  • Method, device and powder for the additive manufacturing of a component with oxide dispersion strengthening and corresponding component
    Patent number: 11654485
    Abstract: A method for the additive manufacturing of a component includes providing a powdered base material for a component, in particular a component for the hot gas path of a gas turbine, building up the component layer by layer on a building platform by fusing individual layers of the base material, and introducing an oxide dispersion strengthening into a region of the component to be additively manufactured by an oxidic additive, wherein the region is usually exposed to high thermomechanical loading during operation of the component.
    Type: Grant
    Filed: April 17, 2019
    Date of Patent: May 23, 2023

  • Continuous flow machine having multiple guide vane stages and method for partially disassembling a continuous flow machine of this type
    Patent number: 10844747
    Abstract: A continuous flow machine has at least one annular guide vane carrier. The guide vane carrier, formed at least by a lower part and an upper part detachably connected to same, has at least three guide vane stages retained on the inner circumference of the at least one guide vane carrier, arranged axially behind one another in the flow direction and each having a plurality of radially extending guide vanes. Each of the guide vanes also has a guide vane blade, a base plate and a top plate, wherein the guide vane blade extends between the base plate and top plate. Via the arrangement of the securing pin in an intermediate space accessible in the assembled state, a partial disassembly of the individual guide vane stages is possible, independent of the remaining guide vane stages. The guide vane stages are conventionally mounted via retaining protrusions on neighbouring guide vane stages.
