Abstract:

热障涂层中黏结层的氧化性能与其成分及其组织结构有关,该文采用超音速火焰喷涂方法制备NiCoCrAlTaY涂层和CoNiCrAlY黏结层,通过组织结构研究和氧化性能试验,研究不同成分的黏结层对超音速火焰喷涂MCrAlY黏结层氧化性能的影响,以及热生长氧化物(thermallygrownoxides,TGO)的生长机理。研究结果表明超音速火焰喷涂过程中,MCrAlY粉末发生了氧化,黏结层中含有大量半球形粒子。两种涂层氧化25h前TGO以Al2O3为主,氧化100h后,在Al2O3膜表面出现了大量的Ni/Cr/Co氧化物。CoNiCrAlY涂层氧化动力学系数为0.272μm/h1/2,略低于NiCoCrAlTaY涂层。Ni/Cr/Co氧化物的形成取决于Ni、Cr、Co等元素的扩散速度和Al2O3膜的生长速度。
