摘要	Corrosion behavior of Cr2AlC in a high-temperature marine environment (with solid NaCl deposits in a 70 vol% H2O + 30 vol% O2) at 1000 degrees C was systematically investigated for the first time. This behavior was elucidated through analysis of complex corrosion products, microstructure of the oxide scale, and phase composition of the degraded region, supplemented by thermodynamic calculations. Synergistic effects of molten NaCl and water vapor, along with voids within the oxide scales and Na-induced amorphous Al2O3, promoted the loss of Al from substrate. Despite these factors, Cr2AlC was capable of spontaneously forming a protective oxide scale, which mitigates degradation. After 100 h of corrosion in a simulated marine environment at 1000 degrees C, Cr2AlC remained stable, exhibiting excellent corrosion resistance. Consequently, it holds significant promise for applications in high-temperature marine corrosion protection.
