摘要	Magnetron sputter deposition was used to prepare Ni-9.7Cr-5.5Al-7Ti (wt%) nanocrystalline coatings on the substrates of the same material. The oxidation behavior of the cast Ni-Cr-Al-Ti alloy and its sputtered coating at 1000 degrees C in air was investigated. An alpha-Al2O3 scale with TiO2 dispersions was formed on the sputtered coating after 200 h of oxidation; even so good oxidation resistance was exhibited. The formation of TiO2 was attributed to the high ratio of Ti/Al in the coating. The high content of Cr and the precipitation of Ni-3(AlTi) in the sputtered coating during oxidation could restrict the formation and growth of TiO2. Therefore,good oxidation resistance was shown by the sputtered Ni-Cr-Al-Ti coating despite the formation of TiO2. (C) 2000 Elsevier Science S.A. All rights reserved.
