LofDIAMS: Low and ultralow friction of microcrystalline diamonds films – towards smart and tribo-resistant coatingsAxes: Surfaces & Interfaces, Materials & Structure DesignLeaders: Hiroyuki MIKI (FRIIS, TU) & Michel BELIN (LTDS, ECL)A project has started, concerning low and ultralow friction of carbon-based coatings. It is related to “Superlubricity”. The objective is to describe the low friction behavior of partially-polished microcrystalline diamond films. The goal is to depict and precisely quantify the different contributions to friction (velocity-dependent and Coulomb-type contributions), in different contact conditions. Experimental work is involving mainly i/ coating elaboration in TU, ii/ and the “relaxation tribometer“ technique in LTDS. Those films will be applied as the smart and tribo-resistant coatings, especially to the bearings under extreme environments.Articles in peer-reviewed international journals
