PREPARATION AND PROPERTIES OF ZIRCONIUM DIBORIDE-BASED ULTRA-HIGH TEMPERATURE CERAMICS
摘要
Abstract
Zirconium diboride (ZrB2)-based ultra-high temperature ceramics (UHTC) reinforced by silicon carbide (SiC) particles were prepared by hot press sintering at 1 950 ℃ for 1 h under 20 MPa pressure in an argon flow. The relative density of ZrB2/SiCpcomposites increased with the content of SiC addition, and reached 100% when 15% (in volume) SiC particles were added. The bending strength and toughness of the composites also increased with increasing SiC amount, and reached values of 646 MPa and 8.52 MPa-m1/2, respectively, at 15% SiC addition. Furthermore, the addition of SiC particles improved the resistance to oxidation/ablation of ZrB2/SiCp composites.关键词
