Outline of Final Research Achievements

Objectives in this study are to develop the ultrathin diamond like carbon(DLC) hybrid lubricant film with PFPE film deposited by the photoelectron assisted chemical vapor deposition method using the phenomenon that organic monomer gas molecules capture photoelectrons emitted from the DLC surface applied a bias voltage. Specifically, in order to increase the recording density of hard disk drives, we developed (1) hybrid lubricant film by atmospheric photoelectron assisted UV irradiation, (2) the photoelectron assisted organic thin film CVD method, (3) ultrathin DLC hybrid lubricant film. Then, (4) Tribochemical reaction of DLC film and lubricant · additive related with triboelectrons was studied.
