Abstrakt: The anodic behaviour of composition modulated Zn–Co multilayers (CMM) electrodeposited from single and dual baths was studied. Multilayers with thickness of the individual sublayers 0.3 and 3.0μm were electrodeposited galvanostatically. It was established that most of the CMM coatings obtained from dual baths dissolve at potentials that are close to those for pure Co coatings. CMM coatings obtained from a single bath dissolve at potentials between the dissolution potentials of pure Co and pure Zn coatings. With increase in the number of sublayers in CMM coatings with equal total thickness, deposited both from dual or single baths, regardless of their individual sublayer thickness and sequence, potentials of the stripping peaks are shifted positively.
