AbstractTo tailor Ti2AlC coatings for the applications in accident tolerant fuels, the oxidation of near-stoichiometric and Al-lean Ti2AlC was investigated in Ar-41% H2O atmosphere in 1000-1200 degrees C. The oxidation kinetics of phase-pure Ti2AlC in high-temperature water vapor varied from parabolic to linear rate law with Al content decreasing. Insufficient Al content could not sustain the growth of continuous alumina scales, resulting in formation of thick unprotective TiO2-based scales. The formation of thin and protective Al2O3 scale for Ti2AlC with stoichiometric composition effectively inhibited the inward diffusion of water vapor. For the application of protective coatings on Zr-based cladding, stoichiometric Ti2AlC is expected to protect cladding from fast oxidation and improve the accident tolerance in the current light water reactors.
