Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung von Oxyd- und Silikatschichten auf Metalloberflächen in einem flüssigen Elektrolyten, insbesondere für die Metalle Aluminium, Magnesium und deren Legierungen, sowie für Tantal, Titan, Niob und Zirkonium. Es wird vorgeschlagen, dass bei der Herstellung der Oxyd- und Silikatschichten im flüssigen Elektrolyten eine bipolare Stromquelle verwendet wird, deren Polarität verändert werden kann.

The invention relates to a process for the preparation of oxide and silicate layers on metal surfaces in a liquid electrolyte, in particular for the metals aluminum, magnesium and their alloys, and for tantalum, titanium, niobium and zirconium. It is proposed that in the preparation of the oxide and silicate layers in the liquid electrolyte, a bipolar current source is used whose polarity can be changed.
