摘要: A spray apparatus includes a body having an outer surface and an interior portion, and a first nozzle arranged in the interior portion of the body. The first nozzle includes a first material inlet, a first convergent region, a first throat region, a first divergent region, and a first outlet. The first throat region and first outlet establish a first expansion ratio. A second nozzle is arranged in the interior portion of the body adjacent the first nozzle. The second nozzle includes a second material inlet, a second convergent region, a second throat region, a second divergent region, and a second outlet. The second throat region and the second outlet establish a second expansion ratio that is distinct from the first expansion ratio.

摘要: A spray coating process and apparatus suitable for depositing coatings on surfaces of components, and particularly surfaces that are difficult to access with conventional cold spraying equipment. The process and apparatus employ a spray gun having a tubular body with a longitudinal axis and an exit at one end thereof. The body has a first portion defining a converging passage, a second portion defining a diverging passage that defines the exit of the body, and a throat portion therebetween that defines a throat between and connecting the converging and diverging passages. The gun is further equipped with at least one gas inlet for introducing a gas upstream of the converging passage, and at least one feedstock inlet for introducing a feedstock at or immediately upstream of the throat.
