Abstract

When dispersed in a synthetic polyalphaolefin (PAO) base oil, inorganic fullerene-like (IF-MS 2) nanoparticles of metal dichalcogenides (IF-MoS 2, IF-WS 2, IF-NbS 2) lead to a significant reduction of both friction and wear under boundary lubrication. All IF nanoparticle additives resulted in a reduction of both friction coefficient and wear. There results were obtained even at low additive concentration. The best result was obtained with IF-WS 2 at 1 wt %. In this case, wear was very low because the calculated Hertz diameter was quite similar to the width of the pin wear scar diameter. This is an abstract presented at the World Tribology Congress III (Washington, DC 9/12-16/2005).
