The use of different ceramic layers allows different configurations of gas turbines to be produced each of which is optimized for a respective use of base load operation or peak load operation.

Method for treating a gas turbine blade and gas turbine having said blade

Through the use of different ceramic heat insulation coatings () on turbine blades, it is possible to produce or restore different configurations of gas turbines, which are then optimized for a respective baseload operation application or peak load operation application. Differences in the sprayed-on heat insulation coatings () can be generated by means of a different material composition of the powder, for example zirconium oxide, by means of a different number of layers (), by means of different coating thicknesses and/or by means of different porosities.

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

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 ().
