Friction Science and Technology: From Concepts to Applications, Second Edition
Authored by Dr. Peter J. Blau, Oak Ridge National Laboratory, Tennessee, USA,
Co-published by STLE and CRC Press (Taylor and Francis Group), 2008, hard cover, 440 pages.
The first edition of Friction Science and Technology was published in late 1995. Since that time we’ve seen many developments in our understanding of friction. Examples include new ASTM standards for friction measurement, laser-dimpled surfaces for friction control, friction of nanocomposites and alloys for lightweight bearings and, most important, leading-edge research on friction at the molecular scale—perhaps the fastest growing aspect of our field.
The second edition begins with a thorough development of the history of thought on the subject of friction, which puts the book in context. This history provides grounding for the main goal of the book—addressing the mechanics, materials and applications-oriented aspects of friction and friction technology. As a result, this book does a fine job of comprehensively covering the subject.
Key topic areas include:
I think the discussion on the same materials exhibiting different frictional behavior under differing contact conditions is particularly beneficial. So often in the past engineers would look up a material’s inherent coefficient of friction in some handbook and apply that to a design—with the totally mystifying result that the friction is much different.
A later chapters deals with run-in processes, which I found interesting as the importance of this is particularly acute in the bearings used in laser targeting and high-resolution photo-imaging devices. Also, there is a useful chapter on lubrication by gases, liquids and solids.
Another interesting chapter, Solid Friction of Materials, covers leather, wood, stone, metals, a variety of alloys, metallic glasses, ceramics, polymers, carbon/diamond-like materials and ice structures, to name just a few.
A unique feature is the inclusion in various chapters of numerous interesting and unusual examples of the application of friction science, proving that tribologists and tribological problems are truly an indispensible and multidisciplinary. A few examples highlighting the breadth of these applications are:
This aspect of the book alone makes interesting reading for both highly technical people as well as those with more than the usual curiosity for how things work. For more information about ordering this book for your technical library, log on to www.stle.org.
