Tribology In Materials And Applications

This fully updated Second Edition provides the reader with the solid understanding of tribology which is essential to engineers involved in the design of, and ensuring the reliability of, machine parts and systems. It moves from basic theory to practice, examining tribology from the integrated viewpoint of mechanical engineering, mechanics, and materials science. It offers detailed coverage of the mechanisms of material wear, friction, and all of the major lubrication techniques - liquids, solids, and gases - and examines a wide range of both traditional and state-of-the-art applications. For this edition, the author has included updates on friction, wear and lubrication, as well as completely revised material including the latest breakthroughs in tribology at the nano- and micro- level and a revised introduction to nanotechnology. Also included is a new chapter on the emerging field of green tribology and biomimetics.

Tribology covers the fundamentals of tribology and the tribological response of all types of materials, including metals, ceramics, and polymers. The book provides a solid scientific foundation without relying on extensive mathematics, an approach that will allow readers to formulate appropriate solutions when faced with practical problems. Topics considered include fundamentals of surface topography and contact, friction, lubrication, and wear. The book also presents up-to-date discussions on the treatment of wear in the design process, tribological applications of surface engineering, and materials for sliding and rolling bearings. Tribology will be valuable to engineers in the field of tribology, mechanical engineers, physicists, chemists, materials scientists, and students.

This handbook provides an extensive reference source on the materials used in tribological applications. Materials used in tribological applications are, for the most part, common materials used for general engineering applications. Many conventional engineering materials have been adapted to tribological uses and examples of these are given throughout the text. Literature that so far has been scattered and difficult to retrieve is now presented for the first time in this comprehensive treatise. The author has used his expertise in selecting materials for a wide variety of friction and wear applications to develop this data base on materials for tribology. In addition information has been selected from the literature on the behaviour of these materials in bearings, seals, gears, brakes, clutches, wire rope, valves, cams and wear surfaces and is included in the descriptive text. The materials have been grouped in families, relating to their composition. A short table is provided at the beginning of each chapter, listing the ranges of selected properties for the materials under discussion. In addition there are short summaries of the tribological applications this class of materials is used for. On the first page of each chapter one can find a guide for the selection of materials. Sufficient references to the literature are given to enable the reader to follow up in more detail the various topics discussed.

The engineering and science of interacting surfaces in relative motion is known as tribology. It studies and applies the principles of friction, wear and lubrication. Tribology is an interdisciplinary field which draws upon other disciplines such as physics, materials science, biology, engineering, chemistry and mathematics. The fundamental concepts of tribology include tribosystem, tribofilm and stribeck curve. Tribosystem is useful in providing a comprehensive assessment of the important outputs, inputs and losses to tribological systems. Tribofilms are layers which form upon surfaces that are tribologically stressed, and reduce friction and wear in the tribological systems. The stribeck curve is used to understand how the friction in fluid-lubricated contacts is a non-linear function of lubricant viscosity, contact load and entrainment velocity. The topics included in this book on tribology are of utmost significance and bound to provide incredible insights to readers. This book consists of contributions made by international experts. It will help the readers in keeping pace with the rapid changes in this field.

Tribology and Applications of Self-Lubricating Materials provides insight into the complex mechanisms behind the development of self-lubricating materials, which due to their ability to transfer embedded solid lubricants to the contact surface to decrease wear rate and friction in the absence of an external lubricant, make up an important part of engineering materials used today. This book emphasizes an understanding of the tribological nature of different composites such as metal, polymer, and ceramic matrix composites and discusses the compatibility of these composites with specific lubricants. The book also offers a view of advancements in the development of self-lubricating mechanisms and covers the latest technologies in the field.

Principles and Applications of Tribology provides a mechanical engineering perspective of the fundamental understanding and applications of tribology. This book is organized into two parts encompassing 16 chapters that cover the principles of friction and different types of lubrication. Chapter 1 deals with the immense scope of tribology and the range of applications in the existing technology, and Chapter 2 is devoted entirely to the evaluation and measurement of surface texture. Chapters 3 to 5 present the fundamental concepts underlying the friction of metals, elastomers, and other materials. The principles of hydrodynamic lubrication are briefly discussed in Chapter 6, and the mechanisms of boundary and elastohydrodynamic lubrication are examined in Chapters 7 and 8. Chapter 9 is a generalized treatise on wear and abrasion phenomena in metals and elastomers, whereas Chapter 10 deals with the internal friction in solids, liquids, and gases. Chapter 11 is an abbreviated yet thorough treatment of experimental methods used in tribological studies. The remaining five chapters in this book are devoted to specific applications, including manufacturing processes, automotive applications, transportation, locomotion, bearing design, and miscellaneous. This book is an ideal source for mechanical engineering students.

Studying the morphology, defects, and wear behavior of a variety of material surfaces, Mechanical Tribology examines popular and emerging surface characterization techniques for assessment of the physical, mechanical, and chemical properties of various modified surfaces, thin films, and coatings. Its chapters explore a wide range of tribolo

This book brings together recent developments in the areas of MEMS tribology, novel lubricants and coatings for nanotechnological applications, biomimetics in tribology and fundamentals of micro/nano-tribology. Tribology plays important roles in the functioning and durability of machines at small length scales because of the problems associated with strong surface adhesion, friction, wear etc. Recently, a number of studies have been conducted to understand tribological phenomena at nano/micro scales and many new tribological solutions for MEMS have been proposed.
