Abstract The thermal barrier coatings (TBCs) is an important technology for aero-engine hot components. Moreover, the strength analysis and lifetime prediction of TBCs are hot issues of basic research. During the service of hot components, the failure of TBCs will accelerate the degradation of substrate and threaten the safety of flight. The proper life model of TBCs can release the probability of failure and improve the reliability of engines. The damage mechanism of TBCs and the development of lifetime prediction were introduced. Furthermore, the development trend of thermal barrier coating life analysis technology for aero-engines was discussed.
