Abstract:
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.
Abstract:
A method for coating a plastic surface and a plastic component is disclosed. The method includes applying a base layer to a plastic surface. A layer of a coating is applied by kinetic cold gas spraying on the base layer. The base layer is applied by a method that is different from the kinetic cold gas spraying. The base layer adheres to the plastic surface and the layer of the coating applied by kinetic cold gas spraying is deposited on the base layer by the kinetic cold gas spraying.
Abstract:
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.
Abstract:
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.
Abstract:
The invention relates to a component, which has a layer applied by gas dynamic cold spray, said layer having at, least one layer section or a reinforcing element, the material and orientation of which are selected according to a load line, and to a method for producing such a component by gas dynamic cold spray.
Abstract:
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.
Abstract:
Disclosed is a method for monitoring a generative production process in real time, wherein a component is at least optically detected and the installation space is thermally detected when applying a layer, as well as a device for carrying out said method.
Abstract:
The present invention relates to a method for producing gas turbine components, in particular aircraft turbine components, preferably low-pressure turbine blades, from a powder which is sintered selectively in layers by locally limited introduction of radiant energy, wherein the sintering is carried out in a closed first housing (2), so that a defined atmosphere can be set, wherein the powder or at least a part of the powder is generated in the same first housing (2) or in a second housing connected to the first housing in a gas-tight manner. The invention further relates to a corresponding apparatus and to a gas turbine blade produced thereby.

Abstract:
The invention relates to a method for producing a semifinished product from a composite material. The semifinished product is made of a composite material consisting of a metallic matrix material and of high-tensile fibers embedded in the matrix material, whereby the metallic matrix material is formed from titanium or from a titanium-based alloy. According to the invention, ceramic particles are incorporated in the matrix material in order to increase the strength of the semifinished product with regard to torsional stress or transversal stress.
