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.In a process for the production of protective layers more uniform Color tint by pickling on rolled flat products Titanium zinc becomes flat products in one Pickling bath containing sulfuric acid and nitric acid Mixed acid pickled. To destroy the protective layer too avoid them by applying chromate Passivated polymers to form a protective layer.
