Nanoparticles as Additives for the Development of High Performance and Environmentally Friendly Engine Lubricants

There has been growing interest in nanoparticles for tribological applications over the past 20 years. Studies have shown their remarkable lubricating properties, namely friction-reduction and anti-wear, especially when used as lubricant additives. This makes them potential candidates for replacing...

description	There has been growing interest in nanoparticles for tribological applications over the past 20 years. Studies have shown their remarkable lubricating properties, namely friction-reduction and anti-wear, especially when used as lubricant additives. This makes them potential candidates for replacing the additives currently used in automobile lubricants, known to be pollutants and less efficient in certain specific conditions. Among the nanoparticles with proven tribological performance are carbon nanoparticles (nanotubes, onion, diamond, etc.), BN and TiO2 nanoparticles, and Inorganic Fullerene-like (IF) metal disulfides (IF-MoS2, IF-WS2).
