Abstract NiCrAlY and NiCoCrAlYHfSi coatings were deposited on nickel-based superalloy DZ22B by arc ion plating. The microstructure, composition and high temperature oxidation resistance was compared, and the action of active elements in oxidation was discussed. Results show that the as-deposited coatings were mainly composed of γ′-Ni₃Al/γ-Ni,β-NiAl, and α-Cr, and the addition of NiCoCr in NiCoCrAlYHfSi. After the heat treatment, the transformation of β-NiAl to γ′-Ni₃Al occurred. The average oxidation rates of NiCrAlY and NiCoCrAlYHfSi coatings after 200 h were 0.072 3 g/(m²·h) and 0.052 7 g/(m²·h) at constant tempe-rature of 1 050 ℃. The α-Al₂O₃,NiCr₂O₄ and Cr₂O₃ phase firstly formed at the initial stage of oxidation of NiCrAlY. Cracks, holes and other defects were subsequently observed and the oxide extended to the interior of the coating along those defects. At the same time, TiO₂ formed as a result of the diffusion of Ti in substrate. For NiCoCrAlYHfSi oxidation, metastable θ-Al₂O₃ formed at the initial stage and then transferred to stable α-Al₂O₃. The oxide layer is more uniform and dense compared to NiCrAlY, thus has better oxidation resistance.
