High Temperature Oxidation Behavior of ZrB2-SiC-Graphite Composite Heated by High Electric Current

摘要：

　　High temperature oxidation testing was carried out on hot-pressed ZrB2-SiC-graphite composite by using high electric current heating.The composites oxidation behavior was investigated,the temperature of oxidized specimens was above 2000℃.The results found that the UHTC composite was ruptured at oxidized temperature 2055℃.The microstructure of surface and cross-section of posttest samples were investigated by scanning electron microscopy along with energy and X-ray diffraction.The failure mechanism of rupture was also discussed.
