Tribology is the science and engineering of understanding friction, lubrication and wear phenomena for interacting surfaces in relative motion. It is highly interdisciplinary, drawing on many academic fields, including physics , chemistry , materials science , mathematics , biology and engineering . [ 1 ]
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. It includes the study and application of the principles of friction, lubrication and wear.
The complete description of a tribosystem is the first step when devising a tribological test procedure. Since tribological tests are often carried out on simplified model systems using standardized tribometers, a complete description of the tribosystem allows for tribological testing across different scales.
Nanotribology is the branch of tribology that studies friction, wear, adhesion and lubrication phenomena at the nanoscale, where atomic interactions and quantum effects are not negligible. The aim of this discipline is characterizing and modifying surfaces for both scientific and technological purposes.
The Stribeck curve is a fundamental concept in the field of tribology.It shows that friction in fluid-lubricated contacts is a non-linear function of the contact load, the lubricant viscosity and the lubricant entrainment speed.
Greenwood and Williamson in 1966 (GW) [31] proposed a theory of elastic contact mechanics of rough surfaces which is today the foundation of many theories in tribology (friction, adhesion, thermal and electrical conductance, wear, etc.). They considered the contact between a smooth rigid plane and a nominally flat deformable rough surface ...

They form as a result of complex mechanochemical interactions between surface materials and lubricants, [5] and the study of tribofilm formation processes is a major field of tribology. Generally, a tribofilm is any film that forms in a tribosystem "as a result of interaction between chemical components of the [lubricant] with the lubricated ...
