Abstract

NiCoCrAlYSi/NiCoCrAlY gradient coatings were deposited on Ni₃Al based single crystal alloy IC6SX-by HVOF method, and the oxidation resistance of the coated alloy at 1100°C were investigated. The microstructure of the samples before and after oxidation were examined by SEM and XRD. The results showed that double layers oxidation scales compactly formed on the surface of the coatings. The inner layer was mainly composed of Al₂O₃. The outer layer was composed by NiAl₂O₄ and a small amount of Cr₂O₃. The diffusion and oxidation of Mo were prevented effectively by coatings, which improved the oxidation of the alloy IC6SX significantly.
