Book Review Engineering Tribology by J.A.Williams Dr Williams has written a comprehensive book dealing with the engineering aspects of Tribology. The book is essentially in four main parts. The first looks briefly at lubricant and bearing material properties. The second outlines the lore associated with solid/solid contact, including the eharacterisation of solid surfaces, contact mechanics and the friction and wear of solid surfaces. Then the classical regimes of lubrication from hydrodynamics to boundary lubrication are described. The last few chapters examine a few specific practieal aspects of engineering tribology, such as seals, metal working and rolling element beatings. The book ends with a series of "problems" which, no doubt have entertained students of the Engineering Department of the University of Cambridge as strongly as they will entrance the reader. The field that this book encompasses is very broad and this is both a strength and a weakness. Its strength is that it means

that Engineering Tribology is a useful compendium for the graduate engineer since it contains an introduction to many of the tribologieal problems which he or she may encounter in professional life. Its weakness is that each topic can, necessarily, be tackled only cursorily and that the author cannot bring to all areas the same originality and flair. This means that whilst some parts of the book, notably the last few chapters, are thorough and state of the'art, others are slightly old fashioned and dull. This is probably an unjust criticism since I suspect that the field of Tribology has grown so large that the subject can no longer be comprehensively and lovingly covered by one person in a single book, as in the halcyon days of Cameron's Principles of Lubrication. Overall Dr Williams book is a most useful addition to the tribology literature and will serve as both a valuable introduction and subsequent reference to many engineering ~ibologists. H. Spikes
