultanément d'une description phénomènologique de la nature du contact et d'une analyse quantitative de l'usure. Ainsi, il est possible d'identifier le scénario d'usure et, par conséquent, de cerner les mécanismes mis en jeu. La compétition entre fissuration et usure a fait l'objet d'une étude détaillée montrant en particulier le domaine critique de sollicitation pour lequel il y a compétition intensive des cinétiques d'usure et de fissuration. Dans l'optique d'améliorer la tenue au fretting des carters en alliage d'aluminium, une analyse systématique de l'influence des couches d'anodisation est appliquée. Un effet bénéfique de ces couches en usure est confirmé mais surtout elles assurent une meilleure protection des substrats contre la fissuration.

Book Description
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.

Book Description
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.

Book Description
This book reviews the current understanding of the mechanical, chemical and biological processes that are responsible for the degradation of a variety of implant materials. All 18 chapters will be written by internationally renowned experts to address both fundamental and practical aspects of research into the field. Different failure mechanisms such as corrosion, fatigue, and wear will be reviewed, together with experimental techniques for monitoring them, either in vitro or in vivo. Procedures for implant retrieval and analysis will be presented. A variety of biomaterials (stainless steels, titanium and its alloys, nitinol, magnesium alloys, polyethylene, biodegradable polymers, silicone gel, hydrogels, calcium phosphates) and medical devices (orthopedic and dental implants, stents, heart valves, breast implants) will be analyzed in detail. The book will serve as a broad reference source for graduate students and researchers studying biomedicine, corrosion, surface science, and electrochemistry.

Book Description
Materials and mechanical engineering researchers studying wear, fretting, elastic indentation testing and other tribological processes frequently need closed-form solutions for various attributes of contacts. These characteristics include contact law, pressure distribution, internal state of stress induced and the influence of friction. Materials and mechanical engineering researchers studying wear, fretting, elastic indentation testing and other tribological processes frequently need closed-form solutions for various attributes of contacts. These characteristics include contact law, pressure distribution, internal state of stress induced and the influence of friction. These solutions, scattered throughout the applied mechanics literature, are difficult to locate, are presented using a range of solution techniques, and express results in a way that is suitable only for experts in the field. `Mechanics of Elastic Contacts' uses a consistent set of recipes for the solution of all relevant problems, presents results in the simplest possible forms, and contains summaries using tabulated data. This reference source will provide a clear guide to elastic contacts for engineering designers, materials scientists and tribologists irrespective of their level of expertise in this important subject.
