研究了Ni-11Fe-10Cu-6Al合金在750、850和950℃空气中的高温氧化行为。其氧化动力学在所有温度下均遵循抛物线速率规律，明显低于Ni-11Fe-10Cu和Ni-11Fe-10Cu- 6al - 3y合金的氧化动力学。在Ni-11Fe-10Cu合金中掺入Al不仅可以提高氧化皮的附着力，还可以提高合金的抗氧化性。研究了Ni-11Fe-10Cu-6Al合金上形成的多层氧化皮的结构和生长机理。讨论了Al掺杂对Ni-11Fe-10Cu合金高温氧化行为的影响。
The high-temperature oxidation behavior of Ni-11Fe-10Cu-6Al alloy at 750, 850 and 950 degrees C in air was investigated. Its oxidation kinetics follow the parabolic rate law at all temperatures and are significantly lower than those of Ni-11Fe-10Cu and Ni-11Fe-10Cu-6Al-3Y alloys. The doping of Al to Ni-11Fe-10Cu alloy can improve not only the adherence of oxide scale but also the oxidation resistance. The structure and growth mechanism of multilayer oxide scale formed on Ni-11Fe-10Cu-6Al alloy are studied. The effect of doping Al on the high-temperature oxidation behavior of Ni-11Fe-10Cu alloy is also discussed.
