Abstract

Bei einem Verfahren zur Herstellung von Schutzschichten einheitlicher Farbtönung durch Beizen auf gewalzten Flacherzeugnissen aus Titanzink werden die Flacherzeugnisse in einem Beizbad mit Schwefelsäure und Salpetersäure enthaltender Mischsäure gebeizt. Um eine Zerstörung der Schutzschicht zu vermeiden, werden diese durch Auftragen von chromathaltigem Polymeren unter Bildung einer Schutzschicht passiviert.
