ABSTRACT:
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.
