Abstract
Three kinds of Pt-rich γ-γ’ bond-coating were processed with different contents in Pt and Al. The cyclic oxidation tests performed at 1100 °C on TBC systems showed the superiority of the Pt-rich γ-γ’ coatings when compared with the β-(Ni,Pt)Al reference system. TBCs with a Pt-only bond-coating provided the highest performance. Whatever the bond-coating, the failure occurred at the TGO/bond-coating interface which appeared to be the weak point of these γ-γ’ bond-coating based systems. Al addition during bond-coating fabrication did not improve the durability. A decrease of 2 μm of electroplated Pt thickness led to a higher performance than the reference systems.
