    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.

    Abstract: A method of fabricating a component is provided. The component includes a substrate that has at least one interior space. The method includes forming one or more grooves in the component. Each groove extends at least partially along an outer surface of the substrate and narrows at an opening thereof, such that each groove is re-entrant shaped. A cross-sectional area A of each groove is in a range of about 2 to about 3 times an area R=W*D, where W is the width of the opening and D is the depth of the re-entrant-shaped groove. Components with grooves formed in the substrate and components with grooves formed at least partially in a structural coating are also provided.

    Abstract: A plasma deposition assembly for use in coating an interior surface of an object is provided. The assembly includes a head portion including an anode and a cathode adjacent to the anode. The cathode is fabricated from a coating material. The cathode also includes an outer surface adjacent to the interior surface of the object, wherein current is supplied to the cathode to form an arc on the outer surface such that the coating material is directed substantially radially outward from the outer surface of the cathode towards the interior surface of the object. The assembly also includes a moveable arm coupled to the head portion and configured to translate the head portion relative to the interior surface of the object as the arc deposits the coating material on the interior surface of the object.

    Abstract: There is provided a fuel rod assembly comprising a first component of a zirconium-based material. The first component is in contact with or is located adjacent to a second component of a material different from the zirconium-based material, e.g. a nickel-based or iron-based alloy. A coating is disposed on an outer surface of the first component, which is effective to reduce an electrochemical corrosion potential difference between the first component and the second component relative to an electrochemical corrosion potential difference between the first component and the second component without the coating.
