In this study, lubricant depletion due to high-frequency pulsed-laser heating, with a heating rate of ~108–109 K/s, was investigated for lubricant films with thicknesses of greater than and less than one monolayer. The conventional lubricants, Zdol2000 and Ztetraol2000, were used. It was found that the critical temperature at which the lubricants begin to deplete was strongly dependent on the lubricant film thickness. For lubricant film thicknesses of less than one monolayer, this temperature… CONTINUE READING
