The thermal barrier coatings (TBCs) offer the potential to improve efficiencies of aero engines significantly.
TBCs, typically consisting of an yttria-stabilized zirconia top coat and a metallic bond coat deposited onto
a superalloy substrate, are mainly used to extend a lifetime of gas turbine engine parts.
TBCs fabricated by EB-PVD are favored for high-performance applications, because of reduced
thermal conductivity, increased temperature capability, life prediction modeling, process modeling,
bond coat oxidation, and hot corrosion resistance as well as improved erosion behavior.
