中文摘要: 飞机发动机及燃气轮机的发展要求更高的燃气进口温度， 从而获得更高的推重比或功率输出， 抗氧化
MCrAlY 涂层在其中发挥至关重要的作用。 本文采用含有 Ta 元素的 Amdry997 粉末进行超音速火焰喷涂， 研究涂
层的高温氧化行为， 并重点关注Al和Ta元素在涂层内不同相中的分布， 及其对涂层与基体元素互扩散行为的影响。
研究表明， Ta 元素对提高 γ'-Ni3(Al,Ta) 相稳定性起到重要作用。
Abstract:The development of air engines and gas turbines requires higher combustion and turbine temperatures
for higher propulsion force or power generation. More durable and oxidation resistant MCrAlY coatings are then
needed. In this study, Amdry997 powders containing Ta was used for HVOF spray. The high-temperature oxidation
behavior of the coatings was studied by focusing on how Al and Ta elements were distributed in different phases
of the coating and their influence on the interdiffusion behavior of elements between the coating and substrate. The
results showed that the addition of Ta in the coatings increased the stability of γ'-Ni3(Al,Ta) phase.
