Updated to include the timely and important topics of MEMS and rolling friction, Principles of Tribology is a compilation of current developments from tribology research, coupled with tribology fundamentals and applications. Essential topics include lubrication theory, lubrication design, friction mechanism, wear mechanism, friction control, and their applications. Besides classical tribology content, the book also covers intersecting research areas of tribology, as well as the regularities and characteristics of the tribological phenomena in practice. Furthermore, it presents the basic theory, numerical analysis methods and experimental measuring techniques of tribology as well as their application in engineering.   Newly expanded and updated to include new tribological material on MEMS and green tribology, its key concepts and applications Systematically brings the reader through fundamental theories, basic mechanisms through to the latest research Emphasizes practical tribological phenomena, supported by numerical analysis and experimental measurement techniques Discusses nano-tribology, thin film lubrication and its applications, topics which are growing in importance A comprehensive look at the fundamentals and latest research, this second edition of Principles of Tribology is an essential textbook for graduate and senior undergraduate students specializing in tribology and related mechanical engineering fields.
