In a fully updated edition, Principles and Applications to Tribology, Second Edition gives the solid understanding of tribology which is essential to engineers whilst designing 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 includes updates on friction and wear as well as completely revised material including the latest breakthroughs in tribology at the nano- and micro- level.
