| 英文摘要 | To investigate the oxidation behavior of a nickel-based superalloy with high hafnium content(1.34wt%),this study performed isothermal oxidation tests at 900,1000,and 1100°C for up to 200 h. X-ray diffraction and scanning electron microscopy with energy-dispersive X-ray spectroscopy were applied to study the oxidation behavior. The weight gain of the high Hf nickel-based superalloy exhibited a parabolalike curve,and no spallation of the oxide scale was observed during the oxidation tests. The alloy presented excellent oxidation resistance,and no HfO_2 was observed in the oxide scale at 900°C. With the increase of the oxidation temperature to 1000°C,HfO_2 particles formed in the spinel phases of the scale,and peg-like HfO_2 was observed within and beneath the inner layer of Al_2O_3 after 200 h. As the oxidation temperature rose to 1100°C,peg-like HfO_2 was observed at the early stage of the oxidation test(within 25 h). The formation mechanism of HfO_2 and its impact on oxidation resistance were investigated based on the analysis of the oxidation test results at different temperatures. |
