Claim 16:
17. A plasma spray apparatus (110) for projecting a deflected particle stream (90) onto a surface (80), said plasma spray system (100) comprising:
a plurality of gases (510) that includes a plasma gas (512) and a secondary gas (518);
a wire (310) that includes a free end (370);
a cathode (212);
a horizontal plane perpendicular to said wire (310) in which said cathode (212) rotates around said free end (370) of said wire (310) while said plasma arc (60) melts said free end (370) of said wire (310); and
a nozzle (220) that includes a nozzle face, an opening (224) in said nozzle face, and a non-symmetrical nozzle passageway configuration (249) that includes a non-symmetrical nozzle passageway (240), said non-symmetrical nozzle passageway configuration (249) causing said secondary gas (510) to horizontally deflect said deflected particle stream (90) in a deflection direction (94) within said plane of rotation that is either (a) in the same direction as the movement of said cathode (212) or (b) in the opposite direction as the movement of said cathode;
wherein said plasma gas (512) is directed to said cathode (212) to create a plasma arc (60) between said free end (370) of said wire (310) and said cathode (212);
wherein said deflected particle stream (90) is a horizontally deflected particle stream (91).
