A gas distribution ring for a plasma gun comprises a ring member with two sets of gas inlet orifices extending from the outer surface inwardly through the ring member. The outer surface has an undulated groove for an O-ring formed therein, and the orifices are positioned with respect to the undulated O-ring such that one set of orifices are isolated on one side of the O-ring and the other set of orifices are isolated on the other side of the O-ring. In a preferred embodiment the orifices of one set are radial with respect to the axis of the ring, and the orifices on the other side of the undulated O-ring have a tangential component to provide vortical gas flow in the arc region of the gun. The gas distribution ring positioned in the plasma spray gun permits a simple choice between radial and vortical flow in the arc region of the gun, without alteration of the gun. |
