title = "Improvement in oxidation resistance of Ni3Al based single crystal superalloy IC32 by NiAlHfSi coating",
abstract = "In order to improve the oxidation performance of IC32, the NiAlHfSi coating was deposited on the alloy by electron beam physical vapor deposition (EB-PVD) method. The oxidation resistance of the coated alloy at 1423 K was investigated. The microstructures of the samples before and after oxidation were examined by SEM, XRD and EPMA. It was found that the oxide scales compactly formed on the surface of the coating, and the oxidation mainly consisted of Al2O3 and NiAl2O4. Phase transformation occurred from β-NiAl to γ′-Ni3Al in the coating after oxidation for extend periods. The diffusion and oxidation of Mo were prevented effectively by the coating, which improved the oxidation performance of IC32 significantly.",
