Abstract

Nanoparticles such as inorganic fullerenes of metal dichalcogenides or carbon nanotubes have been recently used as lubricant additives and they present excellent tribological properties. Raman spectroscopy is a useful technique to follow modification of these two structures. We developed an original tribometer able to perform in situ Raman analyses during sliding steel on a sapphire flat. These analyses gave unique information on real-time structural changes of nanoparticles inside the contact area: inorganic fullerenes are tribologically active by a progressive exfoliation process and carbon nanotubes is changed to amorphous carbon. Lubrication mechanism of these particles are explained in the light of analytical results.
