- 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. •Ru–Si–Zr multilayer coatings formed an amorphous structure from Si addition.•Annealed Ru–Si–Zr multilayers formed repeated ZrO2-, Ru-, and SiO2-dominant stacks.•Ru–Si–Zr multilayers restricted the outward diffusion of elements from Inconel 617.•Ru-Al multilayers restricted the inward diffusion of O from ambient air.
