Lubrication Explained. Lubrication is the process or technique of using a lubricant to reduce friction and/or 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 or gases.

Lubrication reduces friction between the moving surfaces or rolling pairs. Some of the various types include hydrodynamic, hydrostatic, boundary and extreme pressure lubrication. The lubricant also act as a coolant carrying heat away from the sliding surfaces so it is necessary for all the moving parts in machinery or engine operation.

Lubrication mechanisms Fluid-lubricated systems. As the load increases on the contacting surfaces, three distinct situations can be observed with respect to the mode of lubrication, which are called lubrication regimes: [citation needed] Fluid film lubrication is the lubrication regime in which, through viscous forces, the load is fully supported by the lubricant within the space or gap ...

Regimes of Lubrication A lubricant is a type of substance which can be brought into the contact of loaded rolling / sliding bodies to control friction and wear. Most lubricants are some type of fluid (e.g. mineral and synthetic oils, etc.); however, there are some solid lubricants (e.g. gold, silver, polymers, etc.).

Basics of Lubrication. Lubrication reduces friction between moving parts by substituting fluid friction for solid friction. Without lubrication, it is difficult to move a hundred-pound weight across a rough surface; with lubrication, and with proper attention to the design of bearing surfaces, it is possible to move a million-pound load with a motor that is small enough to be held in the hand.
