Oxidation behavior of vanadium carbide powder.

Journal of Advanced Science, 1998
In this study, the oxidation of vanadium carbide (VC) powder at high temperatures was investigated in order to determine the possibility of its high-temperature use and additional material for improvement of the oxidation resistance of carbon-carbon (C/C) composites. VC powder with an average particle size of about 10μm was used in this experiment. The
