DIRECTIONAL COLD SPRAY NOZZLE

摘要

A directional cold spray nozzle defines a flow passageway that includes a bend for redirecting flow from a first flow direction to a second flow direction different from the first flow direction, wherein the flow passageway is divergent through at least a portion of the bend. The flow passageway may be convergent prior to becoming divergent in the path of flow. The directional cold spray nozzle simultaneously accelerates the powder and carrier gas and changes the spray direction of the spray plume to reach interior bore surfaces and other surfaces that are difficult or impossible to reach with a straight nozzle.
