What is tribology?

Tribology is the science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear. Tribology is a branch of mechanical engineering. The word tribology derives from the Greek root τριβ- of the verb τρίβω, tribo, “I rub” in classic Greek; and the suffix -logy from -λογία, -logia “study of”, “knowledge of”.

It was coined by the British physicist David Tabor, and also by Peter Jost in 1964, a lubrication expert who noticed the problems with increasing friction on machines, and started the new discipline of tribology.
