| Summary | 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. |
