Paper Title:
Effect of Substrate Conditions on Residual Stresses of Plasma-Spraying YSZ / Sm2Zr2O7 Thermal Barrier Coatings
  Abstract

Effect of substrate conditions, including material type, thickness and radius of substrate, on residual stresses of plasma spraying YSZ / Sm2Zr2O7 TBCs was analyzed through finite element method in this paper. Results show that all residual stresses increse with incresing of thermal expansion coefficient of substrate.Substrate thickness has slight effect on radial residual stress, and it has no effect on axial residual stress and shear stress. Effect of substrate radius on radial stresses can be almost neglected when it is over 18mm. Effect of substrate radius on axial stresses can also be ignored.
