Abstract
There is disclosed a processing solution for metal replacement for metal aluminum or an aluminum alloy. The processing solution is used for surface processing of an underlying aluminum material. The processing solution for metal replacement removes an oxide film on the underlying aluminum material and suppresses corrosive attack to it to allow a plating film having high smoothness and good plating appearance to be deposited on the underlying aluminum material. The processing solution for metal replacement at least includes a metal salt capable of being replaced with aluminum, and an alkaline compound. A quaternary ammonium hydroxide is contained in the processing solution for metal replacement as the alkaline compound.
