Abstract: A system for coating a component is provided. The system includes a feedstock supply, a carrier fluid supply, and a thermal spray gun coupled in flow communication with the feedstock supply and the carrier fluid supply. The feedstock supply contains a substantially homogeneous powder mixture of a first powder and a second powder. The second powder is softer than the first powder and has a percentage by mass of the powder mixture of between about 0.1% and about 3.0%.

Abstract: A method for joining a ceramic component to a metallic component is described. At least one layer of molybdenum is applied to a surface of the ceramic component, by a high-velocity molybdenum wire spray technique. A layer of a nickel-based braze composition is then applied over the molybdenum layer. The braze composition and the ceramic and metallic components are then heated to a sufficient brazing temperature, so as to provide a braze joint between the components. The method can be used to seal an open region of a thermal battery, e.g., a sodium metal halide-based battery.

Abstract: A method for repairing a Ni-based alloy component includes preparing a surface of the Ni-based alloy component for receiving a cold spray repair; spraying a stream of particles onto a the surface of the Ni-based alloy component to form a coating thereon; and removing any over-spray on the surface of the Ni-based alloy component. The particles are formed from an alloy material having a melting point such that the particles are sprayed at a spray temperature that is less than the melting point of the alloy material.

Abstract: A method for joining a ceramic component to a metallic component is described. At least one initial layer of an active metal is applied to one of the joining surfaces, by a cold spray technique. At least one second layer of a nickel-based braze composition is then applied over the initial layer by cold-spraying. The braze composition and components are then heated, so as to form an active braze joint between them. A method of sealing an open region of a sodium metal halide-based battery is also disclosed, using the brazing technique described herein to form braze joints that seal various components in the battery cells, such as metallic rings and ceramic collar structures.
