Research Abstract

The thickness and density of the adsorbed additive layer on a metal surface under lubrication were directly measured by neutron reflectometry. Fitting operation based on Parratt's theory to the obtained reflectivity profiles showed that the thicknesses of the adsorbed layers on the iron and copper surfaces were quite thin, only 1-2 nm. In addition, a TOF-mode neutron reflectometer for structural analysis of solid-liquid interface was developed in the CN-3 in KURRI.
