摘要	NiCrAlY coating was deposited on a single crystal Ni-base superalloy by detonation gun spraying. By means of XRD, SEM and EDS, isothermal oxidation behavior of the coatings at 1050 degreesC were studied. The results showed that detonation gun sprayed NiCrAlY coatings held a favorable oxidation resistance. Their oxidation kinetics at 1050 degreesC obeyed the parabolic law. alpha-Al2O3 scale was formed on the coating surface and kept almost intact after oxidation for 300 It. Internal oxidation led to the formation of Al2O3 at the coating/substrate interface, and needlelike (Al, N) compounds appeared in the undersurface area of the substrate.
