Abstract
A process for the preparation of aluminum and aluminum alloys with a view to the application of a copper coating in a bath based on pyrophosphate, whose process is characterized by the following features, of which the former can mainly be used either in isolation already according to certain combinations with others: a) consists essentially of treating the surface of aluminum or aluminum alloy with a bath comprising a dilute aqueous solution of a zinc salt, the concentration of this solution being in total salts of at most about 130 g per liter, an alkaline compound and a chelating reagent that has a stability constant for zinc log k1 of about 4.5 to 19 and a water-soluble chelating agent and has a stability constant for zinc log k1 about 1.5 to 4, and a small proportion of a copper salt.
