Abstract: A method for forming a protective coating on a substrate comprising, applying a bond coating to the substrate, the bond coating having a first surface roughness, ionizing an inert gas which flows into the surface of the bond coating so as to impart a second surface roughness to the bond coating greater than the first surface roughness, wherein the inert gas is ionized and caused to flow into the surface of the bond coating by a reverse polarity current supplied to an electrode which removes at least one electron from the inert gas, and applying a top coating to the bond coating. Additionally, a method for preparing a surface to receive and adhere to a coating comprising roughening the surface to create a micro-roughening network on the surface. In addition, a method of improving strain tolerance and cyclic spallation life of a protective coating.

Abstract: A coating for turbomachinery comprises graphite-based sold film lubricant material.

Abstract: An airfoil assembly for a turbine engine, that may comprise: an airfoil that includes at least one panel opening formed therein; and an aperture panel that includes at least one cooling aperture; wherein the panel opening and the aperture panel are configured such that, upon installation of the aperture panel within the panel opening, a substantially smooth outer surface of the airfoil is formed and at least one of the cooling apertures of the aperture panel forms an exit passageway from at least one hollow internal cavity within the airfoil.

Abstract: Process for providing a protective coating to a metal surface by applying a nickel or tantalum plate layer to the surface and dispersing particles of a hard material such as diamond, alumina, vanadium nitride, tantalum carbide and/or tungsten carbide within the nickel or tantalum plate layer as the plating is occurring.

Abstract: A thermal barrier coating (TBC) system is provided. The system includes at least one thermal barrier coating (TBC) bond coat layer formed over a substrate surface region. The TBC bond coat layer includes at least one TBC bond coat material. The TBC bond coat material is a nickel-chromium-aluminum-yttrium (NiCrAlY) composition that also includes silicon (Si), hafnium (Hf) and less than 10 weight percent (wt %) cobalt (Co). The TBC system further includes at least one top coat layer formed over the TBC bond coat layer.

Abstract: A method of sealing gaps between a bucket dovetail and a rotor disk dovetail slot in which the bucket dovetail is adapted to be received, the method comprising applying a resin material to selected areas of the bucket dovetail; and inserting the bucket dovetail into the dovetail slot.

Abstract: A method and apparatus is described for enabling the testing and evaluation of industrial machine components and, in particular, gas turbine engine components, under simulated in-situ thermal operating conditions for effectively evaluating new component designs and repair techniques. A specimen machine component/part is placed in a test chamber and cyclically heated and cooled while being monitored to obtain information regarding the initiation and propagation of a crack within the structure of the component. Information regarding the number of heating and cooling cycles sustained by the component until crack initiation and information indicating the rate of crack propagation are acquired and compared over multiple heating-cooling cycles to evaluate components and repair techniques.

Abstract: A method of welding superalloy components comprising: preheating one or more components to be welded to a target temperature of at least 1500OF in a vacuum chamber; welding the one or more preheated components in a weldment region utilizing an electron beam, while maintaining the target temperature until welding is completed.

Abstract: A project tracking system includes a user interface includes a project window, a request window, and a task window, categorizing project related information, request related information and task related information, respectively. The project window is formatted to display project level information, a funding summary and a request list. The request window is formatted to display request level information and a list of user selectable tasks. The task window can be formatted to display task level information and a list of invoices. The system can determine if a user has authority to modify project level, request level, or task level information before allowing the user to modify such information in a number of fields in the corresponding project, request and task windows. Each of the project, request, and task windows can be a different appearance, such as a different color background.

Abstract: An adjustable bracket for mounting a jamb to an adjacent framing member. The mounting assembly comprises at least one L-shaped member, an inner leg of which is secured to the back of the jamb. The outer leg of the member can be nailed to the surrounding framing to locate and support the jamb.In one embodiment, a pair of telescoping L-shaped members are provided, one of which is secured to the jamb while the other slides within it. The members are advantageously formed with stiffening means at the apexes, and can be formed with detents for engaging the opposite edges of a hollow molding strip.In another embodiment, the brackets engage one side of the molding strip, the other side thereof being forced into a slot extending along the door jamb. A retainer is described which aids in retaining the molding lip in the jamb slot.
