Industrial Lubrication

What Are Lubricants?

17.04.2017 tribonet

Definition Lubricant is a substance which is used to control (more often to reduce) friction and wear of the surfaces in a contact of the bodies in relative motion [1]. Depending on its nature, lubricants […]

Worn Steel Disk

Archard Wear Equation

04.04.2017 tribonet

The importance of wear losses leads to considerable effort in establishing theories and predictive models of wear. Meng and Ludema  [1] have identified 182 equations for different types of wear. Among them were empirical relations, […]

Elastic Deformation

Elastic Deformation

16.02.2017 tribonet

Definition Elastic deformation is a change of the shape of the body as a reaction to applied stress. This deformation is only temporary and once the stress is released, the undeformed shape of the body […]

Tribometers

14.02.2017 tribonet

Tribometers are the devices used to analyze and characterize tribological systems. The most common direct measurement is the measurement of friction coefficient (and shear strength). During the post processing stage other quantities can be measured, […]

Friction Coefficient Tables in Air and Vacuum

09.02.2017 tribonet

Friction coefficient table of solid lubricants, metals, plastics and anti-friction materials Friction coefficient table for various material pairs in atmosphere and vacuum (see the definition of friction coefficient) is shown below. The data was collected […]

Friction Coefficient

Coefficient of Friction

06.02.2017 tribonet

Friction is a force resisting relative motion and may occur at the interface between the bodies, but may also occur within the bodies. The concept of friction coefficient was first formulated by Leonardo da Vinci […]
