Abstract

Niob wird elektrochemisch und chemisch beschichtet, indem die Werkstücke mit Aluminiumoxid bestrahlt, mit einem alkalischen Cyanidbad behandelt, galvanisch mit einem sauren Nickelchloridbad vorvernickelt, nochmals mit einem alkalischen Cyanidbad behandelt und danach in an sich bekannter Weise elektrochemisch oder chemisch mit dem gewünschten Metall beschichtet werden. Die Eigen­ schaften der Beschichtungen genügen insbesondere den Anforderungen an supraleitende Werkstücke.
