| 英文摘要 | Initial oxidation behavior of NiCoCrAlY coating prepared by arc-ion plating has been studied in air at 900, 1000 and 1100 degrees C. The results showed that phase transformation from transient theta-Al2O3 to alpha-Al2O3 was highly related to the temperature and oxidation time. The oxide scale in the initial stage was mainly composed of theta-Al2O3 at 900 degrees C. Instead, more amount of alpha-Al2O3 emerged out with increasing oxidation temperature. The elemental distribution after oxidation confirmed that faster chromium diffusion to the oxide scale played an important role in the speedy transformation from theta-Al2O3 to alpha-Al2O3. Y segregation at scale/coating interface resulted in less cavity formation and hence improved the oxide scale adherence. |
