Method for ascertaining a concentration of at least one material in a powder for an additive production method

A method for manufacturing at least a metallic portion of a component: a) depositing metallic material layer by layer onto at least one building platform; b) locally fusing and/or sintering the material layer by layer by supplying energy by at least one high-energy beam in the region of a buildup and joining zone to form at least a portion of at least one component layer of the component portion and/or of the component; c) lowering the building platform layer by layer by a predefined layer thickness; and d) repeating the steps a) through c) until completion of the component portion and/or of the component. Before, during and/or after process step b), at least one further portion of the component layer is formed by locally fusing and/or sintering the material by inductive heating at a temperature or in a temperature range above the solidus temperature of the metallic material used. A system for manufacturing at least a portion of a component is also provided.

The invention relates to a method for the additive manufacture of at least one region of a component. Here, at least the following steps are carried out: a) layer-wise application of at least one powder-form component material onto a component platform in the region of a build-up and joining zone; b) layer-wise and local solidifying of the component material by selective exposure of the component material by at least one high-energy beam in the region of the build-up and joining zone, with the formation of a component layer; c) layer- wise lowering of the component platform by a pre-defined layer thickness; and d) repeating steps a) to c) until the component region or the component has been completely fabricated.

A seal segment assembly for a turbomachine, in particular a gas turbine, including a first seal carrier and a second seal carrier, that are adjacently disposed in the circumferential direction, the first seal carrier having a first carrier base and at least one first sealing member that is joined to the first carrier base, and the second seal carrier having a second carrier base and at least one second sealing member that is joined to the second carrier base, the first sealing member and the second sealing member being formed by a plurality of cavities, that are adjacently disposed in the circumferential direction and in the axial direction, in particular evenly spaced, the cavities extending in the radial direction from the particular carrier base. The first carrier base and the second carrier base are intercouplable or are intercoupled in the circumferential direction by a mating connection assembly.

Repair method for the additive repair of a component

The invention relates to a method for the quality assessment of a component produced by means of an additive manufacturing method. In the course of the method, it is checked first of all whether the component violates predetermined absolute limits in order to rule out the existence of serious malfunctions in the additive manufacturing process. Subsequently, a component-dependent targeting process is determined. On the basis of this targeting process, the limits for deviations are established and deviating actual values of the component are isolated and assessed by means of various parameters.

An apparatus and method for the generative production of a component includes a movably dispensing structure for the disposal of a starting material layer; a bonding device, such as a laser, for the local bonding of this starting material layer to a cross section of the component being produced; a platform for supporting the component being produced, which can be displaced counter to a direction of layer buildup in a motor-driven manner; a position sensing device for sensing a position or change in position, such as vibration, of the platform in the direction of layer buildup with the capability of sensing interference as to whether the movement of the dispensing structure is not free of interference on the basis of the sensed position or change in position.
