Abstract：Thermal barrier coatings (TBCs) is a ceramic material used for thermal insulation of hot end parts of aeroengine. The thermal properties of this material will directly affect its thermal insulation performance. A review of the experimental and theoretical research on heat conduction and thermal radiation characteristics inside TBCs in recent years is presented. The macro-to-micro heat conduction theory and thermal radiation theory are introduced, and the cross-scale heat conduction and radiation processes in TBCs are analyzed. In theoretical aspect, the heat transfer theories under different scales and related theoretical research of TBCs are summarized in the order of macroscale to microscale. In experimental aspect, the research on heat transfer characteristic of TBCs with different materials and structures are summarized according to the development of TBCs materials. This review analyzes the research status of heat conduction and thermal radiation inside TBCs, and the future development direction of the research on heat transfer characteristics of TBCs is prospected.
