The present disclosure relates to powder-bed-based additive manufacturing processes. Embodiments thereof may include methods for producing a component from a superalloy. For example, a method for producing a component comprising a superalloy may include: preheating a powder bed comprising particles of a core material coated by a ceramic layer, the core material including alloying constituents of the superalloy and building up the component layer by layer in a powder bed by melting particles with an energy beam. The powder bed may be heated to a temperature below a melting point of the core material before the particles are melted.

Powder-bed-based additive manufacturing process

A magnetic steel sheet including a layer adjoining at least one of a top side and bottom side of the magnetic metal sheet. The layer includes a metal oxide containing titanium oxide or tantalum oxide and the layer adjoins the magnetic steel sheet along a diffusion zone into which the titanium or tantalum of the metal oxide has diffused into the magnetic steel sheet. The diffusion zone is produced on at least one of a top surface and a bottom surface of the magnetic steel sheet and the diffusion layer diffuses one of tantalum and titanium as metal into the at least one surface. The metal of the at the at least one surface is converted into an associated metal oxide to form the layer including the metal oxide, and a residual content of the metal of the metal oxide remains in the diffusion zone.

A method prepares a repair material for and repairs a damage point in the surface of cast parts. Spray particles having the same cast structure as the cast part are used as materials. The particles are applied to the damage point by cold gas spraying. The cold gas spraying is performed such that the spray particles are not melted and, advantageously, the cast structure is retained after the spray particles contact the repair point. The repair point can thus be advantageously furnished with the same properties as the rest of the component to be repaired. The repair material can be produced in that a cast part having the required cast structure is reduced to small pieces.

Method for repairing a damage point in a cast part and method for producing a suitable repair material

A method for producing a cast metal piece and a cast metal piece are provided. An information element includes at least one piece of information. The information element is produced from a magnetizable material and the information is deposited n the magnetizable material and is cast into the information element during casting of the price, the casting temperature being above the Curie temperature of the magnetizable material of the information element.

In a method for producing a starting material (M, N, N') for the production of a wear layer (), a coating () with a composition which corresponds to that of the wear layer () which is to be produced is chemically undissolved from its substrate () and is detached as a solid body, and that the starting material (M, N, N&#x2032;) is formed by the layer material () of the detached coating ().

Method for producing a wear layer

In a method for depositing a non-metallic, in particular ceramic, coating on a substrate () by cold gas spraying, the method has the steps of: producing a reactive gas flow () having at least one reactive gas, injecting into the reactive gas flow () particles () consisting of at least one material required for producing a non-metallic, in particular ceramic, coating material by reaction with the reactive gas, so as to form a mixture flow of reactive gas and particles (), producing reactive gas radicals in the mixture flow, and directing the mixture flow having reactive gas radicals and particles onto a surface of a substrate () to be coated, and so a non-metallic, in particular ceramic, coating is deposited on the surface of the substrate (). In addition, a description is given of a device () for carrying out the method.

Method and device for depositing a non-metallic coating by means of cold-gas spraying

In a method for producing a component () with a coating () containing nanoparticles (), it is provided that, in order to introduce the nanoparticles () into the coating (), a film () with the dispersely distributed nanoparticles () is applied to the surface () to be coated, which decomposes with incorporation of the nanoparticles () during the actual coating operation and is thereby not incorporated into the layer.

Method for producing a component with a nanostructured coating

The turbine parts, when they are used, form oxide layers which by the undesirable rapid growth thereof generate the damage of the parts substrate. The inventive method consists in depleting the part in an element in such a way that the oxide layer is reduced.

Process for producing a component of a turbine, and a component of a turbine

There is described a substrate with a coating; the coating contains a coating matrix in whose matrix structure multilayered and/or encapsulated nanoparticles are arranged and release a dye when a limit temperature is exceeded the first time and/or trigger a color reaction which causes the color of the coating to change irreversibly.

Substrate with applied coating and production method

A method for repairing a component such as a turbine blade is provided. At the end of its operating time, the component has, for example, a depletion of aluminium in a region near the surface. The application of a repair layer is provided including particles with an increased proportion of aluminium. A subsequent heat treatment may achieve the effect of equalizing the concentration of aluminium between the repair layer and the region near the surface, and so the aluminium content required for new components is achieved again.

Method for repairing a component by coating

The invention relates to a component for arrangement in the duct of a turbine engine. The component is provided with a coating, which has a surface structure with scales which overlap each other in the direction of flow of the turbine engine. The invention also relates to a spraying method for generating a coating on a component.

In a method particles in a thermal spraying process are entrained by a carrier gas stream and deposited on a component to be coated. The particles are dispersed in a liquid or solid additive before being introduced into a supply line which issues into the thermal spraying apparatus, the additive, after leaving the supply line, being transferred into the gaseous state in the carrier gas stream. A liquid additive evaporates or a solid additive is sublimated, whereby the particles in the carrier gas stream are separated. The dispersal of the particles in the additive simplifies an exact metering and prevents the particles from forming lumps, so that improved layers can be deposited by virtue of an improved homogeneity of the carrier gas stream. As the additive has been transferred into the gaseous state, it is not deposited in the layer.

Method for feeding particles of a coating material into a thermal spraying process

A powder can be produced by immersing microparticles () in a first solution () which contains coupling molecules (), and then in a second solution () which contains the nanoparticles (), thereby producing microparticles () with nanoparticles () attached thereto. The particles form powder particles () which allow nanoparticles () that are smaller than approximately 5 [mu] to be applied to a component by cold gas spraying.

Powder for cold spraying processes

The invention relates to a cold gas spraying method with the aid of which a substrate to be coated can be coated with particles. According to the invention, it is provided that microencapsulated agglomerates of nanoparticles are used as particles. This advantageously allows the advantages that accompany the use of nanoparticles to be used for the coating. The nanoparticles are held together by microencapsulations, wherein the microencapsulated particles formed in this way that are used in the cold gas spraying method have dimensions in the micrometer range, thereby allowing them to be used in the first place in cold gas spraying The microencapsulated nanoparticles may be used for example to produce a UV protective coating on lamp bases for gas discharge lamps.

Cold gas spraying method

Short fibers in a solder or a welding material often do not have the desired strength. Fiber mats that are introduced onto a surface or into a recess of a metallic component are provided. In addition a process for applying material to a metallic component is provided. In the process, a first fiber mat and a second fiber mat are used.
