| Research Abstract |
The purpose of the study was to clarify the mechanism for the formation of boundary lubrication layer made by friction modifier additives and to understand the relationship between the later structure and tribological properties by means of neutron reflectometry and IR-RAS. The neutron reflectometry study showed that the additive layers made by long-chain fatty acids are monolayers, and IR-RAS study indicated that the additive layers grew up due to the friction process.
