A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.

Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology.
A lubricant is a substance used to reduce friction between moving surfaces. The property of reducing friction is known as lubricity (slipperiness). A good lubricant has the following characteristics: The most often used lubricant is motor oil, which is used in engines of cars and motorcycles.

The lubricityof many solids is attributable to a lamellar structure. The lamellae orient parallel to the surface in the direction of motion and slide easily over each other resulting in low friction and preventing contact between sliding components even under high loads. Large particles perform best on rough surfaces at low speed, finer particles o...
Solid lubricants are useful for conditions when conventional lubricants are inadequate, such as: 1. Reciprocating motion. A typical application is a sliding or reciprocating motion that requires lubrication to minimize wear, as, for example, in gear and chain lubrication. Liquid lubricants will squeeze out while solid lubricants do not escape, prev...
Spraying/dipping/brushing
Dispersion of solid lubricant as an additive in oil, water, or grease is most commonly used. For parts that are inaccessible for lubrication after assembly, a dry film lubricant can be sprayed. After the solvent evaporates, the coating cures at room temperature to form a solid lubricant. Pastes are grease-like lubricants containing a high percentage of solid lubricants used for assembly and lubrication of highly loaded, slow-moving parts. Black pastes generally contain MoS2. For high temperat...
Free powders
Dry-powder tumbling is an effective application method. The bonding can be improved by prior phosphating of the substrate. Use of free powders has its limitations, since adhesion of the solid particles to the substrate is usually insufficient to provide any service life in continuous applications. However, to improve running-in conditions or in metal-forming processes, a short duration of the improved slide conditions may suffice.[citation needed]
Anti-friction coatings
Anti-friction (AF) coatings are "lubricating paints" consisting of fine particles of lubricating pigments, such as molydisulfide, PTFE or graphite, blended with a binder. After application and proper curing, these "slippery" or dry lubricants bond to the metal surface and form a dark gray solid film. Many dry film lubricants contain special rust inhibitors which offer exceptional corrosion protection. Most long-wearing films are of the bonded type but are still restricted to applications wher...

A lubricant (colloquially, lube) is a substance (often a liquid) introduced between two moving surfaces to reduce friction and wear between them. A lubricant provides a protective film that allows for two touching surfaces to be separated, thus lessening the friction between them.
Lubrication is a physical process which allows surfaces to move smoothly against each other. A thin film of lubricant put between the surfaces reduces friction and wear on the surfaces, and keeps temperatures from rising too far.
