ABSTRACT:
A solid lubricating composition and method for forming such a composition are disclosed. The composition is formed by intercalating a transition metal that has been chemically reacted with chalcogen to form a layered structure. The transition metal is selected from niobium, tantalum, tungsten and/or an alloy including one or more, and the transition metal is chemically combined with chalcogen selected from sulfur, selenium and/or a combination which can also include tellurium to form a layered transition metal dischalcogenide prior to intercalation with a metal, preferably a coinage metal. The effect of intercalation is to expand the crystal lattice to create a composition having excellent lubricating characteristics the performance of which is not adversely effected by operation in a high temperature environment.
