| 摘 要： | 采用电子束物理气相沉积技术制备了微晶氧化物弥散增强Ni基高温合金,并研究了该合金的高温氧化行为.通过最小二乘拟合得到的合金氧化动力学模型近似遵循4次方规律,并在高温氧化过程中,合金能够生成单一的Al2O3氧化膜,而且氧化膜的粘附性好,不易脱落.稀土氧化物的添加可明显地改善合金的抗高温氧化性能,提高氧化膜的粘附性.

| Abstract: | The high temperature oxidation behavior of oxide dispersion strengthened Ni-based superalloy prepared by electron beam physical vapor deposition was investigated.The oxidation kinetics of this superalloy was derived to obey the forth power law approximately.This oxide scale composed of pure Al_2O_3 has a good adhesion ability,no spallation was found during the high temperature oxidation.The oxidation resistance of this alloy and adhesion of oxide scale was increased by adding of rare earth oxide. |

| Keywords: | electron beam physical vapor deposition oxide dispersion strengthened superalloy high temperature oxidation oxide scale |
