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. Niobium is electrochemically and chemically coated, by irradiating the workpieces with aluminum oxide, with treated with an alkaline cyanide bath, galvanically with pre-nickel-plated with an acidic nickel chloride bath, again with treated in an alkaline cyanide bath and then in known electrochemically or chemically be coated with the desired metal. The own Properties of the coatings are particularly sufficient Requirements for superconducting workpieces.
