Abstract

Boron carbide is the basic constituent of multi-layered self-healing ceramic matrix composites. In this paper, BC_x was prepared by Chemical Vapor Deposition (CVD). Oxidation behavior of CVD-BC_x was investigated under wet oxygen atmospheres at the temperature ranged from 700 to 1200°C, combined with the thermodynamic calculation of B₂O ₃ volatilization with water vapor. The oxidation mechanism of CVD-BC_x and the effect of water vapor on the oxidation behavior of CVD-BC_x were analyzed. It is found that, at intermediate temperature (700°C), with the increment of water vapor content, oxidation of CVD-BC _x turns from passive mode to active mode. While at high temperature (1000-1200°C), the influence of water vapor on the oxidation behavior of CVD-BC_x becomes less, the temperature is the main factor influencing the oxidation of CVD-BC_x.
