摘要

The method for the production of a multi-layered coil (100), comprises spraying carrier particles areawisely on the surface of a magnetic substrate (5) or magnetic form part by cold gas spraying for forming a carrier layer (15), where the carrier particle has weak electrically conducting or electrically insulating characteristics, and spraying conductive particles areawisely on the carrier layer by cold gas spraying for forming a conductive layer, where the conductive particles have electrically superconducting characteristics. The method for the production of a multi-layered coil (100), comprises spraying carrier particles areawisely on the surface of a magnetic substrate (5) or magnetic form part by cold gas spraying for forming a carrier layer (15), where the carrier particle has weak electrically conducting or electrically insulating characteristics, spraying conductive particles areawisely on the carrier layer by cold gas spraying for forming a conductive layer, where the conductive particles have electrically superconducting characteristics, forming the conductive layer by mechanical processing using laser in a helical web, imbedding the conductor web through spraying further carrier particles under formation of a further carrier layer, spraying the conductive particles under formation of a further conductive layer on the further carrier layer, forming the further conductive layer by mechanical processing using laser in further conductive web, and providing an electrically superconductive connection (20) for further conductive layers. The electrically conductive connection is carried out according to a tapping-hole spraying process. The recess is mechanically provided in the carrier layer limiting on the electrically conductive conductor layer to be connected so that the recess is bored by the carrier layer. The recess is filled with electrically superconductive material. The weak electrical conductive or electrically insulated characteristics are provided through copper, and/or through niobium-titanium or niobium-tantalum. The conductive particles are contained for the part of the chemical component of high temperature super conductors, and/or the substrate or the mold part has a micro-structure or micro-texture that corresponds to the micro-structure or micro texture of a high temperature super conductors. Nanoparticles are used as carrier particle and/or as conductor particles. A reactive gas such as oxygen is added during cold gas spraying of the gas beam. After the application of the carrier particles and/or the conductor particles, a heat treatment of the coated substrate or mold part is carried out. Independent claims are included for: (1) a device for the production of a multi-layered coil; and (2) a multi-layered coil.
