Abstract
A system for use in coating an interior surface of an object is provided. The system includes a vacuum chamber enclosure defining an interior configured to receive the object, and a cathode coupled to the vacuum chamber enclosure. The cathode is fabricated from a coating material and has an outer surface. The cathode is configured such that when a current is applied to the cathode, an arc is formed on the outer surface and the coating material is removed from the cathode to form a cloud of coating material. The system also includes a collimator configured to be positioned between the cathode and the object configured to focus the cloud into a beam of coating material and to direct the beam towards the object, and a magnet configured to alter a path of the beam such that the beam is directed towards the interior surface of the object.
