Abstract
The corrosion behaviour of Zn-Co compositionally modulated multilayers (CMM ) was studied using corrosion potential measurement and the neutral salt sp ray (NSS) method. It was established that the corrosion potentials of the C MM, deposited from a single bath, are significantly more positive than thos e deposited from a dual bath. The best corrosion resistance was found for m ultilayers consisting of four sublayers, each 3.0 mu m thick, deposited bot h from a dual bath and from a single bath (with an oversublayer of Zn-Co 1% ).
