Oxidation Kinetics of ZrB₂ Ceramic Matrix Composite Materials

Abstract:

Zirconium diboride is widely applied because of some excellent performances. The oxidation kinetics of ZrB₂-YAG-Al₂O₃ composite materials were researched, which helps to improve the performance of ultra-high-temperature composite materials. The results show the oxidation weight gain is decreased with increasing the content of YAG-Al₂O₃ and the molar ratio of Al₂O₃. The oxidation weight gain is increased with prolonging the oxidation time under 1300°Cæ, the oxidation weight gain ratio is decreased with prolonging the oxidation time. The effecting tendency of oxidation weight gain is not abvious with varying the contend of YAG-Al₂O₃ upon 1300°Cæ, however, the effecting tendency of oxidation weight gain is very abvious with varying the molar ratio of Al₂O₃.
