Definition of solid lubricant: A solid
lubricant is a material used as powder or thin film to
provide protection from damage during relative movement and
to reduce friction and wear. Other terms commonly used for
solid lubrication include dry lubrication, dry-film
lubrication, and solid-film lubrication. Although these
terms imply that solid lubrication takes place under dry
conditions, fluids are frequently used as a medium or as a
lubricant with solid additives. Perhaps the most commonly
used solid lubricants are the inorganic compounds graphite
and molybdenum disulfide (MoS2 ) and the polymer
material polytetrafluoroethylene (PTFE).
