Abstract Scope We are reporting development of a class of metal/ceramic based multilayer coatings which have successfully demonstrated a significant hydrogen impermeability at high operating temperature (up to 500 oC). These coatings have been manufactured using atomic layer deposition (ALD) and physical vapor deposition (PVD) techniques. This presentation will be highlighting two aspects of the developed barrier coating: (a) thermal cycling stability; and (b) reduction of hydrogen permeation rate. To understand the overall effect from thermal cycling on H2 permeation –five repetitive cycles of heating from 25 °C to 500 °C – were conducted. Our study focused upon features such as: (a) structural properties of coating materials that included grain structure (columnar or equiaxed) and crystalline or amorphous phases; (b) coating interface (e.g., amorphous/crystalline, amorphous/amorphous, crystalline/crystalline; and metal/ceramic and (c) coating material chemistry (e.g., metal, metal oxides). Additionally, potential application of this coating in high temperature micro nuclear reactors will be discussed.
