Principles And Applications Of Tribology

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.

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.

Professors Wen and Huang present current developments in tribology research along with tribology fundamentals and applications, including lubrication theory, lubrication design, friction mechanism, wear mechanism, friction control, and their applications. In addition to classical tribology, Wen and Huang cover the research areas of the modern tribology, as well as the regularities and characteristics of tribological phenomena in practice. Furthermore, the authors present the basic theory, numerical analysis methods, and experimental measuring techniques of tribology as well as their applications in engineering. Provides a systematic presentation of tribology fundamentals and their applications Discusses the current states and development trends in tribology research Applies the applications to modern day engineering Computer programs available for download from the book’s companion site Principles of Tribology is aimed at postgraduates and senior-level undergraduates studying tribology, and can be used for courses covering theory and applications. Tribology professionals and students specializing in allied areas of mechanical engineering and materials science will also find the book to be a helpful reference or introduction to the topic.

A fully updated version of the popular Introduction to Tribology, the second edition of this leading tribology text introduces the major developments in the understanding and interpretation of friction, wear and lubrication. Considerations of friction and wear have been fully revised to include recent analysis and data work, and friction mechanisms have been reappraised in light of current developments. In this edition, the breakthroughs in tribology at the nano- and micro- level as well as recent developments in nanotechnology and magnetic storage technologies are introduced. A new chapter on the emerging field of green tribology and biomimetics is included. Introduces the topic of tribology from a mechanical engineering, mechanics and materials science points of view Newly updated chapter covers both the underlying theory and the current applications of tribology to industry Updated write-up on nanotribology and nanotechnology and introduction of a new chapter on 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. Features Provides an excellent general introduction to the friction, wear, and lubrication of materials Presents a balanced comparison of the tribological behavior of metals, ceramics, and polymers Includes discussions on tribological applications of surface engineering and materials for sliding and rolling bearings Emphasizes the scientific foundation of tribology Discusses the treatment of wear in the design process Uses SI units throughout and refers to U.S., U.K., and other European standards and material designations

Tribology is related to friction, wear and lubrication of machine elements. Tribology not only deals with the design of fluid containment systems like seals and gasket but also with the lubrication of surfaces in relative motion. This book comprehensively discusses the theories and applications of hydrodynamic thrust bearing, gas (air) lubricated bearing and elasto-hydrodynamic lubrication. It elucidates the concepts related to friction, including coefficient of friction, friction instability and stick-slip motion. It clarifies the misconception that harder and cleaner surfaces produce better results in wear. Recent developments, including online condition monitoring (an integration of moisture sensor, wear debris and oil quality sensors) and multigrid technique, are discussed in detail. The book also offers design problems and their real-life applications for cams, followers, gears and bearings. MATLAB programs, frequently asked questions and multiple choice questions are interspersed throughout for easy understanding of the topics.

By focusing on the theory and techniques of tribological design and testing for bearings, this book systematically reviews the latest advances in applications for this field. It describes advanced tribological design, theory and methods, and provides practical technical references for investments in bearing design and manufacturing. The theories, methods and cases in this book are largely derived from the practical engineering experience gained and research conducted by the author and her team since the 2000s. The book includes academic papers, technical reports and patent literature, and offers a valuable guide for engineers involved in bearing design. The book is intended for engineers, researchers and graduate students in the field of mechanical engineering, especially in bearing engineering.
