N2 - In view of the high photonic thermal conductivity of thermal barrier coatings, a Gd-doped YSZ-NiCr2O4 composite (GYSZ-NCO) was designed, and its sintering parameters, thermal stability and thermal conductivity were analyzed. The results show that tetragonal GYSZ can be obtained when the sintering temperature is 1600 ℃. The GYSZ-NCO series materials have high thermal stability at 1500 ℃, and no phase transition occurs after holding for 300 h. After adding NiCr2O4, the thermal conductivity of GYSZ does not rebound significantly at high temperature, showing excellent thermal conductivity against photons. GYSZ-5%NCO material has the lowest thermal conductivity, which is only 2.23 W/(m·K) at 1200 °C.
