Abstract

Thermal barrier coating (TBC) system consisting of yttria stabilized zirconia (YSZ) top coat, glass-ceramic bond coat and nickel base superalloy substrate was subjected to static oxidation test at 1200 degrees C for 500 h in air. Oxidation resistance of this TBC system was compared with the conventional TBC system under identical heat treatment condition. Both the TBC systems were characterized by SEM as well as EDX analysis. No TGO layer was found between the bond coat and the top coat in the case of glass-ceramic bonded TBC system while the conventional TBC system exhibited a TGO layer of about 16 mu m thickness at the bond coat-top coat interface region.
