Abstract

Upon cooling, plasma-sprayed ceramic barrier coatings generate large residual stresses, produced by the thermal expansion mismatch, the temperature profile, and the anisotropy of the phases. In this paper, a scheme for the purely elastic analysis of this stress formation is given, accounting for the different microstructure of successive coating layers. The presently considered microstructural data include the morphology and orientation pattern of the porosities. The coatings structure and temperature profile are computer-simulated.
