Summary:To prevent the oxidation of ultra-high-temperature ceramic zirconium diboride (ZrB2) at high temperatures, this studyfabricated sintered composites containing silicon carbide and tungsten carbide, and examined the properties related to hightemperatureoxidation. Spark plasma sintering was employed for rapid sintering, and a high-temperature torch test wasconducted on samples to determine their surface oxidation behaviour. The composites oxidised at high temperature showeddifferent surface oxidation behaviour according to the type of carbide-based additive. Composites containing both carbides,which have different oxidation mechanisms, exhibited better resistance to oxidation than those containing a single carbide. KCI Citation Count: 0
