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.

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.

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.

The invention relates to a method for producing a layer () having nanoparticles (), on a substrate (). The invention is based on the object of specifying a method for producing a layer containing nanoparticles, which method can be carried out particularly easily and nevertheless offers a very wide degree of freedom for the configuration and the composition of the layer to be produced. According to the invention, this object is achieved in that nanoparticles () are released and a nanoparticle stream () is produced in a first process chamber (), the nanoparticle stream () is passed into a second process chamber (), and the nanoparticles () are deposited on the substrate () in the second process chamber ().

Short fibers in a solder or a welding material often do not have the desired strength. The invention uses fiber mats () which have been introduced onto a surface () or into a recess () of a metallic component.

The invention relates to a material composition that is used for producing a coating for a component, especially a turbine component, which is made of a metallic basic material, i.e. a metal or a metal alloy. Said material composition comprises a matrix material for forming a basic coating matrix and at least one filler for adjusting desired coating proportions or coating characteristics. The matrix material can be provided especially with basic glass ceramic properties. The inventive material composition is characterized in that the matrix material and/or the filler contains nanoparticles.
