The 14th International Conference on Wear of Materials took place in Washington, DC, USA, 30 March - 3 April 2003. These proceedings contain over two-hundred peer reviewed papers containing the best research, technical developments and engineering case studies from around the world. Biomaterials and nano-tribology receive special attention in this collection reflecting the general trends in the field. Further highlights include a focus on the new generation of instrumentation to probe wear at increasingly small scales. Approximately ninety communications and case studies, a popular format for the academic community have also been included, enabling the inclusion of the most up-to-date research. Over 200 peer-reviewed papers including hot topics such as biomaterials and nano-tribology Keeping you up-to-date with the latest research from leading experts Includes communications and case studies

Written by a tribological expert with more than thirty years of experience in the field, Mechanical Wear Fundamentals and Testing, Second Edition compiles an extensive range of graphs, tables, micrographs, and drawings to illustrate wear, friction, and lubrication behavior in modern engineering applications. The author promotes a clear understandin

Treatise on Materials Science and Technology, Volume 13: Wear provides a state of the art review of wear to form a basis for all future work on the subject and to be a standard work for all in the field. The book discusses the theories of wear and their significance for engineering practice; the wear of polymers; and the wear of carbons and graphites. The text also describes scuffing with regard to its physical manifestations, its importance in practice, theoretical interpretations advanced to describe and explain its occurrence. Abrasive wear; fretting; erosion caused by impact of solid particles; rolling contact fatigue; wear resistance of metals; and wear of metal-cutting tools are also looked into. Research workers, academic personnel, and students, as well as to tribologists, designers, practicing engineers, material scientists, physicists, chemists, and petroleum technologists will find the book invaluable.

Impact Wear of Materials is entirely devoted to quantitative treatment of various forms of wear occurring in impact-loaded mechanical components. Impact wear is classified under two headings, namely `erosive' and `percussive' wear. In erosive wear, particle streams and liquid jets are discussed. The subject is developed with emphasis on material relations, stress analysis and the historical progress of research. In percussive wear, a wide variety of wear mechanisms is described.The author's experimental/analytical work created the groundwork for a general procedure of impact wear-law formulation, combining impact analysis with the physical wear mechanism. Ballistic impact and pivotal hammering, compound impact, the optimal wearpath, lubrication, plasticity, and flexible media are some of the topics considered.The book develops a new conceptual approach to impact, impact-originated wear and wear in general. It describes and utilizes the modern tools of observation in wear science. In mechanical analysis it emphasizes quantitative treatment, using such tools as finite element stress analysis, APL programming language etc., each applied with classic simplicity. Numerous photographs, tables, figures and examples are used throughout the text and the mathematical treatment strives for simplicity and conceptual clarity. The book is of value to mechanical component designers, analysts and researchers. It is also useful in science and engineering curricula at senior and graduate level and, although its appeal is primarily in tribology, machine design and materials science, its interdisciplinary language makes it accessible to any branch of the physical sciences and engineering.

This book covers the area of tribology broadly, providing important introductory chapters to fundamentals, processing, and applications of tribology. The book is designed primarily for easy and cohesive understanding for students and practicing scientists pursuing the area of tribology with focus on materials. This book helps students and practicing scientists alike understand that a comprehensive knowledge about the friction and wear properties of advanced materials is essential to further design and development of new materials. The description of the wear micromechanisms of various materials will provide a strong background to the readers as how to design and develop new tribological materials. This book also places importance on the development of new ceramic composites in the context of tribological applications. Some of the key features of the book include: Fundamentals section highlights the salient issues of ceramic processing and mechanical properties of important oxide and non-oxide ceramic systems; State of the art research findings on important ceramic composites are included and an understanding on the behavior of silicon carbide (SiC) based ceramic composites in dry sliding wear conditions is presented as a case study; Erosion wear behavior of ceramics, in which case studies on high temperature erosion behavior of SiC based composites and zirconium diboride (ZrB2) based composites is also covered; Wear behavior of ceramic coatings is rarely discussed in any tribology related books therefore a case study explaining the abrasion wear behavior of WC-Co coating is provided. Finally an appendix chapter is included in which a collection of several types of questions including multiple choice, short answer and long answer are provided.

Metal alloys were tested for sliding friction and wear characteristics in vacuum and in air. One purpose was the analysis of variations in the coefficient of friction with changes in air pressure, hardness, and type of alloy. Another purpose was the evolution of a scheme for description of wear patterns. With a Bowden-Tabor apparatus, sliders of various alloys were revolved in contact with a steel plate. Soft and hard steel, titanium, aluminum, copper, and copper-beryllium alloys were tested. Hardness of steel in the plate was varied. Visual and metallographic inspection, as well as study of microhardness traverses from below the wear interface, provided the results. Photomicrographs showing wear in the metal alloys are presented. This paper also provides graphical description of variations in the coefficient of friction. A description of observed wear patterns is accomplished by a scheme of four categories: prow formation, severe rider wear, intermediate rider wear, and mild rider wear. In each category, wear pattern is correlated with a mechanism responsible for its formation.

A first introduction for beginner readers to the design and purpose of familiar items large and small. Children are encouraged to explore the world around them and think about why things are made the way they are.
