Abstract: Copper is electroplated directly onto aluminum by immersing an aluminum workpiece in an aqueous alkaline plating bath containing a divalent copper salt and an amine capable of complexing the copper, and passing an electric current through the plating bath using the workpiece as the cathode. The deposits which are obtained are strongly adherent and the method avoids the need for complicated mechanical or chemical pretreatment of the workpiece.

Abstract translation: 通过将铝工件浸入含有二价铜盐和能够络合铜的胺的水性碱性电镀液中，并且使用工件作为阴极使电流通过电镀槽，将铜直接电镀在铝上。 获得的沉积物具有很强的粘附性，并且该方法避免了对工件进行复杂的机械或化学预处理的需要。
