a plasma spray subsystem operable to plasma spray the multiple of work pieces on said turntable subsystem; and an overspray wash subsystem operable to wash the multiple of work pieces on said turntable subsystem subsequent to plasma spray of the multiple of work pieces. ## Claims ### Claim 1 A plasma spray system, comprising: a turntable subsystem operable to position a multiple of workpieces on a respective multiple of workpiece mounts about a central axis; a plasma spray subsystem directed toward said central axis, said plasma spray subsystem operable to respectively plasma spray each of the multiple of workpieces on said turntable subsystem in response to rotation of said respective multiple of workpiece mounts about the central axis; and an overspray wash subsystem positioned relative to the plasma spray subsystem, said overspray wash subsystem operable to respectively wash the multiple of workpieces in response to rotation of said respective multiple of workpiece mounts about the central axis. ### Claim 2 (depends on 1) The system as recited in claim 1, wherein said overspray wash subsystem is positioned relative to said plasma spray subsystem by about thirty to three hundred and thirty (30-330) degrees of said turntable subsystem rotation. ### Claim 3 (depends on 1) The assembly as recited in claim 1, wherein each of said multiple of workpiece mounts are rotatable about a respective axis parallel to said central axis. ### Claim 4 (depends on 3) The assembly as recited in claim 3, further comprising a sun drive that rotates a removable saucer of said turntable subsystem about said central axis and a planetary drive that selectively rotates said multiple of workpiece mounts. ### Claim 5 (depends on 3) The assembly as recited in claim 3, further comprising a deflector located about said central axis and within said multiple of workpiece mounts. ### Claim 6 (depends on 5) The assembly as recited in claim 5, wherein said deflector is multi sided. ### Claim 7 (depends on 1) The assembly as recited in claim 1, further comprising a wall collector adjacent to said turntable subsystem opposite said plasma spray subsystem. ### Claim 8 (depends on 1) The assembly as recited in claim 1, wherein said overspray wash subsystem is operable to wash the multiple of workpieces with dry ice. ### Claim 9 (depends on 8) The system as recited in claim 8, wherein said overspray wash subsystem is positioned relative to said plasma spray subsystem by about thirty to three hundred and thirty (30-330) degrees of said turntable subsystem rotation. ### Claim 10 (depends on 1) The system as recited in claim 1, further comprising a multiple of turntable subsystems. ### Claim 11 (depends on 10) The system as recited in claim 10, wherein said plasma spray subsystem rotates between at least two of said multiple of turntable subsystems. ### Claim 12 A plasma spray system, comprising: a turntable subsystem operable to rotate a multiple of workpieces on a respective multiple of workpiece mounts, said turntable subsystem rotatable about a central axis and each of said multiple of workpiece mounts are rotatable about a respective axis; a plasma spray subsystem operable to plasma spray the multiple of workpieces on said turntable subsystem as said turntable subsystem rotates said multiple of workpieces about said central axis, said plasma spray subsystem arranged to spray in a direction transverse to the central axis; and an overspray wash subsystem operable to wash the multiple of workpieces on said turntable subsystem, said overspray wash subsystem downstream of said plasma spray subsystem with respect to rotation of said turntable subsystem about said central axis. ### Claim 13 (depends on 12) The assembly as recited in claim 12, wherein said overspray wash subsystem is operable to wash the multiple of workpieces with dry ice. ### Claim 14 (depends on 12) The system as recited in claim 12, wherein said plasma spray subsystem rotates between at least two of a multiple of turntable subsystems. ### Claim 15 (depends on 1) The system as recited in claim 1, wherein said overspray wash subsystem is directed toward said central axis and positioned at an angle relative to the plasma spray subsystem. ### Claim 16 (depends on 15) The system as recited in claim 15, wherein said overspray wash subsystem is positioned at an angle relative to the plasma spray subsystem. ### Claim 17 (depends on 1) The system as recited in claim 1, wherein said plasma spray subsystem is directed to spray in a direction transverse to the central axis. ### Claim 18 (depends on 17) The system as recited in claim 17, wherein said overspray wash subsystem is directed to spray in a direction transverse to the central axis.
