Saliva is capable of decreasing friction force by at least 2 orders of magnitude when in between hydrophobic surfaces. This ability to lubricate is key to oral health, food processing and taste perception. In this paper different mechanisms of saliva lubrication are reviewed, and their interconnection is demonstrated using a simple physical framework ...

A reduction of friction between two sliding surfaces can be obtained by interposing a substance capable of reducing the shear stress, τm, necessary to allow the relative motion. This substance, which can be solid, liquid or gaseous, is called lubricant.

The fine-pored, easily compressed articular cartilage provides animal joints with self-pressurized hydrostatic (weeping) lubrication. The solid skeletons of the cartilages press against each other, but so lightly that their rubbing is lubricated successfully by synovial fluid--a boundary lubricant too weak to lubricate ordinary bearings.

In the gear units lubricants have a multiple function. First of all they are absolutely necessary to reduce the coefficient of friction between the elements that slide in relation to another. They also facilitates heat exchanges between equipment by carrying the heat produced by the friction whereas the dissipation of such forms of energy is easier and
