A low-pressure plasma spraying technique for depositing high T/sub c/ Y-Ba-Cu-O thick films has been developed. Films with a thickness range of 20--100 ..mu..m have been prepared by using Y/sub 0.3/Ba/sub 0.7/CuO/sub x/ powders. After post-annealing in oxygen for 1 h at 950 /sup 0/C, the films, which were deposited on a nimonic alloy substrate heated at 650 /sup 0/C during spraying, exhibited a zero resistance temperature of 90.6 K with a transition width (90%--10%) of 2 K and a critical current density (77 K, 0 T) of 690 A/cm/sup 2/.
