Abstract

Aluminierte Teile werden in einem wäßrigen Bad ano­ disiert, das pro Liter 1050 bis 1400 g Schwefelsäure der Dichte 1,84 enthält und gegebenenfalls 1 bis 100g eines mehrwertigen Alkohols und 1 bis 100 g einer mehrbasi­ schen organischen Säure. Anodisiert wird bei einem PH-­ Wert unter 1 mit einer Stromdichte von 0,5 bis 3 A/dm² bei 0 bis 30°C. Das Verfahren kann bei partiell aluminierten Teilen ohne Zerstörung des Grundwerkstoffes eingesetzt werden. Aluminized parts are ano in an aqueous bath dosed that 1050 to 1400 g of sulfuric acid per liter Contains density 1.84 and optionally 1 to 100 g of one polyhydric alcohol and 1 to 100 g of a polybasic organic acid. Anodizing is done with a PH Value below 1 with a current density of 0.5 to 3 A / dm² at 0 to 30 ° C. The process can be used for partially aluminized Parts used without destroying the base material will.
