Investigation of the Physicochemical Properties of Ceramics in the Sm2O3–Y2O3–HfO2 System for Developing Promising Thermal Barrier Coatings
The effect of components of ceramics in the Sm 2 O 3 –Y 2 O 3 –HfO 2 system on their thermophysical properties was studied. It was shown that the most stable materials at 1400°C are ternary ceramics in the system under investigation that contain ≤12.5 mol % Sm 2 O 3 ; the thermal conductivity of the...
