Abstract
The kinetics and mechanism of the electroreduction of anodic layers fo rmed on copper in sodium phosphate solution at pH values close to neut rality have been investigated using potentiodynamic and potentiostatic techniques. The participation of copper oxide and copper phosphate co mponents in the anodic layer is concluded, and their electroreduction can be modelled through nucleation and growth formalisms by considerin g a charge transfer control for the process.
