tribology (rus. трибология) — (from Greek tribos meaning "friction") the science about fundamental and technical aspects of interaction of surfaces as they slide, as well as related phenomena and practical applications.


Through a detailed study of surface friction mechanisms, surface destruction and other accompanying processes, such as changing the properties of surface layers and heat generation, tribology can calculate the friction force, durability and wear and tear of structures, create models of surface interaction, develop the site construction principles, solve the problems of boundary hydrodynamics and lubrication of surfaces.

The founders of tribology are Leonardo da Vinci (1452-1519), who was the first to formulate the two basic laws of friction, Guillaume Amontons (1663-1705), who established the independence of the friction force on the nominal contact area, and Charles August Coulomb (1736-1806), who studied rolling, sliding and spinning friction with surface adhesion) factored in.
