| Research Abstract |
We proposed a lubricant reserver system in which lubricants supplied from a small gap between a hub and a disk plate to disk surfaces. A flow of Perfluorinated Polyether (PFPE) lubricant was examined with cylindrical lens which enable to prepare nanometer scale gaps. As a result, the flow rate parabolically decreases with the decreased gap. Further, it was found that the PFPE lubricant molecule adsorbed on a substrate surface at a functional group, phosphazene, in the molecule with a Surface Enhanced Raman Scattering (SERS) technique.
