Abstract

The microstructural analysis of Plasma Spray-Thermal Barrier Coatings (PS-TBC’s) is used to determine their properties and estimate lifetime of high temperature components used in turbines and other devices. The porosity is a microstructural characteristic of TBC’s that evolves with thermal exposure. In this work, the sintering and pore morphology in the TC (Top Coat) were studied as a function of the time of exposure at 1100°C for both continuous and cyclic conditions.The results of isothermal and thermal cycling tests were processed by digital image analysis.
