Embodiment Construction

[0043] figure 1 Schematically shown for the manufacture of workpieces or components (see figure 2 Reference numeral 100 in ), for example a sequence of a method for a component of a fluid machine, such as a gas turbine. The workpiece 100 is preferably a high temperature resistant workpiece for use in connection with the hot air path of a gas turbine. The workpiece or component preferably consists of a nickel-based or cobalt-based superalloy or contains corresponding materials.

[0044] The method includes: providing a substrate 1, the substrate is in figure 1 or figure 2 Shown in side view or cross-sectional view. The substrate 1 comprises a predetermined surface structure 2 . The predetermined surface structure 2 is preferably a surface structure with surface structure units 10, as in figure 1 and 2 as indicated in. The surface structure units 10 each have a rectangular cross section. The surface structure units 10 are preferably microscopically small. In other wo...

Abstract

The invention relates to a method for producing a work piece (100). The method comprises the providing of a substrate (1) having a predetermined surface structure (2) and the generative manufacturingof a material (5) for the work piece (100) on the surface structure (2), such that the surface structure (2) defines a base surface (3) of the work piece (100) to be manufactured, wherein the generative manufacturing is carried out by means of deposition welding and wherein the base surface (3) is an at least partially interior surface of the work piece (100) in respect of a contour (4) of the work piece (100) that is to be manufactured. The method furthermore comprises the detaching of the substrate (1).

Description

technical field [0001] The invention relates to a method for producing workpieces, for example high-temperature-resistant workpieces, such as workpieces or components used in the hot gas path of fluid machines, for example gas turbines. Furthermore, the invention relates to a workpiece which is produced or can be produced by means of the method. Background technique [0002] Additive or generative manufacturing methods ("rapid prototyping" in English, rapid prototyping) for the manufacture of three-dimensional (3D) structures, such as e.g. selective laser melting (SLM, "selective lasermelting" in English) and overlay welding, e.g. laser Overlay welding ("laser cladding" in English, or LMD for "laser metaldeposition") is used, for example, in the manufacture and repair of parts of gas turbines that are loaded with hot gas or subjected to high temperature loads. SLM methods allow the generative construction of complex shaped bodies or workpieces with relatively fine internal ...
