Abstract

The effect of inorganic fullerene-like materials (IFLM) in lubricants on the contact fatigue and wear performance of tribological contacts subjected to rolling/sliding motion was studied. The lubricants tested were two gear oils 85W140 and FRL46 without IFLM and mixed with 5 and 3%IF-WS2, respectively. A very good performance was achieved with the lubricant 85W140 containing IFLM attributed to the tribofilm observed on the running surface. The influence of this tribofilm continued even after changing the lubricant to one without nanoparticles. The results showed a great potential for using inorganic fullerene-like nanoparticles as additives in oils in application where gears are prone to micropitting damage, such as wind turbines.
