PROCESSO PARA A ASPERSAO TERMICA DE MATERIAIS SUPERCONDUTORES DE CERAMICAS DE OXIDOS

摘要

The invention relates to a method for thermally spraying oxide-ceramic materials having an overall composition corresponding to that of an oxide-ceramic superconductor. The powdered material is fed into the heating flame of the burner in which it is incipiently or completely melted and it strikes a substrate material as a spray jet. Oxygen, dinitrogen oxide or ozone is additionally fed into the heating flame and/or the spray jet in order to re-enrich the material, which loses oxygen during thermal spraying, with oxygen. This procedure makes a thermal post-treatment in an oxygen atmosphere, which would otherwise be necessary, superfluous.
