Abstract	The effects of surface temperature (1400-2000 degrees C), flow velocity gradient (130-600 s(-1)) and ambient pressure (5-101 kPa) on the oxidation behavior of graphite were studied in O-2. The weight loss rate between 1400 and 1800 degrees C is independent of the surface temperature but slightly decreases at 2000 degrees C. Besides, it displays quasi-parabolic increases with increasing the flow velocity gradient and the ambient pressure but levels off above the ambient pressure of 20 kPa. According to the theoretical analysis, the enhancement of the gas-phase CO-O-2 reaction has a joint reduction effect on the weight loss rate, (C) 2013 Elsevier Ltd. All rights reserved.
