Lubrication

Lubrication is the process or technique of using a <a href="/facts/Lubricant/9PXISDwU">lubricant</a> to reduce <a href="/facts/Friction/d0108Rpu">friction</a> and <a href="/facts/Wear_and_tear/Jd5HGq7U">wear and tear</a> in a contact between two surfaces. The study of lubrication is a discipline in the field of <a href="/facts/Tribology/13JNgmhS">tribology</a>.
Lubrication mechanisms such as fluid-lubricated systems are designed so that the applied load is partially or completely carried by <a href="/facts/Hydrodynamic/y7uzSCfg">hydrodynamic</a> or <a href="/facts/Hydrostatics/GYu6ljQ0">hydrostatic</a> pressure, which reduces solid body interactions (and consequently friction and wear). Depending on the degree of surface separation, different lubrication regimes can be distinguished.
Adequate lubrication allows smooth, continuous operation of <a href="/facts/Machine_element/cV69bkb9">machine elements</a>, reduces the rate of wear, and prevents excessive stresses or seizures at bearings. By repelling water and other substances, it also reduces corrosion. When lubrication breaks down, components can rub destructively against each other, causing heat, local welding, destructive damage and failure.
