摘要

Dense and predominantly single-phase Cr2AlC MAX phase coatings without columnar structure were fabricated using an easy combined arc/sputtering deposition method followed by annealing. Isothermal oxidation of coatings was conducted under flowing air for 40 h M 900 - 1100 degrees C. Although the results revealed that the oxide scale showed strong dependence upon oxidation temperature, the coated samples remained intact even after oxidation M 1100 degrees C. Such excellent resistance to oxidation resulted in the parabolic kinetics exhibiting two stages. This was attributed to the formation of a dense and continuous Al2O3 interface layer and a (Cr, Al)(2)O-3 outermost layer.
