Metallic Films with Fullerene-Like WS2 (MoS2) Nanoparticles: Self-Lubricating Coatings with Potential Applications

Abstract

Metallic fi lms impregnated with fullerene-like-WS 2 (MoS 2 ) nanoparticles were fabricated on stainless steel and Ti-Ni substrates using galvanic and electroless deposition. The coatings were obtained from aqueous suspensions containing the metallic salts as well as the dispersed nanoparticles. Tribological tests showed that the fi lms have low friction and wear. Such coatings could be useful for numerous civilian and defense-related applications.
