摘要：

The high-temperature oxidation behavior of Cr2AlC MAX phase and CoNiCrAlY used as bond coat layers in a thermal barrier coating (TBC) system with yttria-stabilized zirconia (YSZ) as the top coat is comparatively investigated in this study. The microstructural analysis revealed that the TBC system incorporating a Cr2AlC MAX phase bond coat exhibits exceptional resistance to oxidation, demonstrating no spallation even after exposure for up to 300 h under harsh conditions. This remarkable performance is attributed to the formation of a dense and protective alumina layer, which effectively mitigates oxidation and preserves the integrity of the coating system. The findings of this comparative study shed light on the superior oxidation resistance offered by Cr2AlC MAX phase as a bond coat material in TBC applications, offering valuable insights for the advancement of high- temperature protective coatings.
