The invention relates to a method and device for generatively producing components, said device comprising a radiation device for selectively radiating a powder bed, and an induction device for inductively heating the component produced by radiating the powder bed, Said induction device comprising at least one voltage source which can simultaneously produce alternating voltages with at least two different frequencies.

Multi-frequency induction heating of generatively produced components

Disclosed is a method for monitoring a generative fabrication process in which a component is formed in an installation space from a multiplicity of layers by using a three-dimensional data model and a following layer is fixed to a preceding layer by means of a high-energy beam. The method comprises detecting the component at least optically and detecting the installation space thermally during layer application. Also disclosed is a device for carrying out the method.

Method and device for process monitoring

The invention relates to a generative production method for producing a component by selectively melting and/or sintering a powder several times consecutively by introducing an amount of heat by means of beam energy, such that the powder particles melt and/or sinter in layers, wherein the powder particles () are made of a first material () and the powder particles are surrounded by a second material () partially or over the entire surface thereof, wherein the second material has a lower melting point than the first material and/or lowers the melting point of the first material when mixed with the first material. The invention further relates to a corresponding powder and to a prototype produced from said powder.

Generative production method and powder therefor

A method for producing a component is disclosed. The method includes calculating a load line of the component as a result of a load to be absorbed by the component and applying a layer on a core by gas dynamic cold spraying, where the layer has a layer section and where the layer section runs along the calculated load line.

A rotor for a turbo engine is disclosed including a rotor base body and a plurality of rotor blades distributed over the circumference of the rotor base body. The rotor base body is formed by at least one ring-shaped element made of a metal matrix composite material. The rotor blades are attached by footing to the rotor base body in such a way that the footing is positioned in a fiber-free area of the rotor base body.

A semifinished product of composite material consists of a metallic matrix material and high tensile strength fibers embedded in the matrix material, whereby the metallic matrix material is formed of titanium or a titanium based alloy. Ceramic particles are encased or embedded in the matrix material for increasing the strength of the semifinished product with respect to torsional loading or transverse loading. The product is produced by a method in which the fibers are coated with the matrix material, ceramic particles are embedded in the matrix material coating the fibers, and then the thusly coated fibers are arranged in a desired geometry and are consolidated to form the product.

A process for is producing a fiber-reinforced semifinished product in the form of metal strips, metal sheets etc., from at least one layer of fibers which includes a number of long to endless reinforcing fibers spaced apart from one another and arranged in parallel and a metal. A metal jacket applied to the reinforcing fiber by a PVD process (physical vapor deposition) may act for example as the metal. At least certain regions of the metal and the reinforcing fibers run through a welding process in which a bonding takes place by planar melting of the metal to form a matrix surrounding the reinforcing fibers.

A wear-resistant layer is applied to a surface, which is to be protected, of a component which is subjected to mechanical and/or fluidic loads and substantially consists of amorphous or amorphous-nanocrystalline metals. The layer for protecting against abrasive or erosive wear substantially consists of an Ni&mdash;W-base alloy or substantially consists of an alloy based on Cu&mdash;Al&mdash;Ti(or &mdash;Ta or &mdash;Zr) or Pd&mdash;Cu&mdash;Si or Pt&mdash;Al&mdash;Si or Ta&mdash;Si&mdash;N, or substantially consists of an alloy of Al, at least one rare earth and a transition metal, such as Cu or Ni or Co.

Antiabrasion coating

A method of producing fiber-reinforced metallic building components having a complicated three-dimensional geometric shape includes the following steps. First, metal-coated SiC fibers are applied to a metallic sectional piece having a simple geometric shape, and are then held thereon without restraint by a metallic counterpart piece. Then, the unit consisting of the sectional piece, fibers and counterpart piece undergoes plastic deformation in vacuo between mold halves by applying pressure at an elevated temperature, without bonding of the fibers to one another or to the building component metal. By further increasing the pressure and/or temperature, the molded unit is compressed further between the mold halves and is consolidated to a monolithic part by metallic bonding (diffusion welding), whereby the part, either alone or bonded to other parts, forms the building component, after cooling and removing it from the mold halves.
