Abstract: Suitable processing methods for high-temperature superconductors are essential to the application of these new materials. Plasma spraying is profitable for this purpose, especially in the case of large area coatings. In this work, the deposition of thick YBa$_{2}$Cu$_{3}$O$_{7-x}$ and Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8}$ layers onto metallic substrates by vacuum plasma spraying is described. Various commercially available superconducting powders are tested concerning their possible use for plasma spraying. The suitability of nickel based alloys and stainless steel as substrate materials is investigated.After plasma spraying the coatings are not superconducting. For reconstruction of the superconducting phases on the one hand, and improvement of the superconducting properties of the coatings on the other, annealing and melt texturing experiments are done. Their effects on the coating substrate compounds are analysed.
