We studied the electrochemical properties of a sacrificial-anode alloy based on aluminum and magnesium, into which calcium, along with zinc, was introduced as an antipassivator. For the production of this alloy, we used waste and scrap of aluminum-magnesium alloys. In addition to iron and silicon admixtures, it contains a significant amount of copper. Aluminum-based solid solution is the main phase of the new sacrificial-anode alloy, and its second phase represents Cax Zny Alz intermetallic compound, which is distributed uniformly over the volume. The proposed alloy was used for the corrosion protection of seagoing ships of the Baltic Steamship Line. It was also tested successfully in waters of the Pacific and in corrosive brackish soils of Southern Ukraine and Middle Asia. These sacrificial anodes have an efficiency of ∼85% and a stationary potential in seawater of −1.10 v relative to a copper-sulfate reference electrode. [ABSTRACT FROM AUTHOR]
