摘要	A Ni3Al nanocrystalline film was deposited on the Ni3Al-based superalloy IC6 by magnetron sputtering. Pt-modified coatings were obtained by electroplating 1.5 mu m platinum onto the sputtered Ni3Al film with and without annealing. Duplex scale developed on the sputtered Ni3Al film after 20 h isothermal exposure at 1050 degrees C. Uphill diffusion of Al occurred in the Pt-modified coating system, which implied that inward diffusion of Al from coating to substrate was prevented. Platinum promoted selective oxidation of Al, although 5 at.% Pt was insufficient for the development of exclusive alumina scale on the Pt-modified sputtered gamma'-Ni3Al coating.
