Abstract:
Thermal Barrier Coatings (TBCs) are thin layer of ceramic coating applied on components exposed to higher temperature to enhance the life. Manufacturers design variety of ceramic powders by combining the ceramic constituents. Ceramic powders gets adhered to metal to protect the metal substrate from heat and corrosive gases. Adhesion of powders depends on the thermal and physical properties of coating powder and metal substrate and the coating method employed HVOF, Plasma coating. The stress generated on the coating for due to combined effects of coating and metal substrate is essential for verification on the suitability of the coatings. Analysis of stresses using FEM method helps to predict the nature of stress generated and to predict the coating thickness requirement and help in use of best combination of thickness and method of coating applied. Therefore, simulation techniques such as FEM prove to be worth time saving as they help in reducing time consuming material and experiments as well as give precise results. FEM analysis was done to predict the stresses developed and the effect of intermediate bond coat to minimize the stress developed. These studies will be useful to predict the stresses location on the component and defect formation in TBCs during operation in turbine components
