Description

Tribology is an unfamiliar term for many people, whereas it is encountered by all of us. It is the science of friction, lubrication and wear of moving solid components. The aim of Extreme Tribology is to provide a simple form of fundamentals along with the characteristics of tribological challenges in extreme working conditions. The first two chapters of the book offer a comprehensive review of the classical tribology of solid contacts, friction mechanics, wear mechanisms and lubrication techniques. These chapters are recommended for undergraduates and postgraduates studying tribology. In the following two chapters, the author discusses the main features of extraordinary conditions including, but not limited to, extreme environments, sliding severity and lubrication challenges.

The state-of-the-art researches on friction and wear under these extreme conditions are discussed extensively which will be of interest to researchers as well as postgraduate students. Chapters five and six discuss the development of solutions for extreme tribology, providing a complete overview to the various factors affecting tribo-systems in extreme conditions, and focusing on the recent progress in techniques used to control and reduce wear in such situations. In addition, tribology of automotive components is presented in chapter seven as tribological applications in practical situations. Chapter eight offers a basic understanding of the failure in tribological systems. The following two chapters explore current states and development trends in tribology of polymer composites and the emerging field of MEMS and NEMS with a special interest in the effects of environmental and working conditions. Diverse methods applied in predicting wear behavior by mathematical models, FE modeling and ANN approach are introduced in the last chapter. The book consists of eleven chapters and each of them is accompanied by relevant references.
