Dry lubricant

Solid lubricants reduce friction due to the shape of the particles ( platelets) that easily slide over one another. The best known are graphite and molybdenum disulfide.

These lubricants are often used as an additive for lubricants and thermally highly loaded lubrication points.

Be used in addition to graphite and molybdenum disulfide also finely distributed soft metals (eg aluminum, copper, lead), ceramic particles, or plastics such as PTFE ( Teflon) in hot screw compounds.

As a release agent to improve the emergency running properties. Hot screw compounds reduce the risk of Verblockens eg by corrosion or cold welding of the bare metal surfaces of exhaust or spark plug threads or keep glands of brakes continuously, without flowing on the surface during hot Will. Graphite, MoS2 and ceramics are also offered as additives for motor oil, but be part of engine manufacturers for these lubricants (not included in the engine oil if any) no manufacturer approvals granted.

Also for the lubrication of rolling bearings solid lubricants are used when the particular conditions of use make ( for example, vacuum, high temperature, centrifugal forces, ionizing radiation in nuclear and space technology ) oil lubrication impossible.

Furthermore, partially used with MoS2 coated bullets to reduce at sporting arms the barrel wear and increase the muzzle velocity in favor of higher precision.
