摘要	Alfa (alpha)-Al2O3 is widely used to resist oxidation at high temperature. However, presence of some transient phases can reduce the oxidation resistance. Several strategies have been proposed to solve this issue. Here, we found that nucleation of alpha-Al2O3 can be accelerated by a NiO layer on the surface of nanostructured Ni-7 wt%Al alloy. The oxidation rate constant is an order of magnitude lower than that of beta-NiAl after 1000 degrees C oxidation. The enhanced growth compressive stress in scale is supposed to facilitate the alpha nucleation. This provides a novel strategy to develop advanced engineering alloys with high temperature applications.
