Abstract
Official abstract text for this publication.
A nozzle for a cold spray deposition apparatus includes a convergent section defined about a nozzle inlet, a divergent section defined about a nozzle outlet, and a surface treatment that projects from an exterior of the divergent section, where an interior of the divergent section conveys a powder material received from the convergent section.
First claim
Opening claim text (preview).
What is claimed is: 1 . A nozzle for a cold spray deposition apparatus, comprising: a convergent section defined about a nozzle inlet; a divergent section defined about a nozzle outlet; and a surface treatment that projects from an exterior of the divergent section, wherein an interior of the divergent section conveys a powder material received from the convergent section. 2 . The nozzle of claim 1 , wherein the surface treatment includes at least one ridge. 3 . The nozzle of claim 2 , wherein the at least one ridge includes a plurality of ridges. 4 . The nozzle of claim 3 , wherein the ridges are distributed around a circumference of the divergent section. 5 . The nozzle of claim 3 , wherein each of the ridges runs substantially parallel along a longitudinal axis of the divergent section. 6 . The nozzle of claim 2 , wherein the at least one ridge is shaped as at least one of a coil, a helix, or a spiral. 7 . The nozzle of claim 1 , wherein the surface treatment includes a plurality of pin fins. 8 . The nozzle of claim 7 , wherein adjacent pin fins of the plurality of pin fins are equidistantly spaced from one another. 9 . The nozzle of claim 7 , wherein a first pin fin and a second pin fin of the plurality of pin fins are spaced from one another by a first distance, and wherein the second pin fin and a third pin fin of the plurality of pin fins are spaced from one another by a second distance, and wherein the first pin fin and the second pin fin are adjacent to one another, and wherein the second pin fin and the third pin fin are adjacent to one another, and wherein the second distance different from the first distance.
