Tribology

The word tribology comes from the Greek root τριβ- verb τρίβω (tribo), literally "rub, rub." It was first used by the English physicist David Tabor ( born David Tabor ) and Peter Jost ( English Peter Jost ) in 1964, an expert in the field of lubrication, who drew attention to the problems associated with increased friction in machines, and introduced a new discipline - tribology.

Tribology studies friction processes directly, and tribological techniques study their application in machine nodes. In recent years, new sections have been developed in tribotechnology - tribochemistry, tribophysics and tribomechanics. For the first time the processes of friction were studied by Leonardo da Vinci.

Tribometry is a system of methods and tools for measuring friction forces , wear and carrying capacity of rubbing bodies. Measurements obtained directly in the process of friction interaction , allow simple calculations to determine the magnitude of the friction coefficient , wear rate, permissible loads, speeds and temperatures .

The main parameter characterizing friction is the friction coefficient:
