However, it has been reported that non-dope hydrogenated DLC films are easily eroded away by the hyperthermal O-atom collision in low Earth orbit (LEO). Metal-doing is expected to protect DLC film from a direct collision of O-atom by forming non-volatile surface oxide layer. In this study, effect of collision energy of O-atom on the oxide film formation at the Si or Ti-doped DLC surfaces was investigated. Hyperthermal O-atom collision in LEO was simulated by the laser-detonation atomic beam source which has widely been used for ground-based O-atom testing. A high-speed mechanical chopper wheel system (9000 rpm) located in front of the specimen converted the energy distribution of the O-atom pulse into the spatial distribution over the specimen. Surface oxidation states were analyzed by either conventional x-ray photoelectron spectroscopy. It was observed that the SiO2 and TiO2 were formed at the position relatively high-energy collision was occurred. In contrast, sub-oxides were observed where low-energy collision was occurred even though the fluence of O-atom is much higher than high-energy positions., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1530019013, レポート番号: JAXA-SP-14-012},
