## Abstract During highβtemperature oxidation, the aluminide coating degrades by two mechanisms, one is the oxidation of the outer surface, and the other is Al diffusion into the substrate. The relevant laws are investigated for coatings on Coβbase superalloys oxidised in air at high temperatures.
## Abstract In the present study, the applicability of thermal barrier coatings (TBCs) on Ξ³βTiAl alloys was investigated. Two alloys with the chemical compositions of Tiβ45Alβ8Nbβ0.2Bβ0.15C and Tiβ45Alβ1Crβ6Nbβ0.4Wβ0.2Bβ0.5Cβ0.2Si were used. Before TBC deposition, the specimens were preβoxidised in
