    Abstract: Some embodiments relate to an apparatus for holding a workpiece under tension while one or more operations are performed on the workpiece, the apparatus comprising: a frame; a first spindle rotatably coupled to the frame; a first coupler configured to couple the first spindle to a first end of the workpiece; a second spindle rotatably coupled to the frame; and a second coupler configured to couple the second spindle to a second end of the workpiece; wherein a distance between the first and second couplers is adjustable to hold the workpiece under tension between the couplers while the one or more operations are performed, and wherein the workpiece can be rotated with the couplers relative to the frame about a common axis of rotation extending between the couplers. Some embodiments relate to a system comprising a controller for controlling rotation of the workpiece. Embodiments also relate to processes comprising holding a workpiece under tension while performing one or more operations on the workpiece. Some of the processes, systems and apparatuses described may be particularly useful for cold spraying delicate workpieces such as 3D printed static mixers.

    Abstract: A process for producing a preform by cold spray deposition, the process comprising: providing a starter substrate about a preform axis of rotation, the starter substrate having at least one axial end having a substantially flat deposition surface; rotating the starter substrate about the preform axis of rotation; depositing material onto the deposition surface of the starter substrate using cold spray deposition to form a product deposition surface, the cold spray deposition process including a cold spray applicator through which the material is sprayed onto the deposition surface; successively depositing material onto a respective top product deposition surface using cold spray deposition to form successive deposition layers of the material; and moving at least one of: the cold spray applicator; or the starter substrate and preform product, relative to the other in an axial direction along the preform axis of rotation to maintain a constant distance between the cold spray applicator and the top product deposition surface, thereby forming a preform product of a selected length, wherein the cold spray applicator is moved in a plane perpendicular to the preform axis of rotation so as to deposit material as a substantially flat surface on each respective deposition surface of the starter substrate or product deposition surface of the preform product.
