Abstract

A smart bond coating was successfully identified for thermal barrier coatings (TBCs) that promotes appropriate protective scales preferentially during service depending on the environmental conditions. It enhances the life of super alloy components life significantly, which is essential for increasing the efficiency of advanced gas turbine engines. It is expected to be a potential bond coating for advanced gas turbine engine blades of different types, i.e., aero, industrial, and marine for their protection against high temperature oxidation, type I, and type II hot corrosion.
