Lubrication - Wikipedia

Lubrication is the process or technique of using a lubricant to reduce friction and wear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology.. Lubricants can be solids (such as Molybdenum disulfide MoS 2), solid/liquid dispersions (such as grease), liquids (such as oil or water), liquid-liquid dispersions [citation needed] or gases.
