Oxidation Behavior of a SPS Sintered ZrB2-SiC-MoSi2 Ceramic at 1500 °C
Science and Technology on Advanced High Temperature Structural Materials Laboratory, Beijing Institute of Aeronautical Materials, Beijing 100095, China
ZrB2-SiC-MoSi2 ceramic (ZSM) was successfully prepared by SPS sintering process. The micro-structure and mechanical property were characterized, the oxidation behavior of ZSM was mainly studied at 1500 °C in air. Compared to ZrB2-SiC ceramic (ZS), the mechanical property of ZSM was improved significantly. MoB phase increasing the mechanical and chemical bonding force between different phases was formed in ZSM during SPS sintering. After 10 h oxidation at 1500 °C in air, oxide layer thickness of ZSM was thinner than ZS, oxidation resistance of ZSM was better than ZS.
