Description:
In this work, the thermal shock behavior of laminated ZrB 2 –SiC ceramic has been evaluated using indentation-quench method based on propagation of Vickers cracks and compared with the monolithic ZrB 2 –SiC ceramic. The results showed that the laminated ZrB 2 –SiC ceramic exhibited better resistance to crack propagation and thermal shock under water quenching condition, and the critical temperature difference (Δ T c ) of laminated ZrB 2 –SiC ceramic (Δ T c ≈ 590°C) was much higher than that of monolithic ceramic (Δ T c ≈ 290°C). The significant improvement in thermal shock resistance was attributed to residual stresses enhancing the resistance to crack growth during thermal shock loading.
