Abstract

ZrB ₂ -based ultra-high temperature ceramics, as thermal protection materials, should bear thermal shock load during its service.On the basis of the dynamic thermoelastic equation, thermal shock behavior of ZrB ₂ -based ultra-high temperature ceramic under the cooling and heating condition was simulated,respectively.The influences of inertia item and coupling term on thermal shock resistance were investigated.The effects of surface heat transfer coefficient on the maximum stress and critical time were discussed. Furthermore,the predicted method of surface heat transfer coefficient in ZrB ₂ -based ultra-high temperature ceramic was presented through employing thermal fracture theory as a failure criterion,which can provide the evidence for thermal protection application of ZrB ₂ -based ultra-high temperature ceramics.
