Friction, lubrication, adhesion, and wear are prevalent physical phenomena in everyday life and in many key technologies. This book incorporates a bottom-up approach to friction, lubrication, and wear into a versatile textbook on tribology. This is done by focusing on how these tribological phenomena occur on the small scale -- the atomic to the micrometer scale -- a field often called nanotribology. The book covers the microscopic origins of the common tribological concepts of roughness, elasticity, plasticity, friction coefficients, and wear coefficients. Some macroscale concepts (like elasticity) scale down well to the micro- and atomic-scale, while other macroscale concepts (like hydrodynamic lubrication) do not. In addition, this book also has chapters on topics not typically found in tribology texts: surface energy, surface forces, lubrication in confined spaces, and the atomistic origins of friction and wear. These chapters cover tribological concepts that become
increasingly important at the small scale: capillary condensation, disjoining pressure, contact electrification, molecular slippage at interfaces, atomic scale stick-slip, and atomic bond breaking.

Throughout the book, numerous examples are provided that show how a nanoscale understanding of tribological phenomena is essential to the proper engineering of important modern technologies such as MEMS, disk drives, and nanoimprinting. For the second edition, all the chapters have been revised and updated to incorporate the most recent advancements in nanoscale tribology. Another important enhancement to the second edition is the addition of problem sets at the end of each chapter.

Mathew Mate is currently a Visiting Scholar at the Chemical Engineering Department at Stanford University. Prior to that, he work for 30 years in industry for IBM, Hitachi, and Western Digital. He is best known for his research into the molecular and atomic levels and origins of tribology (the study of friction, lubrication, and wear). He has also been extensively involved in improving disk drive tribology. In recognition of his pioneering contributions to the field of tribology, he was awarded the 2001 MRS Medal from the Materials Research Society and the 2012 International Award from the Society of Tribology and Lubrication Engineers.

Robert Carpick, John Henry Towne Professor of Mechanical Engineering and Applied Mechanics at the University of Pennsylvania, studies nanotribology, nanomechanics, and scanning probes. He has received numerous awards include a NSF CAREER Award and the ASME Newkirk Award, and is a fellow of numerous societies, including the American Physical Society and the Society of Tribologists and Lubrication Engineers. He has authored 6 patents and over 170 peer-reviewed publications. Previously, he was a faculty member at the University of Wisconsin-Madison. He received his B.Sc. (University of Toronto) and his Ph.D. (University of California at Berkeley) both in Physics, and was a postdoc at Sandia National Laboratory.
