Tribology (griech.: Friction teachings) are a subsection of mechanical engineering and interdisciplinary from machine-builders, materials science-learn and physicists operated. It is concerned with the scientific description of friction, wear and lubrication as well as the development from technologies to the optimization of friction procedures.

The tribology e.g. examines friction, lubrication and wear of camps, guidance, transmissions, engines and other mechanical components.

Term

The term was used starting from approximately 1966 in England as technical term:

• After Peter Jost 1966: Tribology is the science and the technology of the surfaces influencing one on the other in relative motion and the practical procedures which are connected with it.

• According to DIN 50323 (standard withdrawn): Tribology is the science and technology of surfaces influencing one on the other in relative motion. It covers the total area of friction and wear, including lubrication, and includes appropriate boundary surface reciprocal effects both between solids and between solids and liquids or gases.

• After Czichos 1992: Tribology is an interdisciplinary field of activity for the optimization of mechanical technologies by reduction friction and wear-conditioned energy and material losses.

Important personalities

• Leonardo da Vinci,
• Guillaume Amontons (the two Amonton laws set up: The friction force is proportionally the normal force and independently of the apparent contact area, there Vinci was it already 100 years in former times well-known),
• Richard Stribeck (discovered the Stribeckkurve designated after it, which describes the coefficient of friction in lubricated camps) as well as
• Franc Philip Bowden and David Tabor, which wrote the first "modern" book to the tribology 1950.
