Nano structures at solid-liquid interfaces were analyzed by neutron reflectometry in this paper. We prepared two kinds of metal surfaces, iron and copper, on ultra-flat silicon blocks by physical deposition. We analyzed each target surface using neutron reflectometry in air, in base oil (poli-alpha-olefin) and in base oil with an additive (acetic acid). Fitting operation along Parratt's theory showed that the thickness of adsorbed layer was about 2 or 3 nm. Friction coefficients of the metal surfaces considerably decreased when the additive was added in the base oil. We conclude that nano structure of interface between metal surface and lubricant considerably affects friction property.
