SuperLub: Superlubricity: Experimental and Computer SimulationsAxes: Surface & Interfaces, TransportationLeaders: Momoji KUBO (TU) & Jean-Michel MARTIN (LTDS, ECL)Participants: Maria Isabel DE BARROS-BOUCHET (LTDS, ECL)Superlubricity is an area of tribology that is becoming increasingly important as evidenced by the large number of scientific articles and the creation of a specific session at the next WTC in Beijing. Our main interest is reaching superlubricity in presence of carbon coatings (diamond NCD, ta-C and a-C:H) lubricated by green lubricants (gas, water, fatty acids etc.). Our project will first focus on the effect of water and unsaturated fatty acids (oleic, linoleic and linolenic acids). New mechanisms of superlow friction by surface aromatization will be studied by dedicated techniques (including synchrotron radiation SOLEIL in Paris) and computer simulations at FRRI at Sendai.Articles in peer-reviewed international journals
