• OS1103 Development of CMAS Damage of Thermal Barrier Coating System

抄録

The use of thermal barrier coatings (TBCs) for turbine blades located in gas turbine engines has allowed higher engine operating temperatures exceeding the order of 1200℃ at the surface of the TBC top coat. At these high temperatures, the TBCs can be damaged by calcium-magnesium-alumino-silicates (CMAS) from the ingestion of mineral debris (dust, sand, ash) by the engine. In the present study, the CMAS damage was simulated in laboratory employing a synthetic CMAS product on Air Plasma splayed (APS) and Electron Beam Physical Vapour Deposition (EB-PVD) thermal barrier coatings. Microstructural observation showed the ingression of the CMAS into the TBC top coat and the dissolution of the TBC top coat into the CMAS. The effect of the CMAS product on the delamination behavior of the TBC top coat was also assessed.
