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.

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.

The present disclosure is directed to the use and manufacture of cooling features within a component used in a hot gas path, such as within a turbine. In one embodiment, channels are formed within an external surface of the component and filled with a removable material. The external surface and channels may then be coated with one or more layers, such as a structural layer and/or top coat. The removable material may then be removed to leave the channels free of the removable material.

A gate valve has a body, the body having a cavity and a flow passage intersecting the cavity. A seat is mounted to the body at the intersection of the flow passage and the cavity. A gate is installed at the cavity and has an engaging face that slidingly engages the seat while the gate is being moved between open and closed positions. The end faces between a seat pocket and the seat are hard-coated and smooth-finished to provide sealing when mated. The hardcoated pocket and seat sealing surfaces extend the life of the valve by eliminating the need for an elastomeric seal of limited life.
