− | '''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]]. | + | '''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.
