Abstract :
[en] We have studied the sintering parameters of YBa2Cu3O7-x (YBCO) coatings produced by
electrophoretic deposition (EPD) on Ag and Ni substrates. The maximal sintering temperature is
~ 930°C due to partial melting and chemical contamination for Ag and Ni substrates
respectively. Increasing the sintering duration does not improve significantly the densification.
When Ar sintering atmosphere is used, the coating density is strongly increased on Ag substrates
while adhesion is poor on Ni substrates. The Ar-sintered YBCO coating deposited on planar Ag
substrate displays a significant magnetic shielding effect for low frequency applied magnetic
induction.
