Tribological Applications of WS₂ (MOS₂) Inorganic Fullerene-Like Nanoparticles as Solid Lubrication

Fullerene-like WS₂ (MoS₂) nanoparticles (IF) have been studied in the past [1–3] Their efficacy as additives for lubrication fluids has been demonstrated. [4–5] Recently, IF-WS₂ nanoparticles were confined inside a porous and densified bronze-graphite matrix, prepared by powder metallurgy (PM) technique. Substantial reduction in both friction and wear, and an increase in the critical load were observed [6]. New applications of IF nanopartcles as development of polymer nanocomposites, burnishing and friction of ceramic materials under severe contact conditions are presented in this work.
