Zusammenfassung:Plasma sprayed Y sub 1 Ba sub 2 Cu sub 3 O sub 7--x coatings obtained on stainless steel substrates showed superconductivity after being annealed in oxygen at 950 deg C for about 1 h. Coatings thinner than 100 mu m do not show superconductivity. The current density varied from 3 to 15 A/cm exp 2 depending on the specimen. Coatings compared with coarse powder specimens. 6 ref.--AA
