Selective anodic dissolution of phases in copper-based alloys in citric acid solution

Abstract

The anodic behaviour of as-cast and homogenized binary copper-based alloys with Zr, Cr, Al, Si and Sn in 50% citric acid solution has been studied by the potentiostatic method. At positive potentials all as-cast and homogenized alloys with low additions of alloying elements behave in a manner similar to that of copper. However, there is an essential difference between the polarization curves for copper with 8% Al and those for copper. The differentiation ratio of dissolution rates and optimum values of dissolution potentials were calculated using the data for as-cast alloys. The highest differentiation ratio was found for the Cu-8% Al alloy. On the basis of calculated potentials, a number of experiments were performed in order to separate the phases.
