摘要:
In prior art, electrolytic methods are used for processing large exterior surfaces. According to the inventive method, through holes (7, 7', 7'', 7''', 7'''', 7''''') of a wall (4) are treated on the inside, one respective pole electrode (19, 19', 19'', 19''') being assigned to each through hole (7, 7', 7'', 7''') that is to be processed.

The invention relates to a method of, and a nozzle arrangement for, spraying cold gas. The nozzle arrangement has a first nozzle (1, 3, 5) and a second nozzle (2, 4, 6), which is arranged within the first nozzle (1, 3, 5). The first nozzle (1, 3, 5) is fed a gas which optionally contains particles. The second nozzle (2, 4, 6) is fed a particle-containing gas. The particles are applied to a surface of the substrate by means of the gases.

The invention relates to a method for producing a layer (110), which has nanoparticles (40), on a substrate (100). The aim of the invention is to provide a method for producing a layer containing nanoparticles, which can be carried out particularly easily while still offering a high amount of flexibility in the design and the composition of the layer to be produced. To this end, the invention provides that, in a first process chamber (10), nanoparticles (40) are released and a nanoparticle flow (50) is generated. The nanoparticle flow (50) is directed into a second process chamber (80), and the nanoparticles (40) are deposited onto the substrate (100) in the second process chamber (80).

The invention relates to a method for determining the wall thickness of a hollow component (1). According to said method, a temporally variable magnetic field is used to induce a secondary magnetic field in a component wall (5) surrounding a cavity (3) of the component (1). The thickness of the component wall (5) is determined by detecting at least one variable of the component wall (5) influencing the secondary magnetic field. Before the at least one variable is detected, a ferromagnetic material (11) is applied to the side (6) of the component wall (5) facing the cavity (3) or introduced into the cavity (3). The ferromagnetic material is added by means of a volatile solvent in which it is ionically dissolved or suspended with a binder as a ferromagnetic powder. The at least one variable is detected following the evaporation of the solvent.
