Tribology : friction and wear of engineering materials

Covering both the mechanical and materials aspects of tribology, this accessible text provides the scientific and practical foundations necessary for a thorough understanding of the phenomena of friction, wear and lubrication. With an emphasis on the behaviour of materials, the book compares the tribological behaviour of metals, ceramics and polymers, equipping the reader to make reasoned judgements when confronted by practical problems.

Tribology covers the fundamentals of tribology and the tribological response of all types of materials, including metals, ceramics, and polymers. The book provides a solid scientific foundation without relying on extensive mathematics, an approach that will allow readers to formulate appropriate solutions when faced with practical problems. Topics considered include fundamentals of surface topography and contact, friction, lubrication, and wear. The book also presents up-to-date discussions on the treatment of wear in the design process, tribological applications of surface engineering, and materials for sliding and rolling bearings. Tribology will be valuable to engineers in the field of tribology, mechanical engineers, physicists, chemists, materials scientists, and students. Features Provides an excellent general introduction to the friction, wear, and lubrication of materials Presents a balanced comparison of the tribological behavior of metals, ceramics, and polymers Includes discussions on tribological applications of surface engineering and materials for sliding and rolling bearings Emphasizes the scientific foundation of tribology Discusses the treatment of wear in the design process Uses SI units throughout and refers to U.S., U.K., and other European standards and material designations
