Effect of Plasma Pretreatment on Thermal Durability of Thermal Barrier Coatings in Cyclic Thermal Exposure

<table>Elastic modulus values of TBCs before and after cyclic thermal exposure tests for 381 cycles: (A-1) APS bond coat, (A-2) HVOF bond coat, (A-3) C-NS top coat, (A-4) NS top coat, (B-1) and (B-2) APS bond coat with the C-NS and NS top coats, respectively, (B-3) and (B-4) HVOF bond coat with and without plasma pretreatment, respectively, (B-5) C-NS top coat, and (B-6) NS top coat. A and B series indicate the elastic modulus before and after cyclic thermal exposure tests for 381 cycles, respectively.</table>
