Abstract

A high temperature super-conduction clad-film conductor and its preparation method relates to the method combining an IBAD technology with chemical solution method filming technology. The clad-film conductor is composed of a super-conduction protection layer, YBCO super-conduction layer, a CeO2 buffer layer, an IBAD YSZ buffer layer and a metal substrate. The method includes preparing a double-shaft buffer layer and an additional buffer layer on the metal basic belt material, then, preparing YBCO super-conduction layer and a lost super protection layer on these buffer layer material substrates to get the high temperature super-conduction clad-film conductor.
