| Abstract: |
An HVOF extension gun for spraying internal diameters down to 5 inch (127 mm) has been developed and evaluated. The spray gun utilizes novel stabilization of the flame which permits operation with a minimal length combustion chamber. Short spray distances and subsequent reduced particle dwell times present a challenge for melting and accelerating powders to achieve typical HVOF coating benchmark properties such as hardness, density and residual stress. Initial coating characteristics and process/system capabilities are discussed.
