Fundamentals of tribology.


Fundamentals of tribology tribology

Study of the interactions of sliding surfaces. It includes three subjects: friction, wear, and lubrication. Many manifestations of tribology are beneficial and make modern life possible.

The study of lubrication lubrication, introduction of a substance between the contact surfaces of moving parts to reduce friction and to dissipate heat. A lubricant may be oil, grease, graphite, or any substance—gas, liquid, semisolid, or solid—that permits free action of  and wear leads to improvements in everything from a racing car's engine to face cream. Tribologists also contribute to the development of artificial body joints and tissues. This classroom text provides simple approximate solutions to practical problems, and considers the availability of sophisticated computer systems, even to the lowliest undergraduate.

Imperial College was founded in 1907, with the merger of the City and Guilds College, the Royal School of Mines and the Royal College of Science (all of which had been founded between 1845 and 1878) with these entities continuing to exist as "constituent colleges".

A gas, liquid, or solid used to prevent contact of parts in relative motion, and thereby reduce friction and wear. In many machines, cooling by the lubricant is equally important.
