Abstract:
A plasma jet CVD system for depositing a diamond coating on a substrate surface of an object, comprising:a) a plasma jet system having a means for producing a diamond coating producing plasma jet and a distribution head through which said plasma jet exits, said distribution head defining a jet axis; b) a mandrel defining a plane on which the object is positionable and a central mandrel axis perpendicular to said plane; c) a deflector having a deflecting surface intersecting said jet axis and angled relative to both said jet axis and said plane, said deflector causing said plasma jet exiting said distribution head to deflect away from said mandrel axis; and d) a deposition chamber surrounding at least a portion of said distribution head, said mandrel, and said deflector, wherein at least one of said deflector and said mandrel rotates about an axis which is normal to said plane.
