Fabrication of ZrB<sub>2</sub>-SiC and its Related Composites by SPS and Their Oxidation Behavior
ZrB2 is a leading candidate for TPS for re-entry vehicles due to its high melting point, thermal shock resistance, and low density. ZrB2 does not fully possess oxidation resistance necessary for surviving the re-entry condition. It improves oxidation resistance when composited with SiC and can withstand the intense oxidation environment caused by aerodynamic heating during re-entry. In order to develop TPS, high-density ZrB2-SiC with different composition ratios were fabricated by the spark plasma sintering (SPS). In this research, ZrB2-SiC and related materials of UHTC, TiB2-SiC and TiC-ZrC, were fabricated by SPS and oxidation behavior was evaluated.
