By burying the sacrificial anodes near the metal elements and exposing them to oxidizing agents, the sacrificial anodes oxidize faster than the existing metal before the metals react with electrolytes, consuming all the oxidation factors. <br \/>Consequently, the sacrificial anodes are sacrificed in place of the metals and ultimately corroded. Using these types of anodes can increase the useful life of steel components.<\/p>\n<p>MSA\u2122 includes a backfill and a cable in addition to the magnesium anode. The backfill acts as a protective layer for the anode. Backfills are formed by different mixtures of compounds, such as gypsum, bentonite, and sodium sulfate to withstand environmental conditions. The role of backfills is to provide stability to the anode potential, prevent anode polarization, reduce the resistance between the anode and soil, increase the anode&#8217;s output current, create uniform corrosion on the anode, reduce self-corrosion of the anode, and enhance the efficiency of the anodes. Cables are responsible for the transport of anodes and cathodes. Magnesium sacrificial anodes are categorized into standard and high-potential types based on chemical composition. Standard magnesium sacrificial anodes have an open-circuit potential of -1.5, and they can achieve up to 60% efficiency.<\/p>\n<p>On the other hand, high-potential magnesium sacrificial anodes have an open-circuit potential of -1.7 and can reach up to 50% efficiency. Therefore, the applicant should choose the appropriate sacrificial anode based on the existing conditions and desired objectives.<\/p>\n<p>[\/col]<br \/>\n[col span=&#8221;6&#8243; span__sm=&#8221;12&#8243;

Additionally, ensuring the substrate is adequately moistened before anode installation contributes to their effectiveness. Once the anodes are positioned, the cables connecting them should be properly linked to the respective metal.
