Abstract:
A plasma-enhanced coaxial magnetron sputter-cleaning and coating assembly for sputter-cleaning and coating the interior surfaces of a cylindrical workpiece with a cylindrical sputtering material, the cylindrical sputtering material having an interior and an exterior, and the apparatus comprising:i. a core cooling system surrounded by a ring magnet assembly including a plurality of axially aligned ring magnets, with the core cooling system and the ring magnet assembly axially aligned with, and residing in the interior of, the cylindrical sputtering material; ii. a cylindrical-shaped filament circumferentially surrounding the exterior of the cylindrical sputtering material; and iii. an anode comprised of a wire screen circumferentially surrounding, and external to the filament; whereby the apparatus for plasma-enhanced coaxial magnetron sputter-cleaning and coating may be housed inside the workpiece in order to sputter-clean and coat the interior of the workpiece.
