Abstract
A plasma spray system including a turntable subsystem operable to position a multiple of work pieces on a respective multiple of workpiece mounts; 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.
Claims18
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.

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.
