In a method for galvanizing, in particular electrolytically coloring an anodized aluminum surface in a bath (1) containing heavy metal ions, in particular tin (II), Ni, Co or Cu (II) ions, the heavy metal is deposited in the anodized surface by means of an alternating current. The degree of galvanization, in particular the degree of coloring, is determined by determining the integral (A.s) of at least the negative phase of the current through the circuit (16) in which the bath is included over the time for the operation. In particular, the determination of the said integral value is only carried out for the negative phase of the current. |
