A process for joining dissimilar materials. The process includes providing a first component made from a first material and a second component made from a second material. The process also includes cold spraying a bead of the second material onto the first component and joining the second component to the bead on the first component such that a weldment is formed from the first component and the second component. In some instances, joining of the second component to the bead on the first component is performed by fusion welding the bead and the second component together.

A pressure vessel fluid manifold assembly includes a pressure vessel having a plurality of lobes joined to each other, each of the plurality of lobes having a wall disposed in contact with an adjacent wall of an adjacent lobe, and wherein the manifold can be external or internal to the lobes.

An atomizing spray device includes a housing having plural inlets and one or more outlets fluidly coupled with each other by an interior chamber. The inlets include a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid. The interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets. The interior chamber in the housing also is shaped to direct the mixture formed inside the housing as droplets outside of the housing via the one or more outlets such that, based on a discharged amount of the first fluid in the droplets, the first fluid promotes evaporation of the second fluid as the droplets traverse from the housing toward a surface of a component.

A conformable tank includes a body with a plurality of composite walls formed around a cavity, and an internal support connected to one of the plurality of composite walls and positioned in the cavity. The plurality of composite walls includes a flat side wall disposed opposite a curved side wall. A first section of one of the plurality of composite walls includes an exterior facing, an interior facing, and a core positioned between the exterior facing and the interior facing.

Conformable tank with sandwich structure walls

A conformable tank includes a body with a plurality of walls defining a cavity in the body, and an internal support connected to an internal surface of one of the plurality of wall of the body and protruding into the cavity of the body. The body and the internal support are an additively manufactured integral structure formed by a fiber filament reinforced composite material.

A powder feeder for a cold spray system includes a rotatable drum body, a housing surrounding the drum body, and a support structure. The support structure couples to the housing and supports the housing such that the drum body rotates about a rotation axis to provide in-situ blending of powder disposed within an interior of the drum body.

A portable gas heater includes a housing, a pressure vessel arranged in the housing, a layer of thermal insulation disposed on an interior wall of the pressure vessel, a heating element arranged within the layer of thermal insulation, and a gas diffuser arranged upstream from the heating element. A cold spray system including the portable gas heater and a method of heating gas are also disclosed.

High temperature and high pressure portable gas heater

A cold spray nozzle assembly includes a conduit for carrying at least one of a heated gas and a powder; a nozzle; and a compression tube fitting connecting the nozzle to the conduit.
