    摘要： A method is provided for joining a filler material to a substrate material. The method includes melting the filler material within a melting chamber of a crucible such that the filler material is molten. The crucible has an outlet fluidly connected to the melting chamber. The method also includes holding the filler material within the melting chamber of the crucible by applying a first pressure differential across the outlet of the crucible, and releasing the filler material from the melting chamber of the crucible by applying a second pressure differential across the outlet of the crucible to deliver the filler material to a target site of the substrate material. The second pressure differential has a different value than the first pressure differential.

    摘要： Methods are provided for repairing a worn surface of a steel die-cast die. The method includes heating an amorphous material to a predetermined temperature with a laser beam and allowing the melted amorphous material to solidify to thereby form an amorphous layer over the worn surface. These processes are useful for eliminating or minimizing cracking and/or part distortion and minimize heat-affected zone during welding. In addition, the formation of an amorphous layer over the worn surface allows the repaired die-cast die to better withstand typical operating environments than previous repair materials. These methods combine low heat input welding with amorphous alloys to effectively repair die-cast dies.

    摘要： A method for repairing a blade tip of a turbine blade of a gas turbine engine. The method is particularly directed to replacing the squealer tip (14) of a directionally solidified (DS) or single crystal (SX) turbine blade (10), and can be carried out using a brazing or welding technique. The method generally entails the step of machining the tip (14) to remove any damaged, worn, oxidized or eroded portions thereof sustained by the blade (10) during engine operation. A DS or SX superalloy replacement tip (18) is then placed on the surface generated by the machining operation. If a brazing operation is used, a brazing alloy composition (16) is first applied to the blade tip or replacement tip (18) prior to placement of the replacement tip (18). The brazing alloy composition (16) is composed of at least two alloys, one of which having a melting point lower than the recrystallization temperature and solvus temperature of the superalloy of the turbine blade (10), such that heating causes the brazing alloy composition (16) to flow and thereby join the replacement tip (18) to the blade tip of the turbine blade (10). Alternatively, if a welding operation is employed, the joining operation entails transmitting current through the turbine blade (10) and replacement tip (18) to resistance weld the replacement tip (18) to the blade tip of the blade (10).

    摘要： An extension is formed directly on an article by dipping a portion or end of the article having an attached integral mandrel into a molten bath of a compatible alloy, followed by withdrawal of the end under controlled conditions sufficient to cause an integral extension to solidify on the article. A ceramic mold is utilized over the dipped end of the article and the integral mandrel with a mold cavity that generally defines the shape of the extension to be formed. The mold may be formed in situ on the mandrel, or preformed and attached to the subject article over the mandrel. The integral mandrel is melted within the mold by dipping the mandrel into the molten alloy. The mandrel acts as a buffer between the molten material and the article while permitting melting of the article end and solidification of the integral extension. Extensions formed by the method of this invention have a microstructure that is continuous and compatible with that of the article. Such microstructures may include epitaxial growth of the extension from the microstructure of the article. The method establishes a temperature gradient within the article during solidification that may be further controlled by auxiliary heating and/or cooling of the article and/or extension during the practice of the method.
