Abstract: A nozzle assembly (48) for a kinetic spray system includes a convergent portion (72) , a throat portion (82) , and a divergent portion (76) , each cooperating together to define a passage (66) therethrough for passing a mixture of powder particles (22) suspended in a flow of a high pressure heated gas. The nozzle assembly (48) further includes an extension portion (86) attached to the divergent portion (76) and extending to a distal end (88) a pre-determined length (L) from the divergent portion (76) of the nozzle assembly (48) . The extension portion (86) permits a dragging force exerted on the powder particles (22) by the flow of high pressure heated gas to act upon the powder particles (22) for a longer duration of time, thereby permitting the powder particles (22) to accelerate to a greater velocity than has been previously achievable.
