Abstract 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.
