  • Methods for manufacturing nanostructured and compositionally-tailored tubes and components by low temperature, solid-state cold spray powder deposition
    Patent number: 11598008
    Abstract: Disclosed is a method for manufacturing free-standing cladding tubes with multi-layer structures. According to the method, a cylindrical mandrel substrate defining a hollow cylindrical inner space is provided. A first cold spray powder metal is selected. The cylindrical mandrel substrate is rotated and the first cold spray powder metal is applied to an outer surface of the cylindrical mandrel substrate to form a first layer. The cylindrical mandrel substrate is removed.
    Type: Grant
