The feasibility of using Ru–Si–Zr multilayer and laminated Ru–Al/Ru–Si–Zr multilayer coatings as bond coats of thermal barrier systems for Inconel 617 was investigated by annealing the coatings at 800 °C in ambient air. The multilayer coatings were fabricated through the deposition of a cyclical gradient concentration by using cosputtering. The thermal stability of the annealed coatings was examined using X-ray diffraction, transmission electron microscopy, and Auger electron spectroscopy. The results indicated that Ru–Si–Zr multilayer coatings restricted the outward diffusion of metallic elements from Inconel 617 substrates, and an additional coating of an Ru-Al multilayer above the Ru–Si–Zr multilayer restricted the inward diffusion of oxygen from ambient air.

通过在环境空气中在800°C下退火，研究了使用Ru-Si-Zr多层和Ru-Al / Ru-Si-Zr多层层压涂层作为Inconel 617热障系统的粘结涂层的可行性。通过使用共溅射沉积周期性梯度浓度来制造多层涂层。使用X射线衍射，透射电子显微镜和俄歇电子能谱检查了退火涂层的热稳定性。结果表明，Ru-Si-Zr多层涂层限制了金属元素从Inconel 617基板向外扩散，Ru-Si-Zr多层之上的Ru-Al多层涂层限制了氧气从周围空气中的向内扩散。 。
