Availability of crack-healing on the thermal shock resistance of ceramic components was investigated. Using gas quenching method, the crack-healed alumina-18 vol% SiC composite, which has excellent self-healing ability, was applied to thermal shock of the arbitrary quenching rate. The procedure could give rise to the thermal stress fracture at high temperature. It is clearly found that the thermal shock resistance was improved by using crack-healing.

研究了裂纹愈合对陶瓷构件抗热震性能的影响。采用气淬方法，将具有良好自愈能力的裂纹愈合铝-18 vol% SiC复合材料应用于任意淬火速率的热冲击中。这一过程在高温下会引起热应力断裂。结果表明，采用裂纹修复技术可以明显提高材料的抗热震性能。
