摘要

The effects of ZrB₂ and ZrB₂+SiC additions on the oxidation kinetics of graphite at 1600-2000°C in air were investigated. The ZrB₂+SiC dual addition improves the oxidation resistance of graphite more effectively than the ZrB₂ single addition, because the oxide scale formed on C-ZrB₂-SiC is denser and thinner due to the existence of glassy SiO₂. As the oxidation temperature increases, the oxidation rate of C-ZrB₂-SiC gradually increases and oxide scales with layered microstructures form on its surface due to the greatly enhanced active oxidation of SiC at higher temperatures.
