Abstract:

Thermal-mechanical coupling effect causes a large stress within porous ceramics at high temperatures, resulting in strength attenuation and product reliability decline. Thermal shock resistance is one of the key factors to characterize the reliability of ceramic materials under thermal-mechanical coupling effect. It is important to study the thermal shock resistance of the porous ceramics to evaluate their service performance and improve their service life. To better evaluate the effect of the thermal shock resistance on properties of the porous ceramics, the evaluation theories, experimental characterization methods and influencing factors about the thermal shock performance of the porous ceramics were reviewed in this paper, and some future research directions were prospected.

Key words: porous ceramics, thermal-mechanical coupling, thermal shock resistance, evaluation theory, influence factor
