Anomalous electrodeposition of Co-W coatings from a citrate electrolyte due to the formation of multinuclear heterometallic complexes in the solution

It is shown that the anomalous electrodeposition of Co-W coatings in a citrate electrolyte occurs as a result of the formation in the bulk of the solution of multinuclear heterometallic complexes with their structure (composition) defined by the solution and near-electrode layer pH values.
