Abstract | Hf and/or Y doped (Ni,Pt)Al coatings were prepared to investigate their initial oxidation behavior and cyclic oxidation performance at 1150 degrees C. Finer grain sizes were observed in Hf and/or Y doped (Ni,Pt)Al coatings in as-received state, wherein the best oxidation resistance was achieved in the co-doped coating. In oxidation, Hf and Y were observed synchronously segregating at grain boundaries of alumina scale, which more effectively retarded the phase transformations of theta-Al2O3 to alpha-Al2O3 for the oxide scale and from beta to gamma' for the coating. Mechanisms responsible for the merits of Hf-Y co-doping in (Ni,Pt)Al coating are discussed. |
