摘要： An article of manufacture forms a tool for determining cleaning parameters of an oxide removal process. The article comprises a block of material upon which an oxide can be formed and a simulated defect structure disposed in the block of material. The article is capable of determining oxide removal parameters of an oxide removal process by disposing an oxidized standard in a reactor, conducting an oxide removal process to remove oxide from the standard, and evaluating the standard and simulated defect structure for remaining oxide and other oxide removal parameters.

摘要： A method for the recycling of overspray powder during spray forming is provided. The method involves providing a refining vessel to contain an electroslag refining layer floating on a layer of molten refined metal. An ingot of unrefined metal is lowered into the vessel into contact with the molten electroslag layer. A current is passed through the slag layer to the ingot to cause surface melting at the interface between the ingot and the electroslag layer. As the ingot is surface melted at its point of contact with the slag, droplets of the unrefined metal are formed and these droplets pass down through the slag and are collected in a body of molten refined metal beneath the slag. The refined metal is held within a cold hearth. At the bottom of the cold hearth, a cold finger orifice permits the withdrawal of refined metal from the cold hearth apparatus. The refined metal passes from the cold finger orifice as a stream. The stream is atomized for spray forming into a preform article on a spray collection station having a solid receiving surface for receiving the atomized metal thereon to form the preform article. The powder produced during the atomization which was not deposited on the solid receiving surface of the spray collection station is recycled onto the top of the molten slag in the electroslag refining station.

摘要： A system for controlling the flow rate of the stream from an electroslag refining apparatus is taught. The system includes the introduction of unrefined metal into an electroslag refining process in which the unrefined metal is first melted at the upper surface of the refining slag. The molten metal is refined as it passes through the molten slag. The refined metal is collected in a cold hearth apparatus having a skull of refined metal formed on the surface of the cold hearth for protecting the cold hearth from the leaching action of the refined molten metal. A cold finger bottom pour spout is formed at the bottom of the cold hearth to permit dispensing of molten refined metal from the cold hearth. The flow rate of molten metal through the cold finger apparatus is controlled by coordinating, among other parameters: the rate of melting of the unrefined metal; the hydrostatic head of molten metal and slag above the bottom pour cold finger orifice; the rate of induction heat supplied to the metal within the cold finger apparatus; the rate of heat removal from the metal within the cold finger apparatus through the cold finger apparatus itself and through adjacent gas cooling means; and by applying electromagnetic force to selectively speed up, slow down and/or interrupt the flow of metal through the cold finger apparatus via an electromagnetic orifice, preferably utilizing a processor, such as a computer.

摘要： A method for forming an exterior surface of a high-temperature component, such as a blade or vane of a gas turbine engine. The method entails forming a shell by a powder metallurgy technique that yields an airfoil whose composition can be readily tailored for the particular service conditions of the component. The method generally entails providing a pair of inner and outer mold members that form a cavity therebetween. One or more powders and any desired reinforcement material are then placed in the cavity and then consolidated at an elevated temperature and pressure in a non-oxidizing atmosphere. Thereafter, at least the outer mold member is removed to expose the consolidated powder structure. By appropriately shaping the mold members to tailor the shape of the cavity, the consolidated powder structure has the desired shape for the exterior shell of a component, such that subsequent processing of the component does not require substantially altering the configuration of the exterior shell. The airfoil can be produced as a free-standing article or produced directly on a mandrel that subsequently forms the interior structure of the component. In one embodiment, an airfoil is configured to have double walls through which cooling air flows.

摘要： A method of repairing cracks, imperfections, and the like in a cast article. A frusto-conical aperture is created in the article in the location of the crack or imperfection. A mating tapered plug is prepared such that the tapered plug can fit into the aperture so that the sloped side walls of the tapered plug evenly and unilaterally rest on frusto-conical sides of the aperture. The tapered plug is disposed into the aperture, and bonding material is applied between the surfaces of the tapered plug and the aperture, before or after insertion of the tapered plug into the aperture. The article is thereafter heated such that the bonding material joins the surfaces of the tapered plug and the aperture. The outer end of the tapered plug thereafter is polished so that such outer end is approximately level with the article's outer side in a refinement of the invention, the plug member may be pushed into the aperture such that a controlled interference fit is produced.

摘要： A method of forming an internal channel within an article, such as a cooling channel in an air-cooled blade, vane, shroud, combustor or duct of a gas turbine engine. The method generally entails forming a substrate to have a groove recessed in its surface. A sacrificial material is then deposited in the groove to form a filler that can be preferentially removed from the groove. A permanent layer is then deposited on the surface of the substrate and over the filler, after which the filler is removed from the groove to yield the desired channel in the substrate beneath the permanent layer.
