Abstract
The effect of cryomilled bond coat material (MCrAlY) on the improvement of service life of Thermal Barrier Coatings (TBCs) was investigated. Creep resistance of the bond coat was greatly increased by the dispersoids formed during cryomilling. The creep mechanisms were found to be based on dislocation detachment from dispersoids for the cryomilled sample and grain boundary sliding for the conventional one. The results suggest that creep behavior has a great influence on the thermo-mechanical properties of the TBC.
