This seminar provides a very comprehensive and up-to-date overview of the rapidly expanding field of tribology. First friction, wear, and lubrication including a brief historical evolution of tribology over millennia will be introduced and described in detail. Progressively, the properties and main characteristics of tribological surfaces where friction, wear, and lubrication take place will be addressed, also various methods used for measuring surface roughness, mechanical, chemical, and physical properties all of which are critically important for the tribological performance of all moving mechanical systems will be described. A section on friction and wear introduces basic concepts, theories, mechanisms involved and in minimizing friction and wear. The friction and wear of specific material groups or classes are presented to further emphasize the fact each material type or coating can differ from one another in their friction and wear behaviors mainly because of the stark differences in their structural, chemical, mechanical, and physical properties. The seminar will then focus on the topic of tribology in extreme environmental conditions. Space tribology as one of the tribology challenges in such working conditions will be overviewed. Characteristics of tribological systems operating under extreme conditions involving extraordinary temperatures, speeds, and vacuum are discussed. ]]>

This book offers fundamentals and a comprehensive overview of tribology in sever conditions. It addresses a comprehensive coverage of classical tribology of solid contacts, friction mechanics, wear mechanisms and lubrication technologies. Characteristics of tribological systems operating under extreme conditions involving extraordinary loads, temperatures, speeds, and vacuum are discussed. Surface coating, surface treatment, and lubrication are argued considering the cutting-edge researches. In addition, tribology of automotive components is presented, as are tribological applications in many practical situations. The tribology of polymer composites, MEMS and NEMS are explored. A basic understanding of failure in tribological systems is covered. Various test methods used in evaluating wear are reviewed. Diverse techniques applied in predicting wear behavior by mathematical models, FE modeling and ANN approach are discussed.]]>
