Evaluation of the Tribological behavior of Nano-Onions in Krytox 143AB

Nanoparticles have been widely developed over the past ten years and have found several applications. This work presents the use of carbon nano-onions, i.e., nanoparticles, as a potential additive in an oil for aerospace application. The lifetimes were tested in ambient air and ultrahigh vacuum. Tribochemical products were characterized by micro Raman and FT-IR spectroscopies. It was shown that these particles can provide adequate lubrication very similar to graphitic material only when run in air.
