摘要：

A new Al-enriched gamma'-Ni3Al bond coat was developed and its oxidation behaviour was examined and compared to that of conventional Pt-diffused gamma/gamma' coatings and beta-NiPtAl coatings. This gamma'-Ni3Al coating exhibited significantly reduced elemental interdiffusion with the substrate during oxidation compared to two conventional coatings. Although Al-enriched gamma'-Ni3Al coatings presented faster thermal grown oxide (TGO) growth than the beta-NiPtAl coating, it outperformed beta-NiPtAl coatings regarding the rumpling resistance during cycling. The Al-enriched gamma'-Ni3Al coating also exhibited superior TGO spallation resistance compared to Pt-diffused gamma/gamma' coatings. The mechanisms for the reduced interdiffusion and good rumpling resistance of this gamma'-Ni3Al coating are addressed.
