ABSTRACT:
A nozzle is provided for use during a process for cold-dynamic gas spraying a powder material onto a bore surface. In one embodiment, and by way of example only, the nozzle includes a tube and a coating. The tube is configured to direct the powder material to the bore surface and has an inner surface, an axial section, a radial section, and a bend. At least a portion of the inner surface of the axial section defines a converging/diverging flowpath, and the axial section and the radial section are disposed at a predetermined angle relative to one another and include the bend disposed therebetween. The coating is disposed on at least a portion of the tube inner surface and comprises a material to which the powder material does not adhere.
