Corrosion control in cooling water systems is primarily effected with inorganic inhibitor formulations. The most commonly used treatments are phosphate and chromate-based. These materials are “passivating inhibitors”. The mechanism of corrosion inhibition by phosphates,1-3  chromate4-5  and the combination6-7  has been known for many years. One purpose of this presentation is to indicate the use and limitations of a potentiodynamic polarization technique in the investigation of corrosion inhibitors in cooling waters.
