Influence of Substrate Condictions on Thermal-Shocking Property of Sm₂Zr₂O₇/NiCoCrAlY Graded Thermal Barrier Coatings

Abstract:

The effect of substrate conditions, including material type, thickness and radius on thermal shocking properties of plasma sprayed Sm₂Zr₂O₇/NiCoCrAlY functional graded thermal barrier coatings were analyzed by ANSYS—a finite element method software. Results show that thermal stresse in coatings increase with increasing of thermal expansion coefficients of substrates. The effect of substrate thickness can be ignored when it is greater than 20mm. Thermal stresses increase with radius increasing, however, they are almost not effected when substrate radius is over 18mm.
