Temperature Effect on Early Oxidation Behavior of NiCoCrAlY Coatings:Microstructure and Phase Transformation
文献摘要:
Initial oxidation behavior of NiCoCrAlY coating prepared by arc-ion plating has been studied in air at 900,1000 and 1100℃.The results showed that phase transformation from transient θ-Al2O3 to α-Al2O3 was highly related to the temperature and oxidation time.The oxide scale in the initial stage was mainly composed of θ-Al2O3 at 900℃.Instead,more amount ofα-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 θ-Al2O3 to α-Al2O3.Y segregation at scale/coating interface resulted in less cavity formation and hence improved the oxide scale adherence.
