Sažetak
Several studies have focused on alloying and structural modifications of aluminium alloy sacrificial anodes using different activators. The present work explores the effect of the addition of small quantities of the alloying element, which will not affect the basic advantages of aluminium, on electrochemical properties and homogeneity of the alloy with the commercial name Akalpro. The electrochemical characterization of aluminium anodes was carried out by observation of closed circuit potentials of sacrificial anodes sealed on steel plates and immersed in seawater. Protector achieved a stable closed circuit potential -1.173 V vs. Cu/CuSO4 electrode, energetic capacity 2512 A h / kg and high efficiency degree of anodic material (~ 84%). Properties of Akalpro such as the low specific weight, negative electrode potential and high current capacity and the fact that it does not sparkle when hit and does not release significant quantities of hydrogen made possible its practical applications as sacrificial anodes in ballast tanks, for transportation of oil and inflammable liquids
