What Is Solid Lubrication

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.

What are advantages of solid lubricants?

Some advantages of solid lubrication are: (1) More effective than fluid lubricants at high loads and speeds. (2) High resistance to deterioration in storage. (3) Highly stable in extreme temperature, pressure, radiation, and reactive environments.

How does solid lubricant reduce friction?

Layered solid lubricants (boric acid, molybdenum disulphide and graphite) reduce friction by the mode of easy shear between their layers. They can be applied through buffing, sputter coating or as composite films on the sliding surfaces.
