Various embodiments include a device for the selective electrochemical machining of workpieces comprising: a machining head equipped with an electrolyte transmitter; and a supply channel for an electrolyte. The electrolyte transmitter is arranged in an interior of the supply channel and protrudes through an outlet opening of the supply channel to form a machining surface for the workpiece. The electrolyte transmitter comprises a cylinder arranged movably in the supply channel axially displaceable in the outlet opening.

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.

Various embodiments include a method for producing a structure with a cold gas spraying method comprising: providing a carrier with a carrier surface, to which the structure is to be attached by the cold gas spraying method by following a travel path; and providing an element with an element surface different from the carrier surface. The element is arranged in the travel path and/or the travel path is specified such that intersections of the travel path and/or interruptions of the structure are arranged on the element surface.

Various embodiments of the teachings herein include a method for coating a membrane with a catalyst. An example method includes: positioning a membrane in a reactor chamber; coating the membrane on a first surface with a metal by atomic layer deposition; purging the reactor chamber to remove any metal remaining in the reactor chamber and not deposited on the at least one surface of the membrane; generating a plasma using a plasma source within the reactor chamber and contacting the plasma with the metal deposited on the first surface of the membrane; and purging the reactor chamber to remove volatile compounds generated during the reaction. A grid or a perforated plate separates the plasma source and the coated membrane.

A method for producing a metal foam includes depositing metal-containing particles and blowing-agent-containing particles by cold spraying. A layer formed in this manner is formed from metallic particles and particles containing blowing agent, wherein the blowing agent forms the core of coated particles. The shell of said particles is likewise metallic, such that it is easier to deposit said particles together with the metallic particles. Therefore, a higher concentration of blowing agent can advantageously be produced in the layer. Greater possibilities are advantageously produced thereby to provide the porous layers with required pore profiles.
