摘要：

Yttria-stabilized-zirconia (YSZ) buffer layers on polycrystalline alumina substrate were fabricated by spraying a suspension consisting of ultrafine YSZ ponders. It was found that the spraying conditions such as the flow rate of carrier gas and the aperture of spray nozzle had a great influence on the mechanical properties of the sprayed buffer layers and also on the J(c) values of YBCO thick films processed on these buffer layers. The maximum J(c) value of screen-printed YBCO film, fired by the solid-phase sintering method, was about 470 A cm(-2) at 77 K, O T. This value was about four-fifths of those for films on single-crystal YSZ substrates. (C) 1998 Elsevier Science S.A.
