| 英文摘要 | The isothermal oxidation behavior of Hastelloy N superalloy with different silicon contents at 850 degrees C in air was investigated by a discontinuous increasing weight method. The results show that oxidation mass gain kinetics of the samples follows the parabolic law with increasing Si contest. It is observed that the surfaces of the alloys exhibit a multi-layer structure after 100 h oxidation. The outer oxide film of Hastelloy N superalloy mainly consists of NiO, NiFe2O4 and other oxide composites. The middle layer is confirmed to be Cr2O3 and MoO2. A continuous and dense SiO2 sublayer is formed at the metal-oxide interface, it is effective to prevent Cr diffusion. The addition of Si promotes the formation of a relatively continuous and compact Cr2O3 and it can strongly improve the oxidation resistance. |
