✦ Synopsis

Thermal barrier coatings (TBCs) for turbine airfoils in high performance engines represent an advanced materials technology that has both performance and durability benefits.Foremost of the benefits of TBCs is the reduction of heat transferred into aircooled components. Other potential benefits include increased resistance to hot corrosion, erosion and oxidation. To achieve these benefits, however, the TBC system must be rehable. Process-mlcrostructure relationships are considered to be key factors in the achievement ofTBC durabdity.Microstructural requirements for strain tolerance for both plasma-sprayed and electron beam physically vapor-deposited TBC systems are discussed. The effect of processing on bond coating oxidation and durability is also reviewed.

## Abstract Improved thermal barrier coatings can lead to increased engine operating efficiency. A significant problem is that multilayer systems are not thermally stable at elevated temperatures. Phenomena such as interdiffusion, oxidation and sintering take place, limiting coating lifetime. In or
