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.

A seal segment for a turbine and an assembly for sealing the gaps between seal segments and stator vanes of a turbine. The seal segments have a plate-shaped wall, the first lateral surface of which faces the vane tips in the assembled state of the seal segments, is surrounded by a closed circumferential edge, and can be divided into four lateral wall sections, and the plate-shaped wall has a seal element which is arranged over the entire surface of the lateral surface. A number of seal lamellae which are secured on one side are provided on at least one of the lateral wall sections and/or on at least one of the seal lateral wall sections facing adjacent seal segments when the seal segments are assembled in a turbine so as to form a ring in order to reduce a flow along the corresponding lateral wall section.

A method of processing a surface in additive manufacturing includes assembling a structure for a component by additive manufacturing out of a bed of a powdery base material, such that the structure is provided with an internal surface and a powdery base material covers at least a part of the internal surface, and actuating the base material relatively to the structure such that the internal surface is mechanically processed by the base material.
