摘要

ZrB2-SiC复合陶瓷的高热阻使其成为制造温度超过2000 °C的热防护结构的有希望的候选者。ZrB2-SiC复合陶瓷的一个显著优点是在循环温度作用下缺陷能自愈。本文研究了ZrB2-SiC复合陶瓷在1200、1400和1600 ℃退火下表面人工缺陷的自愈。结果表明，在1600° °C退火后，自愈过程最有效。发现复合陶瓷中SiC含量的增加和温度的升高使缺陷自愈能力增强。

Effect of ZrB2-SiC ceramics composition on defect self-healing

High thermal resistance of ZrB₂–SiC composite ceramics makes it a promising candidate for creating heat-protective structures operating at temperatures exceeding 2000 °C. A significant advantage of ZrB₂–SiC composite ceramics is self-healing of defects under cyclic temperature effects. The paper investigates self-healing of artificial defects on the surface of ZrB₂–SiC composite ceramics at 1200, 1400 and 1600 °C annealing. It is shown that the most efficient self-healing process occurs after 1600 °C annealing. It is found that defect self-healing increases due to the higher temperature and increased SiC content in composite ceramics.
