Methods for providing laminated coatings on metal articles using electroplating methods such as barrel plating, vibratory plating, rocker plating or other non-rack methods that involve movement of articles to be plated in a containment apparatus, as well as articles made from such processes. Embodiments of such processes involve mass-transfer modulation to provide compositionally modulated coatings.
