Abstract
High temperature superconductive ceramic coatings of the Y(Ba, K)2Cu3O 7 compound were plasma-sprayed on a silver substrate and these coated plates were subsequently surface treated by an excimer laser. The effe ct of the excimer laser irradiation and the subsequent heat treatment on the main features of the coated surface was evaluated in terms of s urface modifications, microstructural and crystallographic/stoichiomet ric changes and electrical/magnetic properties of the superconductive compounds. Superconductivity was enhanced after the post-processing he at treatment.
