<p>An inside diameter spray grun is provided which includes an axial gas stream for propelling molten material in an axial direction away from an arc region (37), and a pocket-shaped transverse gas stream (42) which intersects the axial gas stream at a location downstream of the arc region and serves to capture and redirect the molten material at an angle generally perpendicular to the axial direction. The arc spray gun may, therefore, be used to produce a spray coating within tight spaces or inside diameter surfaces of the workpiece intended to be coated. The pocket-shaped gas stream may emanate from a cup-shaped (33), V-shaped (33'), open-box shaped (33'') other pocket shaped orifice located in the arc head of the arc spray gun. The pocket-shaped gas stream serves to capture and redirect the molten material while controlling the dispersion thereof.</p> |
