Impressed Current Silicon Iron Anode

High Silicon Cast Iron Anode has longer life than sacrificial anodes in cathodic protection due to their less consumption rate, durability and strength. High Silicon Cast Iron Sacrificial Anode is working well for electrical conductivity. Impressed current anode that will form a thin passive barrier film of silicon dioxide on the metal surface, after oxidation takes place. The film has high resistivity and chemistry stability, which is in passive state under acid conditions, so it can reduce the dissolving rate for anode. Moreover, after covered by Chromium, the protection film of SiO2 of HSCI is develped to resist corrosion from alkali and chloride ion, so that anode can be applied for strong choloride conditions. Therefore, HSCI Anode with Chromium adapts to all kinds of land and water environment
