초록

$YBa_2Cu_3O_{7-\delta}$ superconductor films have been prepared on silver substrates by electrophoretic deposition. As silver does not react with $YBa_2Cu_3O_{7-\delta}$ compound and has little influence on its superconductivity, it is usually doped in $YBa_2Cu_3O_7$ to improve the strength of the material and eliminate micro-cracks. It has been proved that Ag additive can lower the melting temperature of $YBa_2Cu_3O_{7-\delta}$ and act as linking bridge among $YBa_2Cu_3O_{7-\delta}$ particles, thus in this paper Ag doped $YBa_2Cu_3O_{7-\delta}$ thick films are prepared by electrophoretic co-deposition. As there are only some referenced experience formula and models for co-electrophoretic deposition and does not exist unified explanation, the behavior of Ag particles during co-electrophoretic deposition is also studied.
