Abstract

The structure and electrical resistivity of YBa₂Cu₃O_{7 – δ}-based nanostructured ceramics before and after exposure to the high-enthalpy argon plasma flow are investigated. It is demonstrated that the plasma-flow processing can strengthen the intergrain bonds in the surface layer of the ceramics and change its oxygen stoichiometry index.
