Abstract
ZrB2–SiCw ultrahigh-temperature ceramics have been investigated by water quench testing over the temperature range 400–1200 °C. All specimens preserved integrity and retained most of their strength (more than 80%) after being shocked for one or five cycles. Obvious surface changes as a result of oxidation were observed when testing at temperatures higher than 800 °C. Surface oxidation plays an important role in the thermal shock behavior of SiC-whisker-reinforced diboride ultrahigh-temperature ceramics.
