Abstract

MCrAlY coatings were deposited on Ni-based IC6 superalloy by HVOF (high velocity oxy-fuel), and the ZrO2 coatings were prepared using plasma spray technique. The oxidation kinetic curves of the IC6 superalloy were obtained after the heat treatment. The results indicated that the oxidation resistance of IC6 superalloy was markedly improved by coatings with MCrAlY and MCrAlY+ZrO2. The oxidation product of the MCrAlY coating mainly consisted of α-Al2O3,NiO at 1100°C, oxidation product was not found on the MCrAlY+ZrO2 coating at 1100°C.
