Degradation in a Thermal Barrier Coating [PDF]
Advanced Ceramic Materials, 1987 The failure of a thermal barrier coating involves cracking and spalling of the ceramic layer, primarily brought about by bond-coat oxidation during operation. The present investigation focuses on the microstructural and microchemical changes in a thermal barrier coating, oxidized in air for 1 and 10 h at 900{degree}C.

Bond Coat Development for Thermal Barrier Coatings [PDF]
Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; General, 1989 The use of thermal barrier coatings on high pressure turbine components can improve gas turbine efficiency through reduction of cooling airflow. However, to reduce cooling airflow, a highly reliable thermal barrier coating is required. This increased reliability will be achievable through several complimentary approaches: material and process ...
