Abstract

Es wird ein Glänzverfahren für Teile aus Aluminium oder Aluminium-­ Legierung beschrieben, das sich insbesondere dadurch auszeichnet, daß die Teile in einem mittels Gleichstrom betriebenen alkalischen Elektrolyten der Zusammensetzung:
Na₃PO₄ (Trinatriumphosphat) 120 g/l
NA₂CO₃ (Dinatriumcarbonat) 330 g/l
AlPO₄ (Aluminiumphosphat) 10 g/l
Extrakte aus Buchenholz 5 ml/l
bei einer Betriebstemperatur von etwa 70 - 80 o C behandelt werden. A glossing process for parts made of aluminum or aluminum alloy is described, which is characterized in particular by the fact that the parts in an alkaline electrolyte operated by direct current having the composition:
Na₃PO₄ (trisodium phosphate) 120 g / l
NA₂CO₃ (disodium carbonate) 330 g / l
AlPO₄ (aluminum phosphate) 10 g / l
Extracts from beech wood 5 ml / l
be treated at an operating temperature of around 70 - 80 o C.
