Summary
The result of Kenneth C Ludema's 35 years of teaching and research, Friction, Wear, Lubrication: A Textbook in Tribology presents a broad view of the many aspects of tribology. All major aspects of this discipline are included, from mechanical to materials to chemical to mechanics. Ludema's key research areas - marginally lubricated wear and friction - will be of special interest to readers who would like to find reliable and useful data on friction and wear rates.
Written primarily as a text/reference, this informative volume describes how to solve design problems in friction and wear. By applying close and informed observation of presently operating tribological systems, along with careful design of simulative tests, readers can develop their own conclusions of tribological results. This book is intended to bring everyone solving problems in friction and wear to the same understanding of what is (and what is not) involved in this exciting field.
Seniors and graduate students, as well as practicing engineers employed in a wide range of industries will find this book to be an essential and practical resource.

Editorial Reviews
"This book is the 'final' form of a set of course notes I have used since 1964. Hundreds of students and practicing engineers have helped me over the years to gain my present perspective on the complicated and fascinating field of tribology. I hope you will find this book useful."
