Abstract

This work presents the characteristics of Bi-2212 coatings on silver substrates obtained by thermo-spraying. The system allows moving the substrate to obtain coatings over surfaces several centimeters long. The thickness of the superconducting layer can be controlled modifying the thermo-spraying parameters and the substrate speed. The phase distribution and evolution during annealing has been monitored. An important amount of Bi-2212 phase is on the sample after the thermo-spraying process and this phase can be aligned by subsequent laser zone melting. The influence of the different treatments applied on the phase composition, microstructure and superconducting properties is shown.
