摘要： Methods for laser additive manufacture are disclosed in which a plurality of powder layers (48, 50 and 52) are delivered onto a working surface (54A) to form a multi-powder deposit containing at least two adjacent powders layers in contact, and then applying a first laser energy (74) to a first powder layer (48) and a second laser energy (76) to a second powder layer (52) to form a section plane of a multi-material component. The multi-powder deposit may include a flux composition that provides at least one protective feature. The shapes, intensities and trajectories of the first and second laser energies may be independently controlled such that their widths are less than or equal to widths of the first and second powder layers, their intensities are tailored to the compositions of the powder layers, and their scan paths define the final shape of the multi-material component.

摘要： The present invention relates to flux compositions and methods for laser processing volatile alloys. A flux composition contains a metal oxide, a metal silicate, or both; a shielding agent which forms at least one gas upon heating; and a plasma-generating agent, but not a metal fluoride. A process involves applying an energy beam (10) to a flux composition (6) such that the flux composition reacts to form a plasma (14) and a shielding gas (18). An amount of energy applied to the flux composition is controlled to convert the flux composition into a molten slag blanket (16) in the presence of the shielding gas without completely melting an alloy material (4) situated below the flux composition. The molten slag blanket then heats the alloy material by thermal conduction in the presence of the shielding gas to form a pressurized melt pool (22) of the alloy material, which cool and solidifies.

摘要： An additive manufacturing apparatus and process for selectively heating a fluidized bed of powdered material (14), including powdered metal material (14') and powdered flux material (14')' with an energy beam (20). The powdered material is held within a chamber (12) to repair or manufacture a component (22). The powdered bed is fluidized by introduction of a non-inert gas into the chamber. Relative movement between the energy beam and component is controlled in accordance with a predetermined shape of the component. As the powdered material is heated, melted and solidified, a layer of slag (32) forms over a deposited metal (38) and is then removed so that fluidized powdered metal settling on a previously deposited metal substrate (34) can be heated, melted and solidified to build up the component.

摘要： Laser cladding filler material is introduced in a pattern on a on a substrate by a filler distribution apparatus having a linear or polygonal array of dispensing apertures for uniform distribution in advance of or during a laser beam transferring optical energy to the substrate. The distribution apparatus includes a housing (or assembly of coupled housings) that defines the distribution aperture array and an internal chamber in communication with the apertures that is adapted for retention of filler material. A mechanical feed mechanism, such as an auger, is adapted for feeding filler material from the internal chamber through the distribution apertures. A feed mechanism drive system is coupled to the mechanical feed mechanism, adapted for selectively varying filler material feed rate. The distribution aperture array may be selectively reconfigured to vary selectively the filler material distribution pattern.

摘要： Superalloy components are joined or repaired by mating a recess formed in one component substrate with a corresponding projection formed in another component along a contact surface and welding them together with a stud welding apparatus. A mating superalloy repair stud is formed with a stud projection whose profile conforms to the substrate recess profile along a corresponding contact surface. Both the stud and substrate are coupled to a stud welding apparatus, with the stud projection and substrate recess oriented in an opposed spaced relationship with a gap there between. The stud welding apparatus passes current between the stud projection and recess and forms an arc there between, to melt their respective opposed surfaces. The melted stud projection and substrate recess opposed surfaces are pressed into contact with each other with the stud welding apparatus, forming a weld there between.

摘要： Superalloy components are joined by mating a recess (44) formed in one component (40) with a corresponding projection (52) formed in another component (50) along a contact surface. The components are compressed along the contact surface and resistance heat welded to each other. Current is passed between the components at a selected flow rate and application time until localized melting occurs along the contact surface, and they are mutually affixed to each other. When repairing a damaged surface portion of a superalloy material component, the damaged portion is removed to form an excavated recess. A repair splice is formed, preferably of a same material with similar mechanical structural properties, having a mating projection with profile conforming to the corresponding recess profile. The splice and substrate are resistance heat welded under compression pressure until localized melting occurs along the contact surface, so that they are mutually affixed.

摘要： An electrode (10) is presented including a sheath (14) formed of a ductile material, an outer coating (16) including a flux material, and a core (12) including at least one of flux material and alloying material. The ductile material may be an extrudable subset of elements of a desired superalloy material and the alloying material may include elements that complement the ductile material to form a desired superalloy material when the electrode is melted. The outer coating may be formed of a flexible bonding material or it may be segmented (18, 20) to facilitate bending the electrode onto a spool. Any hygroscopic material of the electrode may be included in the core to protect it from exposure to atmospheric moisture.
