    摘要:

    采用EB-PVD技术在镍基合金Rene N5基体表面沉积NiCrAlY粘结层,并对试样进行1000℃不同时间的恒温氧化处理,通过SEM、EDS、XRD研究了基体与粘接层界面元素互扩散行为和反应区的形成机制。结果表明:在1000℃条件下, NiCrAlY粘结层中的Al、Cr元素会向N5基体扩散,形成以β-NiAl和α-Cr相为主的互扩散反应区;而N5基体中的Ni元素则会向NiCrAlY粘结层扩散,形成以γ’-Ni3Al相为主的二次反应区和以难熔金属为主的TCP相。

    Abstract:

    In this article, NiCrAlY bond coatings was deposited on the Ni-based superalloy (N5) by EB-PVD, and the sample was oxidized by the constant temperature of 1000℃ for different time. Interdiffusion behavior of interface between subatrate and bond coat, as well as, the foramation mechanism of reaction zone was analyaed by SEM、EDS and XRD. The result shows that the elements of Al and Cr in the NiCrAlY coating was diffused to the N5 substrate and formed an interdiffusion reaction zone dominated with β-NiAl phase and α-Cr phase; and the Ni elements in the N5 substrate was diffused to the NiCrAlY coatings, forming the secondary reaction zone and TCP phase, which was mainly composed with the γ’-Ni3Al and refractory metal respectively.
