A fully updated version of the popular Introduction to Tribology, this book introduces MEMS, nanotribology and magnetic surface storage technologies as well as the breakthroughs in tribology at the nano- and micro- level. This fully updated edition of the leading tribology text explores the latest in our understanding of friction, wear, and lubrication. Considerations of friction and wear incorporate recent analysis and data work, and friction mechanisms are reappraised in light of current developments. Forward Preface 1.
