==Origin==
[[Latin]] ''lubricatus'', past participle of ''lubricare'', from ''lubricus'' slippery
*[http://en.wikipedia.org/wiki/17th_century 1623]
==Definition==
*1: to make smooth or slippery
==Description==
'''Lubrication''' is the [[process]], or [[technique]] employed to reduce wear of one or both [[surfaces]] in close proximity, and moving [[relative]] to each other, by interposing a substance called ''lubricant'' between the surfaces to carry or to help carry the load ([[pressure]] generated) between the [[opposing]] surfaces. The interposed lubricant film can be a solid, (e.g. [http://en.wikipedia.org/wiki/Graphite graphite], MoS2) a solid/liquid [[dispersion]], a liquid, a liquid-liquid dispersion (a [http://en.wikipedia.org/wiki/Grease_(lubricant) grease]) or, exceptionally, a [[gas]].
In the most common case the applied load is carried by [[pressure]] generated within the [[fluid]] due to the [[friction]]al viscous [[resistance]] to [[motion]] of the lubricating fluid between the surfaces.
Lubrication can also describe the [[phenomenon]] such reduction of wear occurs without human [[intervention]] (hydroplaning on a road).
In the [[science]] of [[friction]], lubrication and wear is called [http://en.wikipedia.org/wiki/Tribology tribology].
Adequate lubrication allows smooth continuous operation of equipment, with only mild wear, and without excessive [[stresses]] or seizures at bearings. When lubrication breaks down, metal or other [[components]] can rub destructively over each other, causing destructive damage, [[heat]], and [[failure]].[http://en.wikipedia.org/wiki/Lubrication]
