    Abstract: Die Erfindung betrifft ein Verfahren zur Gewinnung goldfarbener Aluminiumoxid-Schichten, in dem das Färben der oxidierten Oberfläche des Aluminiums oder der Aluminium-Legierungen durch ein elektrolytisches Verfahren in einem eine Alkansulfonsäure und ein Alkansulfonat des Silbers enthaltenden Elektrolyten erfolgt, sowie die Verwendung der nach diesem Verfahren hergestellten goldfarben eingefärbten Werkstücke auf Basis von Aluminium oder Aluminium-Legierungen zu dekorativen Zwecken. Des weiteren betrifft die Erfindung eine Elektrolytlösung zur goldfarbenen Einfärbung der oxidierten Oberfläche von Aluminium oder Aluminium-Legierungen durch ein elektrolytisches Verfahren und die Verwendung von einem ein Alkansulfonat des Silbers enthaltenden Elektrolyten zur goldfarbenen Einfärbung von Aluminiumoxid-Schichten auf der Basis von Aluminium oder Aluminium-Legierungen in einem elektrolytischen Verfahren.

    Abstract translation: 本发明涉及一种用于生产金色氧化铝层，从而使铝或铝合金的氧化表面被着色到电解质含烷烃磺酸和通过电解法的手段银烷烃磺酸盐的方法。 因此，本发明涉及使用由所述方法用于装饰目的产生的金色铝或铝合金工件。 本发明还涉及到在通过电解法的手段金着色的铝或铝合金的氧化表面的电解质溶液，以及使用的电解质的含有氧化铝层的在铝金着色银链烷磺酸盐 和铝合金在电解方法。
