摘要:
The invention relates to a method of, and a nozzle arrangement for, spraying cold gas. The nozzle arrangement has a first nozzle and a second nozzle, which is arranged within the first nozzle. The first nozzle is fed a gas which optionally contains particles. The second nozzle is fed a particle-containing gas. The particles are applied to a surface of the substrate by means of the gases.

A method is disclosed for producing a chemoactive useful layer and sensor is disclosed, including a chemoactive useful layer. In at least one embodiment, a method is disclosed for producing a chemoactive useful layer. In at least one embodiment, nanoparticles having a catalytic action are introduced into the useful layer.
摘要:
The cold spraying process according to the invention uses cold gas streams whose properties (temperature (T), particle density (p), pressure (p), particle velocity (v)) are variably changed such that they can be adapted to the desired properties of the coatings.
摘要:
Inner coatings according to the prior art often do not produce a uniform coating. The method according to the invention for the coating of a component with a cavity is characterized in that a coating material is mixed with a carrier material and introduced into the cavity, the carrier material decomposing at the evaporating temperature of the coating material, or has already decomposed, and the coating material being deposited from the gas phase on the component.
摘要:
The invention relates to a process for cleaning passages in workpieces, in particular cooling-air passages in turbine components, such as transition pieces or turbine blades or vanes, wherein the workpiece having the passages is immersed in a liquid bath and a liquid is suddenly forced under pressure through the passages.
摘要:
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.
摘要:
In a method for producing a starting material (M, N, N′) for the production of a wear layer (420), a coating (40) with a composition which corresponds to that of the wear layer (420) which is to be produced is chemically undissolved from its substrate (30) and is detached as a solid body, and that the starting material (M, N, N′) is formed by the layer material (60) of the detached coating (40).
摘要:
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.
摘要:
The cold spraying process according to the invention uses cold gas streams whose properties (temperature (T), particle density (ρ), pressure (p), particle velocity (v)) are variably changed such that they can be adapted to the desired properties of the coatings.
摘要:
A powder can be produced by immersing microparticles (2) in a first solution (4) which contains coupling molecules (5), and then in a second solution (10) which contains the nanoparticles (12), thereby producing microparticles (2) with nanoparticles (12) attached thereto. The particles form powder particles (14) which allow nanoparticles (12) that are smaller than approximately 5 [mu] to be applied to a component by cold gas spraying.
