The thermal barrier coating system is one of key technologies to improve reliability and service life of turbine vane and blade. Compatibility between the superalloy substrate and bond coat
damage of the TBCs subjected to CMAS deposit and methods to improve its resistance to CMAS
process control of thickness distribution over the turbine vane and blade
reduction in diameters of the cooling holes
in-situ nondestructive test of TBCs quality and refurbishment of worn TBCs are described with respect to engineering application technologies and problems to be solved for the TBCs on turbine vane and blade.
