Tribology Wiki

Tribology Wikipedia has the same goal as the well-known Wikipedia: share knowledge from around the globe and create an encyclopedia accessible to anyone. Of course, Tribology Wiki has an emphasis in Tribology! Everyone is invited to read, write, edit and share Wikis. Please contact us via email if you would like to contribute an article or if you have any suggestions! You can create an article by going to Create New tab in any of the existing articles (you must be logged-in)

Lubrication and fuel efficiency

It is essential to enhance the fuel efficiency of all machines to mitigate emissions and reduce energy consumption. Automobiles and machinery rely on lubricants for optimum operation and efficient energy transfer. In all mechanical systems, lubrication plays a major role […]

Hydrostatic bearings

Hydrostatic bearings are a particular type of bearings that work on the principle of separating sliding surfaces using pressurized fluid: air, oil or any other type of lubricant. This is in contrast with hydrodynamic bearings, […]

Friction Brakes

Introduction A brake refers to a device that primarily plays the role of slowing down or bringing to a halt an object in motion such as a vehicle, a bike, train, an airplane, or roller-coaster. […]


Friction Test

In tribology, measurement of friction consists of the evaluation of forces that occur and oppose a relative motion in a tribological contact. According to ASTM standard G 40, the friction force is “the resisting force […]

Tire Friction

The wheel is an ingenious invention that made a huge impact on our lives. The main achievement here is the reduction of friction of the rolling wheel against the road as compared to the case […]


Meso Scale Air Journal Bearings

Meso scale air journal bearings are widely use in miniaturized rotary systems such as hard disk drives, laser scanners, micro motors, miniature precision machines, dentist drills, meso scale gas turbines, etc. In these systems the […]

Stribeck curve

Stribeck Curve

Stribeck curve is a fundamental and one of the most widely known concepts in tribology and lubrication fields. The concept represents the friction behavior in lubricated contacts as a function of viscosity of the lubricant, […]



Boundary Lubrication Boundary lubrication is the lubrication regime where the interface behaviour is dominated by chemical reactions that happen at the surfaces, tribofilm formation occurs, and the load is carried by the asperities. In the boundary lubrication regime the […]
