摘要	Oxidation behavior of a Ta-containing nanocrystalline coating with different contents of Y and Al on the N5 single-crystal superalloy is investigated at 1050 and 1150 degrees C. Results indicate that the refractory element, Ta, is very active during oxidation. It diffuses easily from the interior of the nanocrystalline coating to the interface of coating/scale in the form of gamma'-Ni-3(Al, Ta), where it is oxidized and ruins the compactness of oxide scale. Adding moderate amount of Y retards the movement and oxidation of Ta, thus increases oxidation resistance. Such retarding effect is strengthened by increasing Al content, while weakened by increasing temperature.; Oxidation behavior of a Ta-containing nanocrystalline coating with different contents of Y and Al on the N5 single-crystal superalloy is investigated at 1050 and 1150 degrees C.
