Description
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.
