  • Patent number: 10478921
    Abstract: A method for generating, in layers, an application structure made of high heat resistant super alloys on a substrate is provided. A powdery construction material is melted by an energy beam at a working point, wherein the working point is guided across the substrate along a primary movement direction and thus swings transversely to the primary movement direction. The working point thereby swings from a first edge of a respective layer of the application structure to a second edge of the layer. In this way, a time interval passes between departure from a respective edge and a return to the respective edge directly following the departure, such that a melt bath on the respective edge solidifies into a paste-like zone during the time interval.

  • Publication number: 20190211684
    Abstract: A method for the additive manufacturing of a component includes: the additive building up of a structure from a base material for the component by an additive manufacturing method; the introduction, during the additive building up of the structure, of a porous auxiliary structure into an interior of the structure to define a functional area for the component in the interior; and the removing, in particular melting, of the porous auxiliary structure from the functional area by heating the auxiliary structure so that the functional area no longer has the auxiliary structure. A component is produced in accordance with the method and a corresponding device.

  • Patent number: 10286490
    Abstract: A method is provided for welding a substrate, in which an energy source and/or a material feed is or are moved in an oscillating motion over the surface of the substrate. The oscillating movement in a vertical and/or horizontal direction during welding results in smaller grains, which prevent the formation of fractures during welding.

  • Patent number: 10100651
    Abstract: A coated high-temperature component including a cobalt coating that has a higher carbon content is provided. A layer composed of a cobalt-based alloy is applied which is known as or is similar to substrate material, to the region of the component which is subject to the wear, wherein the component preferably comprises a nickel-based alloy as substrate material, the carbon content of which is lower than that of the cobalt-based alloy. At the high operating temperatures, carbon diffuses from the coating into the base material; this is normally undesirable, but here leads to a higher carbide proportion in the substrate and therefore to a higher hardness and therefore to an increased wear resistance.
