The application of cast protectors in systems of cathodic protection of metal structures and structures from electrochemical corrosion is well known. Alloys based on aluminum, magnesium and zinc are widely used as sacrificial materials for the manufacture of sacrificials. The choice of designs and standard sizes of protectors is carried out taking into account the provision of the required service life of the protector protection systems in various operating conditions. The structure of cast protectors plays an important role in stabilizing the electrochemical characteristics of sacrificial materials. The paper describes the characteristics of sacrificial alloys and cast sacrificials, and also shows the influence of casting conditions on increasing the values of the efficiency factor (KPI) of sacrificial materials.
