Effect of Heat Treatment on Pore Architecture and Associated Property Charges in Plasma Sprayed TBCs

, 2007
Plasma sprayed TBCs exhibit many interlamellar pores, voids and microcracks. These microstructural features are primarily responsible for the low global stiffnesses and the low thermal conductivities commonly exhibited by such coatings.
