| 英文摘要 | The normal spectral emissivity of ni-based alloy k465 during oxidation is experimentally measured at 810, 914 and 998 degrees c for 12 h in air over the wavelength from 1.3 to 2.4 mu m. the combined standard uncertainty of the normal spectral emissivity is less than 3%. the oscillations of the emissivity and the effects of oxidation temperature, heating time and wavelength on the emissivity are investigated. the oscillations of the emissivity are formed by the interference effect between the radiation from the surfaces of the substrate and the oxidation film. the oscillation extremums of the emissivity shift towards larger wavelengths as the oxidation process proceeds. the results show that the normal spectral emissivity increases as the temperature increases at the initial time. the normal spectral emissivity decreases as wavelength increases except for the occurrence of the oscillations of the emissivity. the normal spectral emissivity increases rapidly at the initial heating time, and the change of emissivity becomes slow when the oxidation tends to be saturated gradually. besides, the emissivity fitting models versus heating time and wavelength are established, which fit the experimental results very well. the emissivity relative errors of the fitting models are less than 4%.
