Abstract:BaO-MgO-SiO 2 based glass-ceramics was used as bond coat between 8 wt. % yttria stabilized zirconia (8YSZ) top coat and nickel based superalloy substrate of a thermal barrier coating (TBC) system. The glass-ceramic bonded TBC system was characterized in terms of microstructure and mechanical properties (e.g. nanohardness, Young's modulus). The nanohardness and Young's modulus values of 8YSZ top coat, glass-ceramic bond coat and substrate of the TBC system were lower on the crosssection than those obtained on i… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
