Corrosion on the submerged metal surfaces of a treatment mechanism immersed in an electrolyte and placed within a concrete reinforced basin will be under the control of the galvanic couple. This exists between the mechanism (anode) and the re-bars (cathode). The anode-cathode relationship will determine the corrosion rate of the steel structure exposed to the electrolyte. On poorly coated structures, corrosion activity may be spread over the entire mechanism. On a well coated structure, all corrosion activity will occur at the flaws in the coating system where metal penetration can develop in a relatively short period of time. See Fig. 1, 1A, 1B.
