Abstract
A nozzle assembly for a kinetic spray system includes a convergent portion, a throat portion, and a divergent portion, each cooperating together to define a passage therethrough for passing a mixture of powder particles suspended in a flow of a high pressure heated gas. The nozzle assembly further includes an extension portion attached to the divergent portion and extending to a distal end a pre-determined length from the divergent portion of the nozzle assembly. The extension portion permits a dragging force exerted on the powder particles by the flow of high pressure heated gas to act upon the powder particles for a longer duration of time, thereby permitting the powder particles to accelerate to a greater velocity than has been previously achievable.
